摘要：
In order to reduce the deviation of actual execution and transaction results of power retailers in electricity market, this paper proposes a direct control strategy based on the variable frequency air conditioning (VFAC) load model to track the feeder load planning value. This strategy uses discrete Fourier transform and proportional-integral (PI) control to find out the scheduling demand of VFAC group, and then realizes the scheduling demand by changing the temperature setting of VFAC. Simulation results show that this strategy can achieve feeder load tracking with lower action times and temperature changes, and reduce the assessment power of electricity retailers. The proposed strategy not only improves the power balance of the distribution network, but also improves the income of electricity retailers. © 2019 Automation of Electric Power Systems Press.
