Abstract

The distribution network has inherent characteristics of long supply radius and complex structure. With the increasing of strong wave from load and DGs, the uncertainty of distribution network power flow is also increased and might causes the voltage quality deterioration in the distribution network. Therefore, it is necessary to rationally configure the DSTATCOM to improve the economic benefit of distribution network, ensure the voltage quality, and improve the DG accommodation. In this paper, a multiobjective coordinated optimization method are proposed for the DSTATCOM configuration and its setting in distribution networks, which considers the operation of DSTATCOM and the parameters setting problem in the process of optimal configuration. For distribution networks with DG, the optimization model of target system involves losses, a total investment of equipment, equipment idle rate and abandoned power generation of DG. The Pareto solution sets are obtained based on the NSGAII, and the weighted ideal point method is employed for decisionmaking. The outstanding characteristic of those methods is that it considers the configuration and operation of the DSTATCOM synthetically and the proposed method is verified by the example of IEEE33 bus sample system.
