英文摘要	This paper focuses on frequency regulation and the economic dispatch problems of microgrid primarily composed of multi energy resources. Due to different problems such as intermittency of renewable energy, unbalanced demand and supply, frequency fluctuation and so on in microgrid. These problems alternative stability and disturbance rejection present challenges to the design of controllers and management algorithms for voltage, frequency and power in all possible execution scenarios. In this work, a novel adaptive generalized distributed averaging integral controller has been designed. Goals of the designed controller are to realize accurate steady-state frequency recovery in the circumstances of clock drifts, cope with the uncertainty by dynamically updating of the control parameters while maintaining system stability, exchange generating data of each generator by the communication channel and, realize the optimal power distribution among the generators. Moreover, we add an additional controller to the hierarchical control scheme to distribute the load economically, the algorithm based on consistency ensures the optimal load distribution. Finally, the effectiveness of the designed control scheme is verified by simulation comparing it with other related distributed control methods. © 2022 The Authors
