Abstract Traditional dispatch or control method will suffer great difficulty with large scale integration of plug-and-play distributed generators in the power systems. The distributed control method can mitigate the burden of the power systems with distributed generation. In this paper, a continuous-time projection gradient algorithm based optimal dispatch method is proposed to improve the effectiveness of distributed control method for distributed generation. The proposed method does not rely on the known total load of the power system and the artificial initial value of state variables which are used widely in the consensus-based control methods, but only the projection operator is used to constrain the output of the distributed power supply, which can automatically run to the optimal point of the economic dispatch, thus significantly improving the practicability of distributed control method. Case study verifies the effectiveness of the proposed method.
