Multi-objective Fuzzy Optimal Scheduling for Multi-energy Flow System Considering Off Design Characteristics

A multi-objective fuzzy cooperative optimization model of multi-energy flow system under off design characteristics is established in this paper. Firstly, based on the consideration of new energy, electric energy storage, and thermal energy storage, a high-order nonlinear model of the equipment under off design characteristics is established. Then, according to the requirements of different engineering application modes, the multi-energy flow system collaborative optimization model with economic, environmental protection and energy saving as the optimization objectives is proposed, and the multi-objective fuzzy collaborative optimization model is established based on the fuzzy theory. Finally, the model is applied and verified by a multi-energy flow system example. The proposed multi-objective fuzzy optimal scheduling of multi-energy flow system under off design characteristics is the basis of cooperative operation, operation design and engineering calculation analysis of multi-energy flow system.
