Demand Pattern of Decentralized Fixed Speed Compressor Air-Conditioning Systems and Demand Response Potential

Abstract

this research focus on obtaining the demand pattern of fixed speed compressor air conditioning systems (FSCAC) and analyze their demand response potential. First an experiment is done to get the demand pattern of a FSCAC and then a model is developed to simulate the power consumption using available thermal model of a house in MATLAB/Simulink. Using this model, an aggregated model of a building is created to simulate the real world power consumption. Building model is used to show the demand reduction capability by increasing thermostat temperature set points. 50%-60% reduction of running average demand of the building is obtained by 4 °C increase of thermostat set point. The thermal model of a house is then altered to get the energy consumption of a FSCAC. It is shown that 50% energy reduction in 24 hours of operation is possible by 4 °C increase of thermostat set point.
