Switch Control Used to Coordinate Different Demand Response Resources

Abstract

with a variety of new energy access to the power grid, its frequency control is facing many new challenges, and the demand response resources play an increasingly important role in FM (frequency modulation). In this paper, the intermittent characteristics of demand response resource is described, which is determined by the user's comfort and the physical characteristics of the demand response resources themselves. For example, air conditionings are disconnected for a period of time to maintain constant room temperature. Electric vehicle need to charge themselves after participating in the frequency response. The intermittent characteristics will reduce the performance of frequency control without coordination. Thus the coordination strategy will be designed for diffident demand response resources based on switch control method. And the simulation results show the effectiveness of the coordination strategy.
