Smart Grid

  1. 1. INTRODUCTION
  2. 2. Nowadays, the electric power system is facing a radical transformation in worldwide with the decarbonise electricity supply to replace aging assets and control the natural resources with new information and communication technologies (ICT). A smart grid technology is an essential to provide easy integration and reliable service to the consumers. A smart grid system is a self-sufficient electricity network system based on digital automation technology for monitoring, control, and analysis within the supply chain. This system can find the solution to the problems very quickly in an existed system that can reduce the workforce and it will target sustainable, reliable, safe and quality electricity to all consumers.
  3. 3. The smart grid can be defined as a smart electrical network that combines electrical network and smart digital communication technology. A smart grid has capable of providing electrical power from multiple and widely distributed sources, like from wind turbines, solar power systems, and perhaps even plug-in hybrid electric vehicles.

  5. 5. SMART GRID COMPONENTS
  6. 6. To achieve a modernized smart grid, a wide range of technologies should be developed and must be implemented. These technologies generally grouped into following key technology areas as discussed below. Intelligent Appliances: Intelligent appliances have capable of deciding when to consume energy based on customer pre- set preferences. This can lead to going away along toward reducing peak loads which have an impact on electricity generation costs. For example, smart sensors, like temperature sensor which is used in thermal stations to control the boiler temperature based on predefined temperature levels.
  7. 7. Smart Power Meters: The smart meters provide two-way communication between power providers and the end user consumers to automate billing data collections, detect device failures and dispatch repair crews to the exact location much faster. Super Conducting Cables: These are used to provide long distance power transmission, and automated monitoring and analysis tools capable of detecting faults itself or even predicting cable and failures based on real-time data weather, and the outage history.
  8. 8. Integrated communications: The key to a smart grid technology is integrated communications. It must be as fast as enough to real-time needs of the system. Depending upon the need, Many different technologies are used in smart grid communication like Programmable Logic Controller (PLC), wireless, cellular, SCADA (Supervisory Control and Data Acquisition), and BPL. Key Considerations for Integrated Communication. Phasor Measurement Units (PMU): This is used to measure the electrical waves on an electricity grid using a common time source for synchronization. The time synchronizer allows synchronized real-time measurements of multiple remote measurement points on the grid.
  9. 9. Smart Substations: substations are included monitoring and control non-critical and critical operational data such as power status, power factor performance, breaker, security, transformer status, etc. substations are used to transform voltage at several times in many locations, that providing safe and reliable delivery of energy. Smart substations are also necessary for splitting the path of electricity flow into many directions. Substations require large and very expensive equipment to operate, including transformers, switches, capacitor banks, circuit breakers, a network protected relays and several others.
  10. 10. ADVANTAGES OF SMART GRID
  11. 11. • The smart grid has been able to provide better power management technologies through its integrated systems, providing with a better user interface. • It has also provided with a protective management system in case of emergency crisis or setbacks. • It has been in understanding that smart grids provide with a better supply and demand management. • The smart grid has not only provided with longer battery timing but also with better power quality to its consumers.
  12. 12. • Previous grid stations used to emit a large amount of carbon dioxide which in this case has been terminated at all. • It has also provided with the convenience of reading meters remotely. Meter readers will not have to physically appear at the property and check for meter readings. It will all be done through IT resources.
  13. 13. DISADVANTAGES OF SMART GRID
  14. 14. • Privacy Problems The biggest concern is Security in a smart grid system. Grid system uses some smart meters, which are automated and provides communication between power provider and customer. Here some type of the smart meters can be easily hacked and they may control the power supply of a single building or an entire neighborhood.
  15. 15. • Grid Volatility Smart Grid network has much intelligence at its edges; that is, at the entry point and at the end user’s meter. But the grid has insufficient intelligence in the middle, governing the switching functions. This lack of integrated development makes the grid a volatile network. Engineering resources have been poured into power generation and consumer energy consumption, which are the edges of the network. However, if too many nodes are added to the network before developing the software intelligence to control it, the conditions will lead to a volatile smart grid.
  16. 16. SMART GRID APPLICATIONS
  17. 17. The addition of digital technology into the grid system has revolutionized its working in an un-imaginary way. It has not only transformed the way power stations used to work but it has also provided an upper hand to the consumer market in reliability, efficiency, and accessibility regarding electricity.
  18. 18. Some of its applications are as follows: • Improving the working of transmission lines. • Quick repairing system after any sort of breakage or misfire. • It will also reduce the cost of electricity. • Reducing the peak demand.
  19. 19. CONCLUSION
  20. 20. Smart grids have revolutionized the energy system with a big leap. It has not only made it faster but way more reliable and efficient by means of generating electricity. People have been able to get easy access to electricity and a smarter way to lodge complaints in case of an issue. It has brought about many necessary changes in the world of producing energy and has improved the living standards of the people by all means.
