At present, the optimal landscape storage capacity allocation scheme is obtained by taking the lowest Levelized Cost of Energy (LCOE) as the optimization objective in the landscape storage model . However, it only operates under the island model and does not consider the influence of energy storage capacity configuration on system stability.
Zeqing Zhang; Capacity configuration optimization of energy storage for microgrids considering source–load prediction uncertainty and demand response. 1 November 2023; 15 (6): 064102. The fluctuation of renewable energy resources and the uncertainty of demand-side loads affect the accuracy of the configuration of energy storage (ES) in microgrids.
Provide an optimal allocation and capacity of non-dispatchable renewable DER and grid-scale energy storage units in a spatially dispersed hybrid power system under an imperfect grid connection by combining the dynamic optimal power flow and PSO optimization.
