Comprehensive energy system planning method and device considering multi-type energy storage configuration

Abstract

According to the comprehensive energy system planning method and device considering the multi-type energy storage configuration and the comprehensive energy system considering the multi-type energy storage configuration provided by the invention, the comprehensive energy system is internally provided with the energy storage equipment of various energy sources, and the energy conversion equipment of different energy source forms is additionally arranged; therefore, the flexibility of the whole energy system is improved; when the comprehensive energy system is planned, a single objective function enabling the planning cost to be the lowest is determined according to energy price prediction information of various energy in a preset time period and operation data of each energy conversion device and each energy storage device, and the single objective function is optimized and solved. Reasonable investment is carried out on the equipment scale by using the solved optimal control instruction, and reasonable optimal scheduling is carried out on the internal component equipment, so that the method can better adapt to the operation of the comprehensive energy system, and the benefit maximization is achieved.

Description

technical field [0001] The invention relates to the technical field of energy management, in particular to a comprehensive energy system planning method and device considering multi-type energy storage configurations and an integrated energy system considering multi-type energy storage configurations. Background technique [0002] As a new form of energy system, the integrated energy system integrates various energy sources such as electricity, gas, heat, and cold, which improves the operating efficiency of the energy system, reduces the operating cost of the energy system, and improves the operation efficiency of the energy system. flexibility; with the promotion of integrated energy systems, the coupling between multiple energy sources has been further strengthened. [0003] Since the energy supplier's highest efficiency operating point often does not match the user's maximum benefit point of energy consumption, the installation of energy storage devices in the integrated ...
