Multi-Objective Transmission Network Planning with Consideration of Power Grid Vulnerability and Wind Power Accommodation

By Chun-guang Tian, Xiang-yu Lu, Li-sen Chu, Tian Dong and De-xin Li

Abstract

This paper proposes an efficient approach for transmission network expansion planning. Three indicators are proposed to\ud evaluate the planning, which is the power grid vulnerability, wind power accommodation and operation cost.\ud Vulnerability is evaluated based on the complex network theory, and wind power accommodation analysis is performed\ud by the rate of abandoned wind power. The optimization of transmission network expansion planning is translated into\ud constraints multi-objective optimization problem. A novel QS-MOWE algorithm based on the improvement quick sort\ud and NSGA-II algorithm has been proposed. The method can be used effectively to study the effect of increasing wind\ud power integration and vulnerability with high wind generation uncertainties. The model and algorithms are applied to\ud calculate a case of 6 units. The results show that the proposed modeling method can provide a useful guidance for\ud planning problems
