Abstract: Aiming at the slow convergence rate of decentralized control, a distributed control strategy of microgrid was proposed based on the decentralized–distributed control concept. The optimal operation point of microgrid was realized in a fast convergence speed under communication constraints using consensus algorithm. Distributed generators can be operated in fully dencentralized mode or decentralized distributed mode. Simulation results indicate that the proposed distributed consensus algorithm is effect and that communication delay and communication failure only have a small impact on this control strategy.

 

Key words: microgrid; distributed control; consensus algorithm; communication delay
