Optimal Planning of District Integrated Energy System considering Distributed Renewable Energy

In this paper, on the premise of meeting the needs of users in the park for electricity, cooling and heating, and following the goal of minimizing costs, we plan for the equipment and energy in the system. Based on the example data of a certain park in the north, the gurobi solver is called to solve the model on the MATLAB simulation platform combined with the yalmip toolbox. This paper compares and analyzes the planning schemes with or without solar energy output and with or without energy storage output. The simulation results prove the validity of the built model. The planning results prove that adding energy storage equipment and solar energy output equipment to the system can improve economy and energy supply. Reliability has certain advantages. In addition, this paper considers the impact of uncertain fluctuations in load and solar energy output on the planning of the integrated energy system, and the results show that the capacity allocation of energy storage equipment and solar energy output equipment is greatly affected by fluctuations.
