In this paper, a optimal configuration method of energy storage in grid-connected microgrid is proposed. Firstly, the two-layer decision model to allocate the capacity of storage is established. The decision variables in outer programming model are the capacity and power of the storage system.
Therefore, the expression of constraints on reliability performance of microgrid system is shown as, (14) Q C = Q FC + Q RC Q RC ≥ Q RCmin where Q FC represents flexible energy storage capacity, Q RC stands for rigid energy storage capacity, Q RCmin represents the minimum rigid energy storage capacity during off-grid operation.
For example, artificial bee colony algorithm, grey wolf optimization algorithm, bat search algorithm, genetic algorithm have been widely used in optimizing the capacity configuration of microgrids. However, most of these studies have not simultaneously considered collaborative optimization of planning and operation.
