Study on influence of DG access on network loss in copper mining area based on improved Newton method

铜矿区配电网中分布式电源的接入使得系统结构变得复杂,且电流方向灵活不确定,对铜矿区网损具有剧烈影响。文中介绍了PQ、PI、PV、P-Q(V)在潮流计算中的处理方法。通过IEEE34节点系统为例,从分布式电源接入配电网的容量、位置出发设定了不同方案以研究不同接入情况下对铜矿区配电网网损的影响,做出理论分析。

The distribution of the distributed power in the distribution network of copper mine area makes the system structure complicated and the current direction flexible and uncertain, which has a severe impact on the network loss in the copper mining area. The methods of PQ, PI, PV and P-Q（V） in power flow calculation are introduced in this paper. Through the IEEE34 node system as an example, the influence of the loss of copper mine distribution network set up with different solutions to different situations of access from the distributedgenerations capacity and position, make the theoretical analysis.
