Probe into Grid Voltage's Reactive Power Optimal Control Scheme Based on Load Identification

This paper puts forward a scheme for grid voltage’s reactive power optimal control based on load identification,and points out that the scheme can accurately identify the running situation of grid load,and connecting with the counter-adjusting requirement to voltage,provides the principle of constant setpoint regulation in each load range,corrects and controls the fixed value in real time,makes the real-time interaction between voltage’s reactive power control and the load variation,increasing the control efficiency of voltage’s reactive power control,and realizing the optimal control.
