分布式电源配置研究

Research on Distributed Power Configuration

分布式电源的引入改变了配电网的结构,对配电网的网络损耗有很大的影响,需要对分布式电源进行合理配置。针对单支路馈线模型在3种负荷类型下,同时考虑分布式电源接入位置和接入容量2个因素,以最小化馈线损耗为目标提出了分布式电源配置的方法;针对网状系统,提出了一种新的基于节点有功功率网损灵敏度的单DG配置算法,并利用算例仿真验证了算法的可行性。结果表明,这些方法可更加高效精确地实现分布式电源的最优配置。

The introduce of distributed generation changes the structure of the distribution network, which impacts on the network losses of distribution, so a rational configuration of distributed power is needed. In allusion to single feeder model with three types of loads, the location and the capacity of distributed power are taken into consideration, and a method of distributed power configuration for the smallest loss is proposed. For the reticulation system, a new method is put forward for single DG configuration based on the sensitivity of node active power network loss and the simulation results show the feasibility of the method. The results show that these methods can achieve the optimal configuration of distributed power more efficiently and accurately.
