Coordinated control strategy of distributed generation based on active distribution network under multi-time scales

Active distribution network is an effective way to realize the integration of distributed new energy sources in the future. This paper focuses on the coordinated control framework of multi-time scales distributed generation for active distribution network under normal operating conditions, including scales for a long time in active distribution network the optimization control and short time scaleactive distribution network of regional autonomy for control. On this basis, a global optimization algorithm based on optimal power flow is proposed, and a regional autonomous control algorithm for active power distribution network based on power control error is proposed. Through simulation examples to verify the time of active distribution network coordinated control technology of self tendency ute and for the effectiveness of real-time scheduling of distribution network active.
