基于动态减载的风蓄联合优化运行与调频控制策略
Optimal Operation and Frequency Regulation Control Strategy for Wind and Pumped Storage Unit Combined System Based on Dynamic Deloading
摘要
Abstract
Under the dual carbon target,the penetration rate of renewable energy sources is increasing year by year.However,the random fluctuation of their output poses great challenges to the frequency security and stability of the power system.En-abling active participation of the renewable energy sources unit in frequency regulation and their joint participation with en-ergy storage is an important way for the evolution of the novel power system from the perspective of dispatching.To address this issue,a wind turbine dynamic deloading control strategy was proposed based on the wind power reserve control meth-od which quantifies the frequency control capacity supply un-der different wind conditions.By combining the frequency reg-ulation characteristics of the pumped storage unit under various operating conditions,characterizing the uncertainty of wind power and load fluctuations in the form of chance constraints and setting system frequency regulation reserve constraints,a wind-storage joint optimization operation model based on dy-namic deloading was established,and various wind-storage joint frequency control strategies were proposed.Numerical ex-amples demonstrate that the proposed method can promote the consumption of wind power and optimizes the economic viabil-ity of wind storage combined systems while ensuring system frequency safety as well.关键词
