Abstract:In recent years，plug-in electric vehicle （PEV） has developed rapidly.Taking discrepant of the grid connected large number of PEV and clean energy into account，considering the interests of transmission grid，distribution grid and users，a bi-level programming model was proposed.The upper layer optimization in transmission grid aimed at minimizing system operation cost，vehicle owner consumption，wind and light curtailment penalty and total carbon emission，with collaborative scheduling thermal generators，new energy and PEV output，and PEV temporal dimension scheduling was realized；The lower layer optimization in distribution grid level aimed at minimizing the network loss and the PEV spatial dimension scheduling through the optimal power flow calculation was realized.Results of calculating example showed that the effective scheduling of PEV and reasonable power grid planning could reduce the operation cost of power grid and improve its ability to accommodate renewable energy.

Key words:PEV;bi-level optimization;distribution grid;grid programming
