摘要
为在配电网中优化配置分布式电源(distributedgeneration,DG),基于"局部–全局–局部"思想首先构造功率圈,借助物理学质心概念,搜索静力矩平衡点配置DG;然后从全局考虑含多DG网络节点电压要求,结合节点电压波动指标对DG接入点进行区域修正,并校验功率圈内电压约束条件是否满足要求;最后解析独立DG等效网络,计算有效传递(影响)因子,为进一步的区域DG优化调度提供参考。算例结果验证了该方法的有效性。
To optimally configure distribution generations （DGs） in distribution network, at first, according to the thinking of ＂firstly from the local to the global, then from the global to the local＂, the power circle is constructed and by means of the concept of centroid in physics the equilibrium point of static moment is searched to configure DGs; then the requirements of nodal voltages of distribution network, which contains multi DGs, are overall considered and by means of the index of nodal voltage fluctuation, the regional correction of the points where DGs connect to distribution network is performed, and it is verified that whether the required voltage constraints within the power circle are met; finally, build the equivalent network of independent DG and calculate active transfer （impact） factor to offer reference for further regional optimal dispatching of DGs. The effectiveness of the proposed method is verified by calculation results of IEEE 33-bus system.
