Cooperation of Demand Response and Traditional Power Generations for Providing Spinning Reserve

Abstract

Spinning reserve in the electric power system is vital in dealing with the sudden drop of electricity supply caused by failure, which used to be provided by traditional power generations. With the development of information and communication technologies (ICTs), demand response (DR) is deployed gradually for providing spinning reserve by shedding flexible loads. Air conditioners (ACs) are one of the most high-quality flexible loads due to its high proportion of capacity in electricity consumption. However, power rebound spike (PRS) of AC loads tend to emerge at the end of DR. Therefore, traditional spinning reserve providers (TSRPs) have to ramp to cooperate with ACs immediately. In this paper, a DR management approach is proposed for controlling DR duration time and capacity by sequent temperature configuration. Meanwhile, the connection between PRS and DR duration time is studied. Reliability indices have also been applied to evaluate different cooperation strategies between ACs and TSRPs. Simulations based on Monte Carlo methods are performed quantitatively.
