摘要
针对大量光伏电源并网可能引起电压越限的问题,通过分析接入光伏电源后对配电网所造成的影响,综合考虑光伏电源渗透率最高、损耗最小、电压治理最佳等多目标优化的要求,建立计及源荷匹配特性的光伏电源配置优化数学模型。同时,提出基于个体适应度评价原则和协同分解准则的双准则差分进化算法,并通过该算法解决目标值的分布问题,提高目标空间的收敛能力。算例分析结果表明,所提方法能够压缩9%以上的配置成本,具有更高的准确性及实用性。
There is a problem that a large number of photovoltaic power supplies are connected to the grid,the voltage may ex-ceed the limit.Therefore,this paper analyzes the impact on the distribution network after photovoltaic power supply is con-nected,and comprehensively considers the requirements of multi-objective optimization such as the highest penetration rate,the lowest loss and the best voltage governance of photovoltaic power supply,and then a mathematical model of photovoltaic power supply configuration optimization taking into account the source load matching characteristics is established.A double criteria differential evolution algorithm based on the individual fitness evaluation principle and the cooperative decomposition criterion is proposed to solve the distribution problem of the target value,and improve the convergence ability of the target space.The re-sults of an example show that the proposed method can reduce the configuration cost by more than 9%,and has higher accuracy and practicability.
