摘要：

Considering the loss cost of power batteries, a multi-time scale optimal dispatching strategy of electric buses participating in vehicle-to-grid (V2G) is proposed. Firstly, based on the principle of engineering economics, a loss model of power battery is established. In order to optimize both the battery loss cost and the charging-discharging plan of charging station, an iterative method is adopted to minimize the daily operation cost of the bus company in upper layer of day-ahead stage. Based on results optimized in the upper layer, the charging-discharging plan of charging station is further optimized to minimize the peak-to-valley difference of distribution network. In the intraday stage, the output power of photovoltaic (PV) and the base load power of distribution network are wavily updated, the day-ahead plan is revised in order to minimize the daily operation cost of bus company and the deviation between day-ahead plan and intraday plan. Finally, from the perspectives of bus company and power grid, three strategies of unordered charging, orderly charging and participating in V2G are compared and analyzed to verify the superiority of electric bus participating in V2G. The changing trend of the operation cost of bus company with different V2G compensation coefficients is reflected by sensitivity analysis. © 2020 Automation of Electric Power Systems Press.
