Abstract:Cooperative dispatching of electric vehicle （ EV ） and renewable energy is one of the effective means to promote the absorption of renewable energy， to calm the fluctuation caused by grid-connected renewable energy and to reduce the impact of EV disordered charging on the power grid. In order to reduce the net load fluctuation of photovoltaic （ PV ） power grid， a mathematical model of cooperative dispatching between EV and PV generation was established. At the same time， because of the lack of quantitative analysis on the load characteristics of electric vehicles after orderly charging， the characteristic evaluation index was proposed to quantitatively analyze the load characteristics of electric vehicles after response dispatching， and to evaluate the effect and influence of coordination dispatching. Finally， the data of one area of Tianjin were used for simulation analysis. The results showed that the proposed cooperative scheduling model could effectively suppress renewable energy fluctuation and decrease load peak-valley difference under different PV permeability.
