Abstract

Abstract: In view of the problems of capacity ratio, point selection of grid-connection and electricity market interest game, this paper, by taking the system power balance, physical constraints, dynamic reactive power support capability and the frequency and voltage characteristics as constraint conditions, uses the classical Newton-Raphson method and quadratic programming method to develop a multi-objective function which takes into account of power generation cost, grid loss, and the benefit of wind power and PV yield. By taking IEEE30, IEEE57 nodes as an example, the optimization planning scheme of wind-solar complementary is obtained by simulation. The calculation result proves the validity of the proposed model. It is proved that the balance of interests and the maximization of objective function can be achieved in the scenario of grid-connection at the large load node and wind-solar power ratio closing to its unit cost ratio.

Key words: wind-solar complementary, multi-objective, active distribution network, quadratic programming, output ratio
