Microgrid (MG) is proposed to integrate the distributed generations and improve the energy efficiency. Economic dispatch is an important tool to obtain the economic operation in MG, which deals with the power in efficient ways while meeting the constraints of total load demand as well as the generator constraints. In research, a two-layer MG is proposed, where the top layer is a communication network for information transmission, while the bottom layer is the MG for power transmission. A fully distributed control method is proposed to obtain the minimum operation costs of the distributed generations by reaching the consensus of the incremental cost, which can address the equality and inequality constraints. Then, seven cases are designed to evaluate the performance of the methods. The simulation results demonstrate the effectiveness of proposed approach.
