Optimal operation of integrated energy system including large-scale controllable industrial loads

In view of the large-scale electricity demand of magnesite electrolytic and the problem of co-generation under the restriction of power based on heat, given full play to the operational advantages of multi-source interconnection and overall scheduling in the integrated energy system, an integrated energy system that includes large-scale industrial electric loads and multiple types of residential loads and an optimal operation model for this system are established. Firstly, the operation model of each equipment unit is constructed and coupled to form the overall system architecture; afterwards, the economic cost of system operation is comprehensively considered, and the system economic operation optimization model is established. Finally, simulation verification and analysis of the proposed model and method have been carried out with examples. (c) 2022 Published by Elsevier Ltd.
