Abstract:
This paper proposes a model for an aggregator of energy management systems (energy box aggregator - EBAg) to operate as an intermediary between individual energy management systems (local energy boxes) and the System Operator / Energy Market capable of facilitating a “load follows supply” strategy in a Smart Grid context. The EBAg is aimed at using the flexibility provided by end-users of demand-side resources to respond to system service requirements, via contracts, involving lowering or increasing the energy consumption in each time slot. The aim is contributing to the balance between load and supply, avoiding peaks in the aggregate load diagram, and coping with the intermittency of renewable sources. For this purpose an optimization model for the EBAg has been developed, which is tackled using a genetic algorithm based approach to deal with the combinatorial characteristics of the model.
