Multi-objective Optimal Allocation of Reactive Compensation and OLTC in Active Distribution Network

为应对主动配电网潮流波动,提升主动配电网运行经济性和安全性,以投资成本、网损、电压偏移最少为目标,建立了投资层与多时段模拟运行层一体化的多目标优化配置模型。同时,为进一步决获取符合实际需求的最优配置方案,提出动态加权的多目标求解方法,得到最优解集。通过仿真算例验证了所提方法的有效性。

In order to cope with the power flow fluctuation of the active distribution network and improve the economy and security of the active distribution network operation,a multi-objective optimal configuration model integrating the investment layer and the multi-period simulation operation layer is established with the goal of minimizing the investment cost,network loss and voltage offset.At the same time,in order to further determine the optimal allocation scheme that meets the actual needs,a dynamic weighted multi-objective solution method is proposed to obtain the optimal solution set.The effectiveness of the proposed method is verified by a simulation example.
