Abstract

The invention discloses a park comprehensive energy system equipment model selection and capacity planning method considering electric energy storage. The method is based on solving the problems of equipment type selection and corresponding capacity planning in a park comprehensive energy system containing energy storage. The minimum annual comprehensive cost is taken as an objective function, operation constraints and power balance constraints of electric energy storage equipment and various energy conversion equipment of a comprehensive energy system in a park are fully considered, a mixed integer linear programming method is adopted for solving, and finally an equipment type selection and capacity planning scheme is obtained. According to the method, the effects of improving energy space-time distribution and improving operation economy of the electric energy storage system are fully considered, and a mixed integer linear programming solver is adopted for optimization calculation, so that equipment model selection and capacity planning are more scientific and accurate.

Description

technical field [0001] The invention relates to a method for equipment type selection and capacity planning of a comprehensive energy system in a park. In particular, it involves a method for equipment selection and capacity planning of the park's comprehensive energy system considering electric energy storage. Background technique [0002] In the traditional energy utilization model, the energy system can be divided into power system, thermal system and natural gas system according to the type of energy. Due to the difference in physical characteristics, each energy system has different characteristics in system planning and design. However, the traditional energy supply and utilization method that separates electric energy, thermal energy, and natural gas dispatch and supply does not consider the connection between the electric power system, natural gas system, and thermal system, and cannot fully explore their respective energy supply advantages and potentials. In recent...
