中文摘要: 根据分布式光伏发电特性，通过对中压配电网中无功优化的分析，找到潮流、电压波动和无功容量与光伏发电无功功率间的定量关系。利用粒子群优化（PSO）算法，基于逆变器的分布式光伏发电中压配电网的无功优化，明确了控制无功功率以支持配电网和电压调节的方法。实例仿真结果说明，该方法能够有效减少光伏发电系统中压配电网的电压升高和逆潮流问题。
Abstract:According to the characteristics of distributed PV generation,and reactive power optimization in medium voltage distribution network is analyzed,and the quantitative relationship between the PV reactive power of the tidal current,voltage fluctuation and reactive power capacity is established.PSO algorithm is introduced based on distributed PV inverter of medium voltage distribution network reactive power optimization method,to make clear about the control of reactive power in support of the distribution network and the method of voltage regulation.The simulation results show that the proposed method can effectively reduce the voltage rise and tide reversal problems of the voltage distribution network in the PV generation system.
