Optimal Control Strategy and Capacity Planning of Hybrid Energy Storage System for Improving AGC Performance of Thermal Power Units
摘要
Abstract
By taking the hybrid energy storage system(ESS)composed of the value regulated lead acid(VRLA)battery and the vanadium redox battery(VRB)as an example,in view of the intrinsic characteristics of conventional unit frequency regulation, a charge and discharge strategy and optimal capacity planning of hybrid ESS participating in the automatic generation control (AGC) by assisting conventional units is studied.Firstly,according to the characteristics of conventional unit frequency regulation, an optimal control strategy taking into account the suppression of reverse frequency regulation, dead zone oscillation,ESS over discharge,and forced state of charge (SOC) homing is proposed.Secondly,considering the cost of ESS configuration and the frequency regulation income of power generating units,a capacity planning model is developed.Finally, based on the particle swarm optimization(PSO) algorithm,the simulating calculation of the actual operation data of a power station is conducted.The results show that the frequency regulation performance and the running cost of the method are both better than those of the conventional unit frequency regulation.关键词
