摘要

随着风电大规模并网，其波动性和不确定性严重影响电网频率的稳定，充分利用调频资源对于提升电网的支撑能力至关重要。因此，提出一种可变增益滑模线性自抗扰控制器(VGSM-LADRC)的储能-火电协同调频控制策略。在协同储能和火电出力方面，以机组出力变化范围和旋转备用容量为约束，根据电网频率偏差实现了二者出力的自适应调整；在火电机组出力控制方面，提出VGSM-LADRC根据电网频率偏差来控制其出力深度。负荷扰动仿真结果表明，所提策略相比于储能辅助调频策略对调频资源利用更充分，且VGSM-LADRC实现了更优的火电机组出力控制，使得电网频率偏差有效减小。

Abstract

With the large-scale integration of wind power into the power grid

its volatility and uncertainty have serious impacts on the frequency stability of the power grid. It is crucial to fully utilize the frequency regulation resources to enhance the support capability of the power grid. Therefore

a coordinated frequency regulation control strategy based on the variable gain slide model and linear active disturbance rejection controller (VGSM-LADRC) for energy storage and thermal power is proposed. In terms of the coordination of energy storage and thermal power output

considering the constraints of unit output range and spinning reserve capacity

the adaptive adjustment of their outputs is achieved based on the frequency deviation of the power grid. Regarding the control of thermal power unit output

VGSM-LADRC is proposed to control the output depth based on the frequency deviation of the power grid. Simulation results under load disturbances demonstrate that the proposed strategy allows more efficient utilization of the frequency regulation resources compared with energy storage-assisted frequency regulation strategies. Moreover

VGSM-LADRC achieves superior control of the thermal power unit output

effectively reducing the frequency deviation of power grid.
