Capacity Allocation Optimization Method for Integrated Energy Systems Based on Multi-energy Flow Balancing

In order to solve the problem of strong nonlinearity of the equipment model, this paper proposes a configuration optimization method based on energy flow balance. First, establish a non-linear fitting model of the equipment according to the system structure requirements, and then filter out the feasible capacity configuration range according to the constraint conditions, and use the finite enumeration method to perform uniform traversal. Under each configuration scheme, the equal micro-increment method is adopted, and the scheduling optimization calculation is performed based on the energy flow balance. Finally, the optimized configuration results are established. Taking an office building in a park as an example, the configuration calculation is performed using the method proposed in this paper and commercial solver. The results show that this method can better ensure the accuracy of the model.
