摘要: |
建立含有风电、光伏发电和可入网电动汽车(PEV)的电力系统概率潮流模型。基于历史气象数据对不同季节和不同天气状况下的风光数据进行模拟,并计及风电、光伏发电、PEV充/放电及负荷的不确定性,在此基础上,对不同季节中每日不同时段的电力系统采用三点估计法(3PEM)进行概率潮流计算,进而计算潮流结果的统计特性。某140节点配电系统的仿真结果验证了所提模型和方法的准确性。 |

Abstract: |
A probabilistic load flow model is developed for the power system containing WFs(Wind Farms),PVs(PhotoVoltaic Generations) and PEVs(Plug-in Electric Vehicles). The wind speeds and solar radiations are simulated based on the historical meteorological data for different season and weather conditions and the uncertainties of WF,PV,PEV and load are considered,based on which,3PEM(3-Point Estimation Method) is adopted to calculate the probabilistic load flow of power system for different daily periods and different seasons. Its statistical characteristics are thus obtained. The simulative results of a 140-bus distribution system show the correctness of the proposed model and method. |
