The optimal dispatch of MES is a mixed integer nonlinear programming problem, which is to obtain the optimal dispatch strategy of MES with the minimum load curtailment under the coupling constraints of the distribution system and transportation network. The optimal dispatch strategy includes the path planning scheme and the power dispatch scheme.
An internal dispatch method for HPSs contributes to their optimal management. The variable time resolution approach achieves optimal solutions in reasonable time. Exploitation of imbalance tolerances may increase revenues for the station. BESS of high rated power and limited energy capacity improve operation of the HPS.
Main objective of the internal dispatch policy is to maximize the operating profit of the HPS-O by optimally exploiting available RES energy, while avoiding deviations from the DOs issued by the SO, via proper coordination of the generation and storage facilities of the HPS.
