Extended Planning of Wind Power Coordinated Transmission Network Based on Discrete Multi-objective Dragonfly Algorithm and Improved FCM

In the light of expansion planning of wind power coordinated transmission network， the scheme based on discrete multi-objective dragonfly algorithm and improved FCM is proposed. Firstly， the multi-objective wind power coordinated transmission network expansion planning model is built with the investment and construction cost，network loss cost and abandoned air volume as indicators. The weighted multi-core improved FCM algorithm is designed which effectively simulate the spatial distribution of wind power in multi-dimensional operation. Then， the flexible N-1 safety verification strategy is proposed to screen out the extreme scenarios with low membership，large output and load. The discrete multi-objective dragonfly algorithm is designed to improve the accuracy of multi-objective optimization. Finally，the extended planning model of wind power coordinated transmission network is solved by using the discrete multi-objective dragonfly algorithm，and the optimal planning strategy is proposed. Simulation results show the effectiveness of the proposed method.
