摘要
To maintain energy balance and voltage stability is the basic function for normal operation of DC grid. Analysis and comparison of several commonly used multi-point voltage control methods, a cooperative control strategy is proposed based on improved particle swarm optimization, considering economic performance and voltage quality in both. The method established on traditional multi-point voltage control, using fuzzy membership curve to transformed power loss and voltage deviation into a single optimization objective, then search the optimal stable operating point of grid by PSO algorithm with inertia weight. Finally, a six terminal dendriform DC grid system is simulated to contrast the proposed method to voltage droop control. Results verify the effectiveness and practicability of the proposed algorithm.
