Abstract

Abstract: This paper firstly analyzes the problems faced by island power supply， and the feasibility using microgrid group for island power supply. The concept of energy exchange station （EES） and topology of microgrid based on EES is proposed. The calculation method of microgrid power shortage under different control strategies is given and an adaptive control strategy for EES-based island microgrid group is proposed. A simulation model was built in MATLAB/Simulink to simulate two different operating conditions of EES. The simulation results show that the topology and its control strategy can effectively realize the energy transmission among micro network groups with different control strategies， and improve the utilization of island energy.

Key words: island power supply, microgrid group, energy storage capacity, energy exchange station
