摘　　要：风电光伏作为清洁可再生能源,其并网利用是实现能源结构调整的重要手段。但是,大规模风电光伏并网会影响电网运行的稳定性,主要表现为减弱系统惯性、电压波动增大以及稳定边界缩小等,威胁电网安全稳定运行。因此,保障并网运行稳定性是实现大规模风电光伏并网的关键。深入分析影响并网稳定性的因素,采取切实有效的控制对策,既是确保电网安全的必要之举,也是维护社会经济可持续发展的当务之急。先分析并网对电网的影响,然后提出控制策略来提升系统稳定性,为大规模风电光伏并网的稳定运行提供参考。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.
