摘要
随着能源转型的不断推进,风电与光伏发电站的数量不断增多,大规模的风电与光伏并入大电网,必然会影响大电网的稳定性。为解决上述问题,光伏发电站、风电场等新能源发电站往往选择配置储能系统,以提高电站出力的稳定性。对含储能的新能源发电站,其能量管理系统需满足电站一二次调频需求,并能够有效完成惯量支撑及振荡抑制功能。本文提出一种通用控制方法,通过对控制需求进行分频,高频部分优先使用储能等进行快速调节,低频部分优先采用风光设备进行稳定平缓调节,以充分利用设备的调节性能、满足不同调节需求,旨在对不同调节需求下均能达到较好的调节效果,并提高发电设备、储能设备运行寿命,降低因调节产生的综合成本。
With the continuous advancement of energy transformation,the number of wind and photovoltaic power stations is constantly increasing.The large-scale integration of wind and photovoltaic power into the large power grid will inevitably affect the stability of the large power grid.To solve the above problems,new energy power stations such as photovoltaic power plants and wind farms often choose to configure energy storage systems to improve the stability of power station output.For new energy power stations with energy storage,the energy management system shall meet the primary and secondary frequency regulation requirements of the power station,and be able to effectively complete the inertia support and oscillation suppression functions.This article proposes a universal control method,which divides the control requirements into frequency,prioritizes the use of energy storage for quick adjustment in the high-frequency part,and stabilizes and gently adjusts the low-frequency part using wind and solar equipment to fully utilize the equipment's regulation performance and meet different regulation needs.The aim is to achieve good regulation effects under different regulation needs and improve the operating life of power generation and energy storage equipment,reduce the comprehensive costs incurred due to regulation.
