Island photovoltaic storage microgrid as the main source of electric energy for electric ship charging station,its capacity configuration is affected by the uncertainty of electric ship demand.The paper proposes an optimal capacity configuration method for the island photovoltaic storage microgrid system with electric ship charging station.Firstly,the power demand of the electric ship charging station is analyzed combined with the energy consumption characteristics of the electric ship.Then comprehensive economic cost minimization is regarded as an objective function to establish a robust optimization model for the capacity configuration of the island photovoltaic storage microgrid considering the uncertainty of the energy consumption of the electric ship.Finally,the effectiveness and rationality of the model are verified by simulation experiments.The results show that the microgrid capacity allocation scheme obtained by the proposed model can effectively ensure the power supply of the electric ship,and the choice of the scheme is related to the preference of decision-makers for the energy supply reliability and economic cost.
