Abstract

Using demand as frequency controlled reserve (DFR) is beneficial to power systems in many aspects. To study the impacts of this technology on power system operation, control logics and simulation models of relevant loads should be carefully developed. Two advanced control logics for using demand as reserve have been presented in this paper. Electricity loads that are applicable for the technique in practical power systems are analysed. Moreover, a simulation model of thermostatically controlled loads, which can provide frequency activated reserve by controlling their set points according to system frequency, is developed. The developed simulation model is able to represent a variety of aggregated thermostatically controlled loads, such as heaters or refrigerators. Uncertainties including customer behaviours and ambient temperature variation are also modelled. Preliminary simulation results are presented and analysed, which demonstrates the great potentials of the DFR technology.
