Day-Ahead Dispatch Model Considering Multi-Type Loads

Abstract

In the smart grid, the adjustable loads have played an important role in peak shaving. According to demand side management in China, models of the shiftable, transferable and interruptible loads are constructed respectively in this paper. Considering the feasibility of the practical dispatch, the graded scheduling strategy is put forward. Aiming at peak shaving, the adjustable loads are utilized to participate in the optimal economic dispatch with the conventional units. Then a lean day-ahead scheduling model based on multi types of interactive loads is established. This model guides these loads with incentives to realize the optimal configuration of demand side resource. Simulation results indicate that under the circumstance of the limited regulation capacity of conventional units, the more actively the clients join in the interaction, the lower the total cost is and the better the interactive effectiveness is.
