Analysis and Control Strategies for the Stability of Wind and Photovoltaic Grid-Connected Operation
Wind and photovoltaic power,as clean and renewable energy sources,play a crucial role in the adjustment of energy structure through grid integration.However,the large-scale integration of wind and photovoltaic power can impact the stability of the electrical grid,primarily manifesting as reduced system inertia,increased voltage fluctuations,and a shrinking stability boundary,which may threaten the safe and stable operation of the grid.Therefore,ensuring the stability of grid-connected operation is key to achieving large-scale integration of wind and photovoltaic power.Conducting an in-depth analysis of the factors affecting grid stability and adopting effective control strategies is not only imperative for ensuring grid security but also urgent for maintaining sustainable socio-economic development.The article first analyzes the impact of grid connection on the power grid,and then proposes control strategies to improve system stability,providing reference for the stable operation of large-scale wind and photovoltaic grid connection.
