考虑网损及经济性的综合源储优化及电池容量设计
摘要:Wind power output is characterized by intermittensity and instability, and distributed wind power is offen difficult to meet load demand independently, and the wind curtailment rate is high. Therefore, wind power, small hydropower and energy storage batteries are connected to the distribution network at the same time to ensure the stability of the system and reduce the wind curtailment rate of the system. Firstly, the access positions of wind power and small hydropower are calculated with the goal of minimizing the network loss, and verified by PSASP software. Then, the voltage offsets of access nodes are measured by Matlab software. Secondly, the access position of vanadium redox battery (VRB) is obtained with the goal of minimizing the network loss. Then, the multi-objective function is constructed by considering the total cost and air abandon volume. The optimized function is obtained by using the improved hybrid based particle swarm optimization algorithm. Finally, the IEEE 36-node system and the actual wind and hydropower farm data in a certain area are used to verify the effectiveness of the proposed method. The simulation results show that the proposed method can reduce the wind curtailment rate of wind power, maintain the stability of the system, meet the demand of users, and meet the economic requirements.
