文摘

High penetration of renewable energycauses fluctuationsof power flow and results in system frequency fluctuation, which significantlyaffects the power system operation. The situation in microgrid (MG) is worse because of the low inertia and small time constant of the system. This paper present a novel use ofthesuperconducting magnetic energy storage (SMES) and battery hybrid energy storage system with the function of frequency control in the MG.A hybrid power management strategy for the SMES and the battery is used to achieve, firstly, a faster primary frequencycontroland secondly, an improvement of battery service time.
