含分布式电源的配电网络重构

随着分布式电源在电力系统的逐步推广,考虑分布式电源的配电网重构具有广阔的发展前景。提出基于Metropolis准则的群搜索优化算法,并对含分布式电源的配电网进行重构。Metropolis准则能够有效解决发现者局部寻优时产生错误的搜索方向,从而跳出局部极值点,提高了优化的效果。算例结果表明分布式电源的引入提高了节点电压,降低了有功网损,并验证了算法的可行性。

The reconfiguration of distribution network with distributed generation

With the widespread of the distributed generation in the power system,the distribution network reconfiguration with the consideration of distributed generation has broad development prospects.A new group search optimizer algorithm is proposed based on Metropolis standards,and is used to reconstruct the distribution network with the integration of distributed generations.Metropolis standards can effectively resolve the problem that leads to a wrong search direction when local optimization is found.Thus program can jump out of the local extreme value point and better optimization effect is obtained.Test results show that the introduction of the distributed generation increases nodal voltage,and reduces the active network loss.Test results verifies the feasibility of the proposed algorithm.
