Research on Optimal Scheduling of RIES Based on Incentive Integrated Demand Response

Integrated demand response (IDR) and energy storage equipment are important in the context of global energy internet. The two factors can optimize the accommodation capacity of renewable energy, improve the level of peak load shifting, and make the operation of power system more economical. The regional integrated energy system (RIES) has developed strong research value after the concept of integrated energy system has been put forward. Firstly, the RIES model, including the dimension of renewable energy, energy conversion equipment, energy storage equipment and multi energy load, is established. Secondly, the load can be categorized into fixed load, reducible load, transferable load and replaceable load. Taking the lowest total operating cost of RIES as the objective function, an incentive integrated demand response scheduling strategy is proposed. Taking an industrial park in China as an example, the model is solved by using CPLEX with YALMIP. The result indicates that the scheduling strategy proposed in this paper can not only realize the peak load shifting, but also gain better economic benefits.
