Probability evaluation of combined output of wind power and photovoltaic power generation considering the influence of multi-parameter faults

Joint power generation,operating status,probability assessment,Monte Carlo method

The incorporation of a large number of wind and photovoltaic power plants into the grid will bring severe challenges to the reliability of the power system. In order to better evaluate the grid connection of wind farms and photovoltaic farms, this paper establishes a reliability model of the combined output of wind farms and photovoltaic farms by taking into account the randomness and volatility of the wind and wind, as well as the failure, downsizing and outage of the power genera-tion equipment inside wind farms and photovoltaic farms. Based on monte carlo method, the fault running state and under the normal operation of the wind power generation systems, photovoltaic power generation system and output probability assessment scenery combined power generation system, the simulation results show that considering the beautiful scenery of the combined power system fault state output is more in line with the actual joint operation of the power system, has certain reference value for grid scheduling.
