【摘要】：为解决配网系统中因三相不平衡造成的三相电压不对称、配电变压器出力降低、网络损耗增加等一系列问题,通过综合考虑配网系统中各节点的负荷曲线特征,建立长效三相平衡优化换相模型,弥补了常规基于单个时间点负荷换相模型需要频繁换相的不足;然后,提出一种基于分子动力学原理的新型模拟结晶算法求解模型,以在进化后期获得更高的个体多样性,从而可有效避免陷入早熟,快速求得全局最优换相方案;最后,通过对IEEE 34节点配电系统进行三相平衡优化换相计算,验证了所提方法的有效性及优越性。
[Abstract]:In order to solve a series of problems such as the asymmetry of three-phase voltage caused by three-phase unbalance, the decrease of distribution transformer's output force and the increase of network loss in distribution network system, the characteristics of load curve of each node in distribution network system are considered synthetically. A long-effect three-phase equilibrium optimal commutation model is established, which makes up for the need of frequent commutation based on single time point load commutation model. Then, a novel simulated crystallization algorithm based on molecular dynamics is proposed to solve the problem. In order to obtain higher individual diversity in the later stage of evolution, so as to avoid falling into precocity effectively, the global optimal commutation scheme can be obtained quickly. Finally, the three-phase equilibrium optimal commutation calculation for IEEE 34-bus distribution system is carried out. The effectiveness and superiority of the proposed method are verified.
