Microgrids as energy and flexibility providers for TSO-level networks

In the future, the utilisation of technical services from distribution network connected flexible energy resources will be increasingly needed. Microgrid (MG) typically has multiple different flexible resources like distributed generation units, battery energy storages, electric vehicles and controllable loads. Therefore, MGs can be also seen as flexible resources from the power system point of view. This study will present a new method to adopt the flexibility of MGs for transmission network needs. Therefore, an MG aggregator is proposed to be responsible for scheduling several MGs with various resources aiming to participate in the transmission system operator (TSO)-level energy and flexibility markets. The results of the scheduling and different market participation of the MGs are simulated for the hypothetical MGs in Finland and the results will be discussed as well.
