A Day-Ahead Scheduling of Equivalent Energy Storage Model Considering Minimum-On-Off Time

Abstract

In order to make Thermostatically Controlled Loads (TCLs) better meet the scheduling requirements, a day-ahead scheduling of equivalent energy storage model that takes into account of the minimum-on-off time is established. By considering the minimum-on-off time, the charging and discharging power, as well as the energy storage are modified, and the relationship between heat exchange power and energy storage are developed. By this way, the equivalent energy storage model more accurately reflects the real thermodynamic characteristic of TCLs and enables TCLs to exert the actual potential to participate in the scheduling. Finally, the simulation results verify the feasibility of the proposed scheduling method.
