Optimal Operation Strategy of PV-Charging-Hydrogenation Composite Energy Station Considering Demand Response

Traditional charging stations have a single function, which usually does not consider the construction of energy storage facilities, and it is difficult to promote consumption new energy. With gradual increase in number vehicles (NEVs), give full play complementary advantages source-load resources provide safe, efficient, economical supply services, this paper proposes optimal operation strategy PV-charging-hydrogenation composite station (CES) that considers demand response (DR). Firstly, mode CES analyzed, model, including photovoltaic power generation system, fuel cell, hydrogen production, storage, hydrogenation, charging, established. The purpose services for electric (EVs) cell (HFCVs) at same time. Secondly, according travel law EVs HFCVs, distribution hydrogenation different periods day simulated by Monte Carlo method. On basis, following two models are established: load based on price elasticity matrix interruptible incentives. Finally, multi-objective model considering DR proposed minimize comprehensive operating cost fluctuation CES, maximum–minimum method analytic hierarchy process (AHP) used transform into linearly weighted single-objective solved via an improved moth–flame optimization algorithm (IMFO). Through simulation examples, results four scenarios obtained. Compared with situation DR, can reduce CNY 1051.5 17.8%, verifies effectiveness model. In addition, impact solar radiation recharge changes operations was also studied, resulting data show were more sensitive changes.
