Optimal configuration method for user-side comprehensive energy system

Abstract

The invention discloses a user side comprehensive energy system optimal configuration method, and belongs to the field of comprehensive energy system optimal configuration. The method comprises the following steps: S1, building an all-working-condition energy conversion model of equipment according to the energy structure of the southwest region and the characteristics that the efficiency of operation equipment changes along with the environment and output, the full-working-condition energy conversion model comprises a natural gas internal combustion engine, a gas turbine, a hot water type gasboiler, a hot water type waste heat boiler, an absorption refrigerator, a photovoltaic and wind power generation system, a water source heat pump and an energy storage device. Aiming at the current energy situation of a specific region in the southwest region, according to an all-working-condition energy consumption scene with a changed conversion efficiency coefficient, an all-working-conditionmathematical model of each part of equipment is established, optimal configuration of the user-side comprehensive energy system is carried out, the precision of the optimal configuration model is high, and the improvement of the accuracy and rationality of system planning is facilitated.

Description

technical field [0001] The invention relates to the field of optimal configuration of comprehensive energy systems, in particular to a method for optimal configuration of user-side comprehensive energy systems. Background technique [0002] Integrated energy system refers to the integration of multiple energy sources in a certain area to realize coordinated planning, optimized operation, collaborative management, interactive response and mutual assistance among multiple heterogeneous energy subsystems. While meeting the diversified energy demand within the system, it is necessary to effectively improve energy utilization efficiency and promote a new integrated energy system for sustainable energy development. [0003] The integrated energy system is one of the important forms of the development and application of the Energy Internet. As a multi-input and multi-output system, it includes a variety of energy input, conversion and storage equipment. The integrated energy syste...
