Analysis of Emergency Demand Response Levels of Central Air-Conditioning

Central air-conditioning (CAC) is a flexible load which can be dispatched during an emergency demand response (EDR) program. However, consumers’ trade-off between thermal comfort levels (TCLs) and profits will affect the potential of CAC. Therefore, this paper proposes a method to evaluate CAC’S response levels. An EDR optimization model simulating consumers’ trade-off between TCLs and profits is established and it is solved by a particle swarm optimization (PSO) algorithm. Then the definition of EDR levels is presented to quantitatively analyze the capability of CAC providing the EDR. Furthermore, uncertainty of EDR levels caused by stochastic initial indoor temperature is analyzed through a Monte Carlo (MC) simulation. A case study shows the rationality of the presented method, and the effects of weight coefficients, compensation prices and penalty prices on EDR levels are also analyzed.
