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.

How does IREMS work?
The objectiveis 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 strategyis to minimize the daily cost by making use of the difference among electricity prices and the flexibility of the microgrid elements.
DataTo 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)
ExecutionThe Optimization Module runs every 15 minutes.
How does IREMS work?Energy management relies on two steps2Energy Balance (Real Time Module)
The objectiveis to ensure the power balance for all elements in the microgrid and to send the set-point to each controllable component.
The strategyIf 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.
DataTo perform this operation, the following information is used:
•Microgrid configuration.•Optimization Module results.•Real time measurements and status.
ExecutionThe Real Time Module runs every 3 seconds.
Demand Generation
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 market

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.

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

ResponsibilityCA 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.).
Applications and advantages of the CA
Easier to forecast
consumption and
flexibility
Consumers deal with
only 1 agent instead of 2
Less contracts and less
connections
Contracts easier to handle.
Billing is easier
More efficient
solutionsValidation of flexibility ProductsTo validate flexibility products prior to its activation, when used by other agents different to the DSO itself.
