A distributed optimal control method for active distribution network

This paper presents a distributed optimal control method for stable and economical operation of active distribution network (ADN). The method incorporates a distributed constraint optimization problem (DCOP) model with distributed simulated annealing (DSAN) algorithm based on potential game. Moreover, the distributed optimal strategy is developed on the basis of multi-agent system, and the distributed power flow calculation method is utilized to perform the power flow calculation among agents. The performance verification of the distributed optimal control strategy and the comparison with the centralized method are conducted in IEEE 39-bus system with distributed generations (DGs). Finally, the simulation cases are presented and discussed to demonstrate the effectiveness and applicability of the proposed optimal method for ADN.
