In the context of energy conservation and emission reduction, self-supplied power plant units and energy-using equipment of ithe ndustrial enterprise power grid show a trend of increasing single-unit capacity. While improving the energy efficiency of enterprises, it also brings new challenges to the safe and stable operation of the enterprise power grid. This paper looks at the power balance control problem faced by industrial enterprise power grid, and proposes an adjustment method for industrial load to participate in active power balance and introduces a fast closing valve as a means of stability control. Finally, an overall scheme and implementation path of an active coordination control system are proposed. The rapid response of power and load enables fine control of the industrial enterprise power grid normal production and accident emergency, and provides technical support for improving the safe and stable operation level of the enterprise power grid and enterprise economic benefits. Engineering practice in an electrolytic aluminum enterprise power grid shows that this method is feasible.
