Abstract

In recent years, new energy power generation has developed rapidly, and how to absorb the fluctuation of power grid frequency caused by the fluctuation of new energy is the main direction of future development. Using the damping effect of load to simulate the response of load to frequency deviation plays an important role in system frequency response. Usually, the damping coefficient of load is considered as a constant, which can not be adjusted, and is usually measured by practice. This paper studies the effect of electrolytic aluminum with large industrial load on frequency response of power grid. Electrolytic aluminum load is a voltage-driven DC load, which has no frequency response, but has large load capacity and great adjustable potential. Based on this, this paper studies a load damping control method, which responds to the system frequency change by controlling the saturable reactor. The simulation results verify the effectiveness of the proposed control method.

基于主动可调容量协调的电解铝负荷参与电网调频方法

近年来，新能源发电发展迅速，如何吸收新能源波动带来的电网频率波动是未来发展的主要方向。利用负载的阻尼效应来模拟负载对频率偏差的响应在系统频率响应中起着重要的作用。通常，荷载阻尼系数被认为是一个常数，不能调整，通常由实践测量。本文研究了工业负荷较大的电解铝对电网频率响应的影响。电解铝负载是电压驱动的直流负载，无频率响应，但负载容量大，可调电位大。在此基础上，本文研究了一种通过控制饱和电抗器来响应系统频率变化的负载阻尼控制方法。仿真结果验证了所提控制方法的有效性。
