Study on Primary Frequency Control of Power Grid Based on Flywheel Energy Storage Technology

Jun Li

Abstract

Abstract The frequency regulation of power grid is the most valuable application direction of energy storage technology in the auxiliary services field. Through the analysis and comparison of different energy storage technologies, the energy storage principle of flywheel energy storage (FES), the design of motor controller and capacity selection method of FES system are introduced and analyzed in detail. With its strong short-time power capacity and easy change of adjustment direction, combined with conventional frequency modulation technology, it can be used as an effective auxiliary means of primary frequency control (PFC) to ensure grid frequency stability.
