Operation Optimization Strategy of Park-Level Integrated Energy System Considering Thermal Inertia

There is a huge difference in the response time constant between power and heat in the integrated energy system of the park, which can be used to establish a regional heat network model considering the thermal inertia of the heat network, according to which the power of the energy system can be adjusted to a certain extent to optimize the operation of the park. In this study, a mathematical model is established for the heat exchange between the heat network and the building and the surrounding environment, and the operation optimization strategy of the park is established with the goal of the optimal operation economy for the thermal users, and the feasibility of the proposed strategy is verified by an example.
