摘要

面对大规模波动性新能源并网带来的电网频率安全问题，飞轮储能辅助火电机组参与调频可以有效提升电网发电侧频率主动支撑能力，是能源结构转型期间支撑电网频率安全的有效保障。针对飞轮储能系统的出力控制策略和容量优化配置，提出一种用于辅助火电机组一次调频的飞轮储能控制策略与容量配置一体化方法。首先设计了一种考虑机组实时状态的飞轮储能协同调频控制策略；提出了考虑电厂一次调频收益的经济评估模型，采用改进的粒子群算法进行求解；最后采用华北某电厂315 MW机组实际调频数据进行仿真验证。仿真结果表明，所提出一体化配置方案能够在有效改善电网调频效果的同时兼顾投资方收益，该研究对推动飞轮储能辅助火电参与电力系统调频服务的现场工程应用具有重要理论指导意义。

Abstract

Facing the frequency security problem caused by large-scale integrations of fluctuating new energy

the participation of thermal power units coupled with flywheel energy storage in frequency regulation can effectively improve the active power support capability of the power grid from the generation side

which is an effective guarantee for the frequency security of the power grid. According to the output control strategy and capacity configuration of flywheel energy storage systems

this paper proposed a combined method of flywheel control strategy and capacity configuration for primary frequency regulation to optimize the thermal power unit operations.Firstly

a coordinated frequency regulation control strategy of flywheel energy storage considering the real-time power output of thermal power units is designed. An economic evaluation model considering the primary frequency regulation benefit of power plants is proposed

and a refined particle swarm optimization algorithm is utilized to tackle the problem. Finally

the actual data of a 315 MW unit in a power plant from the northern part of China are simulated and verified. The result shows that the proposed integrated configuration strategy can effectively improve the frequency modulation effect of the power grid while taking the cost of energy storage investments into account.The research results are of great significance for promoting engineering applications of flywheel energy storage participating in frequency regulation services.
