摘要: 电力弹簧(electric spring, ES)作为需求侧响应的一种新技术已经成为电力行业研究的热点。为充分发掘ES潜力,文章提出基于人工鱼群算法(artificial fish swarm algorithm, AFSA)的新型ES多目标电能质量优化控制策略,实现关键负载(critical load, CL)的电压、系统频率和非关键负载(non-critical load, NCL)功率因数的优化。首先提出一种新型背靠背型电力弹簧(back-to-back electric spring, B2B-ES)拓扑结构,实现负载侧供电侧功率双向流动稳定NCL电压范围。其次提出加权平均视觉范围和自适应拥挤度因子的改进AFSA,设计多目标优化函数提取负载侧NCL的电压值和系统频率等本地信息优化ES的控制信号,通过在线调整电力弹簧的补偿功率改善系统电能质量。经仿真验证,文章所提优化控制策略能够克服现有ES控制方法目标单一、实时性差的缺点,实现多目标电能质量实时优化。

Abstract: Electric spring (ES), as a new technology for demand-side response, has become a hot issue in the power industry. In order to fully exploit the potential of ES, this paper proposes a multi-objective power quality optimization control strategy for novel ES on the basis of AFSA to optimize the voltage of critical load (CL), system frequency and power factor of non-critical load (NCL). Firstly, a new back-to-back electric spring (B2B-ES) topology is proposed to realize bidirectional flow of power on the load side. Secondly, an improved artificial fish swarm algorithm (AFSA) is proposed, which is based on the weighted average visual range and adaptive crowding factor. The multi-objective optimization function is designed to extract the local value of the load-side NCL voltage and system frequency to optimize the ES control signal, so as to compensate the power quality of the system online by adjusting the power of the electric spring. Finally, the simulation proves that the proposed optimization control can overcome the shortcomings of single-objective and poor real-time performance of the existing ES control method, and realize real-time optimization of multi-objective power quality control.

Key words:  electric spring (ES), back-to-back (B2B) structure, multi-objective power quality optimization, artificial fish swarm algorithm (AFSA )
