Research on grid control of wind-solar energy storage hybrid power generation system
摘要
Abstract
The output power of the wind-solar energy storage hybrid power generation system shows wide fluctuations due to changes in irradiance and wind speed during grid-connected operation when using traditional control methods,affecting the power balance when connecting the power generation system with the electrical grid.To address the issue,a novel improved Perturb and Observe(P&O)method by fuzzy control algorithms is proposed to achieve tracking control of the maximum power point(MPPT)of the photovoltaic array under irradiance variations.Then,an optimal tip-speed ratio control strategy is employed to achieve maximum power point tracking control of the wind turbine under wind speed fluctuations.Charging and discharging of the batteries are controlled in real time based on the balance between power generation and grid power demand.In this way,grid voltage stability and power balance are maintained.Finally,to analyze the output power of each system,a combined wind-solar energy storage generation system model is built.Our results show the proposed method enables the power generation system to stably transmit electric power in a volatile wind-solar environment.关键词
