Grid Management Renewable Energy Balancing Power Generation

Balvinder Singh

System operators face a proliferation of power electronics interfaced devices such as HVDC transmission lines, wind and solar generation in their grids. Depending on the jurisdiction, the instantaneous share of electrical energy produced from renewable energy sources occasionally reaches 150%. However, to operate a power system with sustained high levels of renewable energy, several operational challenges need to be addressed. The goal of this survey paper, which is one of the products of CIGRE joint working group C2/B4.38, is to identify such challenges. To this extend, extensive literature review and survey among and discussions with system operators throughout the world were performed. This paper identified several operational challenges that were validated by system operators. These challenges are grouped in the following three categories: (i) new behavior of the power system, (ii) new operation of the power system and (iii) lack of voltage and frequency support. For each of the identified challenge, a description, practical examples and relevant references are provided.

As global power systems transition to a new energy future, transmission networks are increasingly required to enable renewable generation to integrate into energy markets. The changing generation mix is driving changes to power flow patterns which increase transmission constraints and curtailment of zero fuel cost and emissions-free generation. Developing transmission infrastructure to relieve network constraints involves capital intensive investment and significant costs to end users. By improving line utilisation, utilities can reduce generation curtailment, provide increased sharing of geographically diverse renewable energy resources while saving considerable capital investment by deferring or eliminating augmentation costs. Modular Flexible Alternating Current Transmission System (M-FACTS) devices are one such technology that can be employed to optimise line power flows, allowing utilities to enhance the capability of existing networks, whilst minimising overall network investment cost and risk. Recent developments leverage Static Synchronous Series Compensator (SSSC) technology to provide a modular solution to improving network utilisation. The modular SSSC (M-SSSC) is a member of the M-FACTS product family whose modular nature enables a flexible, no-regrets approach to network investment. These solutions are economic and allow incremental network augmentation, removing the stumbling block of high cost-of-entry for many projects, in much quicker timeframes than traditional network investments. Standard components come off-the-shelf, enabling shorter project lead-times, matching the timeline of renewable generation developments, for example.

The wi-fi energy transfer (WPT) is an emerging era with increasingly more ability packages to transfer energy from a transmitter to a cellular receiver over a noticeably huge air gap. but, its extensive utility is hampered due to the relatively low performance of modern wireless power switch (WPT) structures. This study gives an idea to maximize the performance in addition to to increase the quantity of extractable electricity of a WPT system operating in resonant operation. The proposed method is primarily based on actively modifying the equal secondary-side load impedance by controlling the section-shift of the active rectifier and its output voltage degree. The offered hardware prototype represents an entire wireless charging machine, consisting of a dcÃ¢â‚¬â€œdc converter that is used to price a battery at the output of the system. Experimental results are shown for the proposed concept in comparison to a traditional synchronous rectification approach. The supplied optimization technique sincerely outperforms trendy solutions in phrases of efficiency and extractable power.

Journal For Research

A number of factors are contributing to increases in renewable energy production in the United States (and beyond). These factors include rapidly declining costs of electricity produced from renewable energy sources, regulatory and policy obligations and incentives, and moves to reduce pollution from fossil fuel-based power generation, including greenhouse gas emissions. While not all renewable energy sources are variable, two such technologies – wind and solar PV – currently dominate the growth of renewable electricity production. The production from wind and solar PV tries to capture the freely available but varying amount of wind and solar irradiance. As the share of electricity produced from variable renewable resources grows, so does the need to integrate these resources in a cost-effective manner, i.e., to ensure that total electricity production from all sources including variable renewable generation equals electricity demand in real time. Also, a future electric system characterized by a rising share of renewable energy will likely require concurrent changes to the existing transmission and distribution (T&D) infrastructure. While this report does not delve into that topic, utilities, grid operators and regulators must carefully plan for needed future investments in T&D, given the lead times and complexities involved.

Large Scale Grid Integration of Renewable Energy Sources - Way Forward

Spark Network

With a growing demand for more energy from subscribers, a traditional electric grid is unable to meet new challenges, in the remote areas remains the extension of the conventional electric network very hard to do make prohibitively expensive. Therefore, a new advanced generation of traditional electrical is inevitable and indispensable to move toward an effective, economical, green, clean and self-correcting power system. The most well-known term used to define this next generation power system is micro grid (MG) based on renewable energy sources (RES). Since, the energy produced by RES are not constant at all times, a wide range of energy control techniques must be involved to provide a reliable power to consumers. To solve this problem in this paper we present a fuzzy logic control of isolated hybrid systems (HRES) including renewable energy in micro-grids to maintain a stability in voltage and frequency output especially in the standalone application. The considered HRES combine a wind turbine (WT) and photovoltaic (PV) panels as primary energy sources and an energy storage system (ESS) based on battery as a backup solution. Simulation results obtained from MATLAB/Simulink environment demonstrate the effectiveness of the proposed algorithm in decreasing the electricity bill of customer.

The Advanced Distribution Management System – ADMS – brings together distribution management system (DMS), supervisory control and data acquisition (SCADA) and outage management system (OMS) technologies , along with control room applications, on one, secure platform with a single user interface. With this comprehensive mission critical solution, the electric utility can monitor, analyze and control the distribution network to improve the level and quality of service. At its core is the network model representing the as-operated state and based on the as-built state defined by the geographic information system (GIS). A load flow algorithm responds quickly to data sourced from throughout the network to analyze the balanced, unbalanced and dynamically changing network in real time. Users across the network – operators, dispatchers, management, planning engineers and others – have consistent visualization of model results in geographic, schematic and single-line diagram views. State estimation validates viewed data and estimates non-telemetered points to achieve a complete network representation. With this accurate network model and a portfolio of robust functionalities, the utility is empowered with continuous, real-time analysis of the operational state of the network that enables self-healing capabilities. Demand can be managed through reduction of technical losses; by forecasting near-term load and applying volt/VAR control for peak shaving; and by securely integrating and managing distributed energy resources, including energy storage, to flatten the daily load curve. These and other options enabled by ADMS are key to managing demand in the face of increasing energy usage, surging energy costs and network infrastructure instability due to aging. The ADMS represents the evolution of control room technology that will help utilities mobilize to meet increasing consumer demand and environmental obligations and reap many of the benefits all stakeholders expect from their smart grid investments.

ROLE OF POWER ELECTRONICS IN NON-RENEWABLE AND RENEWABLE ENERGY SYSTEMS

International Journal of Technical Research & Application

Emergency back-up power supply units are necessary in case of grid power shortage, considerably poor regulation and costly establishment of a power system facility. In this regard, power electronic converters based systems emerge as consistent, properly controlled and inexpensive electrical energy providers. This paper presents an implemented design of a grid-tied emergency back-up power supply for medium and low power applications. There are a rectifier-link boost derived DC-DC battery charging circuit and a 4-switch push-pull power inverter (DC-AC) circuit, which are controlled by pulse width modulation (PWM) signals. A changeover relay based transfer switch controls the power flow towards the utility loads. During off-grid situations, loads are fed power by the proposed system and during on-grid situations, battery is charged by an AC-link rectifier-fed boost converter. Charging phenomenon of the battery is controlled by a relay switched protection circuit. Laboratory experiments are carried out extensively for different loads. Power quality assessments along with back-up durations are recorded and analyzed. In addition, a cost allocation affirms the economic feasibility of the proposed framework in case of reasonable consumer applications. The test-bed results corroborate the reliability of the research work.

Submodule overcurrent caused by DC pole-to-pole fault in modular multilevel converter HVDC MMC-HVDC system is one of the important research objects about its electrical characteristics. In this paper, the fault mechanism before and after the converter blocked was analyzed respectively and the circuit model for the analysis of submodule overcurrent was explored. The analytic equation for overcurrent calculation was deduced and a detailed analysis was also performed. The changes of submodule overcurrent stress with different circuit parameters were obtained and the key issues were also summed up. The results indicate that the submodule overcurrent is the AC system three-phase short-circuit current superposed the discharging current before the converter blocked, and the submodule overcurrent is the AC system three-phase short-circuit current superposed the valve reactor freewheeling current after the converter blocked. From the computation and simulation results, it is concluded that the analytical method is feasible and its calculation results are comparatively precise.

Due to the depletion of fossil fuels, coal, and oil, traditional electricity generation has a difficult task for utilities. A cheaper and more efficient method of doing this is required. A different source is required to fulfill the consumers power requirements. The alternate source should be sustainable and capable of meeting the consumers requirements. The integration of renewable energy into the grid is a useful way to fulfill demand. Renewable energy integration confronts three major problems frequency variation, power quality concerns, and power system instability. The following problems were of critical importance. An analytic hierarchy approach based expert system is utilized to identify and categorize power quality incidents. Before, it could sense things like sag, swell, transients, harmonics, interrupts, and flickers. An error free event classification system has been suggested. Simplified procedure allows for improved detection and categorization of power quality incidents. an investigation of power quality incidents and their mitigation using unified power quality conditioners UPQC An Adaptive Neuro Fuzzy Inference System ANFIS is used to minimize various power quality issues. Integrating renewable energy sources efficiently minimizes the environmental impact. The suggested method provides a solution to voltage unbalances and lowers overall harmonic distortion at the point of common coupling PCC . The addition of an ANFIS controlled DVR is used to reduce voltage irregularities caused by integrating renewable energy sources and faults in the transmission line. An artificial fault was added to power quality events with the goal of making use of renewable energy. To minimize the adverse effects of power quality incidents, the ANFIS controlled DVR proposal is in place. ANFIS controlled DVR is contrasted to a traditional technique of surveillance. Distributed static compensator D STATCOM is used to prevent voltage flickers, and total harmonic distortion, caused by nonlinear loads. D STATCOM is suggested to use three control methods Instantaneous power theory, Synchronous vector PI Control, and Harmonic elimination. Under extreme load circumstances, the D efficacy STATCOMs is evaluated. The suggested expert system and the bespoke power devices will be analyzed and discussed using various control techniques.

With the rapid demand of electricity, the installation of power electronics based equipment in power distribution system has grown rapidly for ac dc system coupling, system protection, alternative energy source interface, etc. This paper focus on power electronic component and system modelling techniques and three phase ac dc power flow analysis for power distribution systems. The research discusses the models that are developed for unbalanced power electronic converters, such as thyristor converters, diode rectifiers, and Pulse Width Modulated PWM converters. The modelling approach captures the imbalance of distribution systems using three, delta connected, single phase converters. To perform system analysis, these models have been incorporated into two types of ac dc power flow solvers A three phase backwards forward sequential solver and a three phase unified solver using the modified nodal analysis method. Both solvers have been applied to unbalanced radial and weakly meshed distribution systems. Finally, an ac dc system hardware test bed was created to validate the proposed models and the performance of the power flow solvers. Extensive hardware tests, time domain simulations, and steady state analysis have been performed.

The global environment is degrading and all efforts are being made to reverse the situation. Power generation based on fossil fuel is partly responsible for the polluting emissions. Because of this, renewable (non-pollutant) energy sources have received a lot of attention in the power community. The cost of renewable energies is expected to fall as the demand increases. Power conversion interfaces (PEI) are needed to integrate renewable energy sources with the existing electrical power system. This paper provides a brief introduction on power conversion interfaces.

HVDC technology is developing fast and HVDC grids are increasingly seen as a possible and feasible solution to manage the future power system with large amounts of renewables in a secure and cost-effective manner. However, systems with significant amounts of DC transmission behave in a fundamentally different manner when compared to the traditional AC power system. The integration of HVDC systems introduces new fast dynamics on different time frames and adds controllability to the combined system. As a result, the modeling and control of the entire interconnected system needs to be reevaluated in order to accurately compute the system behavior, both from the AC and DC system. This survey paper gives an overview of the current research in the field of HVDC grids focusing on the interaction of the AC and DC system. The converters and their behavior are discussed in greater detail. A second component which is discussed is the DC breaker. Both devices operate fundamentally different than their AC counterparts. The fast interaction between AC and DC systems requires changes in the manner in which the modeling and computation of the system is done, both at the DC and the AC side. Although these considerations are needed within all relevant time frames, two relevant cases are specifically addressed in this paper: the connection of offshore wind power through a HVDC system and the optimal operation of the power system with a strong presence of HVDC.

Flexible ac transmission systems (FACTSs) and voltage-source converters, with smart dynamic controllers, are emerging as a stabilization and power filtering equipment to improve the power quality. Also, distributed FACTSs play an important role in improving the power factor, energy utilization, enhancing the power quality, and ensuring efficient energy utilization and energy management in grids. This paper presents a literature survey of FACTS technology tools and applications for power quality and efficient utilization of electric system. There are some drawbacks of FACTS devices. These drawbacks can be fulfilled by using new compound, scalable, light weighted and cost effective devices that are distributed-FACTS (D-FACTS). D-FACTS controllers are distributed version of conventional lumped FACTS controllers and their cost is low due to lower ratings of component and reliability also increases due to redundancy of devices. The Enhanced Power Flow Controller (EPFC) is a D-FACTS controller which is distributed version of thyristor controlled series controller. DPFC controllers are used in series at small distance gap at every 5-10 km distance with transmission line to control the power flow. This paper discusses extensive review of the DPFC controller and its application in modern power system era.

Distributed energy units cannot be directly integrated into the power grid due to their inherently varying output. An interfacing technology is required. The power electronic interface is used for connecting distributed energy resources to the smart grid. It can also be used in any type of electric vehicles. It does not store energy in its circuitry. It receives power from the distributed energy source and converts it to power at the required voltage and frequency. This paper provides a brief introduction on power electronic interface. Matthew N.

The utilization of energy has increased manifold because of the industrial revolution. The development of the induction motor by Nikola Tesla in 1888 triggered the increasing demand of electrical energy in the industrial world and also its usage for artificial lighting. Higher amount of energy required for present society is provided by means of electrical energy. Highly complicated power systems have been constructed to deal with the increasing demand. The development in electric power production is focused on the interconnecting the transmission lines, generators and loads into huge integrated systems, which helps in providing reliable and quality power system to the consumers.Power system stability is an idea that focuses on the way the system adjusts with the occurrence of disorder. These disorders can result because of switching off a load or a modification in the mechanical input to the system. Because of these disturbances oscillations may happen in the system that could ultimately build up to a larger extent, resulting in the synchronous generators to go out of step and lose synchronism.Due to the importance of the power system and its stability, there are several techniques developed by various researchers for the stabilization of the power systems. The paper addresses enhanced Artificial Bee Colony ABC technique applied to design a robust power system stabilizer PSS in order to improve transient and dynamic stabilities of a turbo alternator connected to an infinite bus system comparisons wind, thermal and solar power generations the design of the proposed controller initially is formulated as an optimization problem and then enhanced ABC is employed for obtaining optimal controller parameters. The results shows that the proposed algorithm are better in performance than the conventional methods.
