Stability Analysis and Optimization Analysis of Photovol-taic Grid-Connected Systems
With the continuous expansion of the world's industrial scale,energy consumption is also in-creasing.The extensive exploitation of traditional non renewable fossil fuels has led to an increasingly serious energy crisis.Solar energy,as the most widely used green and pollution-free renewable ener-gy source on Earth,is receiving more and more research and rapid development.Photovoltaic grid-connection is being vigorously promoted,and it is believed that it will be greatly popularized in the near future.However,there are some issues in the photovoltaic system that urgently need to be solved,otherwise it will cause great interference to the power grid.Due to the application of a large number of converters,switches and other components in photovoltaic power generation systems,significant har-monic interference is brought to the operation of grid-connected systems.However,traditional grid-connected control strategies have limited effective damping areas and are difficult to eliminate this interference.To solve this problem,a new control strategy model is established to improve the grid-connected control effect and enhance the stability of photovoltaic grid-connected systems.
