摘　　要：随着分布式光伏并网的增多,基于放射状运行的中压配电网成了多源网络,这样传统的配网联络开关设置方法就需要进行改进。文章通过对光伏出力的等效变换,将其融合进配网负荷曲线中,然后模拟积分中值定理对新的负荷曲线进行合理区间划分,以此划分结合一系列电气量约束、网络拓扑约束、开关操作次数约束等,寻求线路运行损耗最小和停电损失最少。这就是考虑分布式光伏接入的配网联络开关优化布置方法。算例结果表明,文章提出的方法是有效的,值得进一步推广。With increased network distributed PV, radial run-based medium voltage distribution network has become a multi-source network, so the traditional distribution network contact switch setting methods need to be improved. Through the equivalent output of photovoltaic conversion, which is integrated into the distribution network load curve, and then simulate integral value theorem for the new load curve reasonable interval division, this division with a series of electrical capacity constraints, network topology constraints, the number of switching operations constraints, seek lines running minimum loss and minimum power loss. This is to consider access to the distribution network of distributed photovoltaic contact switch arrangement optimization methods. Numerical results show that the article proposed method is effective and worthy of further promotion.
