Frequency Control Strategy of Hybrid Energy Storage System for Autonomous Microgrid Based on Frequency Hysteretic Loop
摘要
Abstract
In this paper,a frequency control strategy of hybrid energy storage system(HESS)including battery and su⁃percapacitor for autonomous microarid(AMG)based on frequency hysteretic loop is proposed. The control strategy is composed of two modes.ControlⅠcoordinates the relationship between the frequency control precision and the battery charge/discharge cycles by utilizing the proposed frequency hysteretic loop,thus reduces the charge/discharge times. Considering the dual constraints from battery lifetime and the supercapacitor capacity comprehensively ,ControlⅡcoor⁃dinates the charge/discharge priorities of battery and supercapacitor to achieve an optimal control of different energy storage devices in the HESS.Finally,a Benchmark low voltage AMG is established in DIgSILWNT as test system,and the simulation result verifies the effectiveness of the proposed control strategy .关键词
