Coordinated dispatch strategy of air conditioners for providing load regulation service

Abstract

As the penetration of renewables increases, air conditioners (ACs), whose electricity consumptions account for a large share, present tremendous potential in providing load regulating service to maintain the power supply–demand balance. In this paper, an analytical model for the dynamic aggregated power and schedulable capacity of ACs is presented, where the safe protocol (SP) is utilized to eliminate the power oscillations caused by temperature setpoint shifting. Based on this, the response potential of ACs is quantified by the evaluation indexes in the dimensions of capacity and time. Besides, an optimal dispatch strategy is proposed to implement the coordination of air conditioning resources in the response stage and recovery stage, by which not only the reliable load regulation service can be provided, but also the influences on users can be minimized. Simulation studies demonstrate the effectiveness of the proposed method.
