摘要

随着新型电力系统有功-频率耦合特性逐渐复杂化，传统单一储能并网调频策略给电力系统一次调频带来巨大压力，多类型储能组合参与一次调频模式及储能协同控制下的电网频率特性亟需研究。该文分别研究基于下垂控制的电化学储能与基于虚拟同步机控制的飞轮储能的频率响应机理，在多类型储能参与电力系统一次调频时利用低通滤波环节对频率变化率信号进行处理，达到储能协调控制效果；接着，将多类型储能协调控制模型与包含新能源与传统火电的电力系统相结合，建立电力系统频率响应(system frequency response, SFR)模型，利用该模型量化分析储能相关参数对系统频率变化率和稳态频率偏差的影响，并进行参数灵敏度分析；最后，在Matlab/Simulink上搭建模型，验证多类型储能相关调频参数对系统频率特性的影响。研究证明，新型电力系统调频单元考虑多类型储能协调控制能够提升电力系统频率稳定性。

Abstract

With the gradual complexity of the active power-frequency coupling characteristics of the new power system, the traditional single energy storage grid-connected frequency regulation strategy has brought huge pressure to the primary frequency regulation of the power system. The participation mode of multi-type energy storage in primary frequency regulation and the frequency characteristics of the power grid under the coordinated control of energy storage need to be studied urgently. This paper studies the frequency response mechanism of electrochemical energy storage based on droop control and flywheel energy storage based on virtual synchronous machine control respectively. When multi-type energy storage participates in the primary frequency regulation of the power system, the low-pass filter link is used to process the frequency change rate signal to achieve the coordinated control effect of energy storage. Then, the coordinated control model of multi-type energy storage is combined with the power system containing new energy and traditional thermal power, and the frequency response model of the power system is established. The model is used to quantitatively analyze the influence of energy storage-related parameters on the system frequency change rate and steady-state frequency deviation, and the parameter sensitivity analysis is carried out. Finally, the model is built on Matlab/ Simulink to verify the influence of multi-type energy storage-related frequency regulation parameters on the system frequency characteristics. The research proves that considering the coordinated control of multi-type energy storage in the frequency regulation unit of the new power system can improve the frequency stability characteristics of the power system.
