Abstract

The invention relates to a park-level integrated energy system capacity optimization configuration method and system. The method comprises the steps of obtaining park cold, heat and electricity load power corresponding to each optimization time period; and substituting the cold, heat and electricity load power of the park corresponding to each optimization time period into a pre-established comprehensive energy system capacity optimization configuration model for solving to obtain the optimal configuration capacity of various devices in the comprehensive energy system. According to the technical scheme provided by the invention, the influence of the pollutant emission amount and the primary energy consumption amount of the system on optimization is considered, and the planning reasonability is improved.

Description

technical field [0001] The invention relates to the field of comprehensive energy system planning, and in particular to a method and system for optimally configuring the capacity of a park-level comprehensive energy system. Background technique [0002] With the increasingly severe energy and environmental problems, how to improve energy utilization and minimize environmental pollution caused by energy use has become an important topic in the field of energy at home and abroad. [0003] The core of the Energy Internet is still the power system, but it connects the power system with the gas network, cold / hot water pipe network and transportation network, and couples it into a multi-network fusion system. The integrated energy system is an important bearing form in the Energy Internet. It plays the role of multi-energy coupling and coordination, and is an important carrier to improve the overall energy supply efficiency of the system and promote the consumption of new energy. ...
