摘要

双碳目标背景下，新能源渗透率逐年升高，其出力随机波动性给电力系统频率安全稳定带来严峻挑战。从调度层面考虑新能源机组主动参与调频、与储能联合参与调频是新型电力系统演进的重要途径。对此，基于风电功率备用控制方法，提出了全风况下风电动态减载控制策略，量化了不同风况的调频容量供应能力。结合抽水蓄能机组不同工况下的调频特性，以机会约束形式表征了风电出力与负荷波动的不确定性并设置系统调频备用约束，建立基于动态减载的风蓄联合优化运行模型，提出了不同工况下风蓄联合调频控制策略，通过算例验证了所提策略能够在保证系统频率安全的前提下，促进风电消纳，提高风蓄联合系统的经济性。

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. Enabling active participation of the renewable energy sources unit in frequency regulation and their joint participation with energy 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 method which quantifies the frequency control capacity supply under different wind conditions. By combining the frequency regulation 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 dynamic deloading was established

and various wind-storage joint frequency control strategies were proposed. Numerical examples demonstrate that the proposed method can promote the consumption of wind power and optimizes the economic viability of wind storage combined systems while ensuring system frequency safety as well.
