Abstract

Extreme scenarios are important factors that threaten the economic and stable operation of isolated island microgrids. Taking into account the economic cost of system operation and the constraints on stable operation under extreme scenarios

a method for optimizing the capacity allocation of isolated island microgrids is proposed. First

a two-stage isolated island microgrid energy storage capacity optimization and allocation mathematical model is proposed

with the upper and lower layers constructing the system capacity optimization and allocation model and the operation benefit optimization model

respectively

and the stable operation constraints under extreme scenarios are introduced into the lower operation benefit optimization model in the form of a penalty function. Secondly

in order to ensure the stable operation of the system under the condition of insufficient number of extreme scenario samples

CWGAN-GP is used to construct the extreme scenario generation method

and the extreme scenarios are generated in large quantities to ensure the economy and stability of the results of the optimal allocation of the capacity as much as possible. The proposed method is verified by using the scenario data of isolated island grid collected from a province of Southern Power Grid

and the results show that the optimized energy storage capacity can effectively ensure stable system operation. The power balance violation rate in various operation scenarios is 0

and the investment return ratio can reach 5.53.
