Abstract. The concept of frequency regulation for a multi-microgrid (MMG) model is investigated in this paper. The MMG consists of various distributed generators and energy storage units. In this paper, a hybrid energy storage model comprising battery energy storage unit (BESU) and superconducting magnetic energy …
Frequency regulation is mainly provided by ramping (up and/or down) of generation assets. This typically takes minutes rather than seconds. Electricity storage has the capability for doing the job in milliseconds, and Pacific Northwest National Laboratory (PNNL) has suggested millisecond electricity storage should have a value of at least …
Exploiting energy storage systems (ESSs) for FR services, i.e. IR, primary frequency regulation (PFR), and LFC, especially with a high penetration of intermittent RESs has recently attracted a lot of attention both in academia and in industry [12, 13].
