What is IREMS?
IREMS is an Energy Management System developed by IREC.
IREMS is able to optimally manage several kind of generators, loads
and storage units under a common goal: to make more cost-effective
and efficient your Microgrid.
IREMS is a gateway between a Microgrid and an external agent such as
Commercial Aggregator.

6. How does IREMS work?
The objective
is to calculate the optimal energy
planning of power consumed or
generated by every unit in the microgrid
within a 24-hour scope.
Energy management relies on two steps
1
The strategy
is to minimize the daily cost by making
use of the difference among electricity
prices and the flexibility of the microgrid
elements.
Data
To perform this operation, the following
information is used:
•Microgrid configuration and current status.
•Real time measurements.
•Weather forecasts (wind speed, solar
irradiance, temperature).
•Demand forecasts.
•EV mobility forecasting.
•Energy price.
Energy Planning (Optimization Module)
Execution
The Optimization Module runs every 15 minutes.
7. How does IREMS work?
Energy management relies on two steps
2Energy Balance (Real Time Module)
The objective
is to ensure the power balance for all
elements in the microgrid and to send the
set-point to each controllable component.
The strategy
If there is any deviation, this module
carries out adjustments over the
preliminary set-points calculated by the
Optimization Module until to achieve the
energy equilibrium.
Data
To perform this operation, the following
information is used:
•Microgrid configuration.
•Optimization Module results.
•Real time measurements and status.
Execution
The Real Time Module runs every 3 seconds.

8. External interfaces
• Responsible for the proper operation of IREMS
• Control the access of other actor to IREMS.
• Have total information access.
• Remotely interact with IREMS through a thin client with a
Graphical User Interface (GUI).
• Owns one power unit or more in the microgrid.
• Able to access to some information of the element that (s)he
owns.
• Able to modify some parameters.
• Remotely interact with IREMS through a thin client with a GUI.
• Requests measurements and forecasts of the microgrid
• Limit total power consumed/generated by the microgrid.
• Remotely interact with IREMS through a thin client with a
GUI.

What advantages does IREMS offer?
Possibility of operation using the IREMS
user interface fully integrated into the
client system.
IREMS is able to automatically manage
energy supply, demand and storage at real
time.
• It is able to manage the monitored data from
grid-connected systems.
• It is able to decide the optimal behaviour of
the systems at real time based on advanced
optimization algorithms.
•The final user can choose among different
modes of operation:
cost minimization
environmental footprint
peak shaving, among others.
Different types of users with different
levels of permissions and access
Competitive advantages over other products on the

What advantages does IREMS offer?
Advantages for the different agents/clients
In case they incorporate the
product to their building
management company, they
will receive a large share of the
benefits.

IREMS
Management of local demand
and supply will enable
renewable sources penetration
as well as the decrease of peaks
in the demand curves.
That will defer investments
required for grid
reinforcements and consequent
grid losses.
Societal and environmental
benefits from energy efficiency
are well-known including GHG
emission abatement.
They will be able to
incorporate this tool to their
existing solutions and
equipment to add the real time
control and optimization layer.

Commercial Aggregator Concept
Main role of the Commercial Aggregator (CA) is
to gather flexibility products from its
prosumers portfolio, who do not have the size
to trade directly into wholesale markets, and to
optimize its trading in electricity markets
aiming to maximize its profits.
This new agent would provide direct revenue to the businesses and
homeowners, besides ensuring higher stability and efficiency in the grid
Commercial Aggregator is the key mediator between the consumers
and the markets and the other electricity system participans
Key enabler of “FLEXIBILITY”
17. • To simulate the behaviour of the
average consumers under different
price and volume signals.
• To obtain the aggregated response for
the whole clusters.

Responsibility
CA are totally responsible for their own
imbalances, so they will have to deal with their
own energy paybacks when participating in
wholesale markets
Commercial Aggregation is considered as a key innovation on the power system to
face future challenges posed by growing demand and RES integration
Procurement of flexibility products
The DSO can access and procure flexibility
products offered by commercial aggregators to
use them for a number of purposes (e.g.
distribution network reinforcement deferral,
congestion management, etc.).

Consumption Forecasting
Consumption forecast will be used for estimating the consumption baseline. A baseline is important to calculate the effective service provided by the aggregation service provider and to avoid strategic users from being incentivized to emphasize their individual benefits without real gain for the system
Consumer Segmentation (Clustering)
Since every cluster consists of prosumers having a similar behaviour, an average one per cluster may be assumed. Then, incentive policies and their results may be simplified by simulating the average consumer of every cluster.
Flexibility Forecast Tool
The algorithm is run for an average consumer from every cluster. Thus, after forecasting the response of this average consumer, the aggregated response for the whole cluster can be obtained.
Market forecasting
To forecast the market price of the sold and purchased electricity.
These methodologies rely on statistical and financial analyses of the markets where CAs participate.
The Commercial Optimal Planning Tool
To calculate the optimal incentive and bidding policy, in order to maximize the profits of the Commercial Aggregator.
