考慮換電儲(chǔ)備的電動(dòng)汽車光伏換電站動(dòng)態(tài)功率分配方法
[Abstract]:Power distribution is the key problem in the actual operation of photovoltaic power station of electric vehicle. In this paper, the system structure of photovoltaic power station and the functional model of its basic components are given. In order to evaluate the operation performance of photovoltaic power station, the operation performance evaluation index reflecting the availability of power exchange service and the local absorption and utilization of renewable energy is constructed. On this basis, a dynamic power allocation method of photovoltaic power station considering power exchange reserve is proposed: on the one hand, the short-term demand prediction results are introduced to establish the power exchange service model; on the other hand, according to the total amount of power cells and photovoltaic output power available in each period of time, the power distribution model is established. Through the simulation solution of the actual photovoltaic power station operation example, the rationality and correctness of the model are verified from the aspects of system power balance, operation performance index analysis and so on. The simulation results show that the method can effectively improve the local absorption ratio of photovoltaic under the premise of ensuring the availability of power exchange services. The method proposed in this paper will provide theoretical basis and technical support for the optimal operation of demonstration urban power stations in China.
