摘要:

本文针对惯量飞轮和高速飞轮组成的混合飞轮阵列参与电网惯性响应与一次调频的复杂控制问题,首先介绍了惯量飞轮和高速飞轮储能的概念、惯量飞轮阵列与高速飞轮阵列参与电网惯性响应和一次调频的架构及其工作机理,其次建立了飞轮储能系统数学模型及其控制模型,然后提出了惯量飞轮和高速飞轮阵列参与电网惯性响应和一次调频的基于惯性控制和下垂控制的协同控制策略、惯性响应与一次调频分别调节控制策略。通过仿真将两种控制策略的调频效果从电网频率变化量、频率变化率和恢复时间等方面进行对比,仿真结果验证了两种策略的正确性和可行性,它们在惯性响应和一次调频阶段各有优势。

Abstract:

Aiming at the complex control problem wherein a hybrid flywheel array composed of an inertia flywheel and a high-speed flywheel participates in grid inertia response and primary frequency modulation, this paper first introduces the concepts of magnetic suspension inertia flywheel and high-speed flywheel energy storage, as well as the architecture and working mechanism of the inertia flywheel array and high-speed flywheel array that participate in grid inertia response and primary frequency modulation. Secondly, the mathematical and control models of the flywheel energy storage system are established, and two control strategies are proposed: one is a collaborative control strategy based on inertia control and sag control, involving the inertia flywheel and high-speed flywheel array in grid inertia response and primary frequency modulation; the other is a control strategy based on inertia response and primary frequency modulation, respectively. Through simulation, the frequency modulation effects of the two control strategies are compared in terms of frequency change, frequency change rate and recovery time. The simulation results verify the correctness and feasibility of the two strategies, and they exhibit different advantages in the inertia response and primary frequency modulation stages.

Key words: flywheel energy storage, inertia flywheel, inertial response, primary frequency modulation, sag control, inertial control
