Design of Energy Storage Management System with Multiple Constraints in Distributed Microgrid

Abstract

The energy storage system in distributed microgrid is the core of maintaining the stable operation of microgrid, and its control strategy has great optimization space. Aiming at the problem that the traditional single-constraint control method of energy storage management system has a low fault-tolerant rate in microgrid, which can cause the fluctuation of microgrid, this paper puts forward a multi-constraint control algorithm (SOC, Power, control strategy, SPC), which bases on battery running constraint, microgrid power constraint and microgrid control constraint. Finally, the energy storage system model is established by MATLAB software, and the net load power of the microgrid is selected as the input of the traditional single and the SPC multi-constrained energy storage system, the output is the dynamic power of the microgrid. The simulation results show that the SPC multi-constrained algorithm can effectively improve the utilization rate of energy storage system and reach the effect of peakfilling and valley filling.
