Regional comprehensive energy multi-stage planning method considering economy and carbon emission reduction

Abstract

The invention discloses a regional integrated energy multi-stage planning method considering economy and carbon emission reduction, comprising the following steps: (1) obtaining a multi-energy tidal current model according to a multi-energy tidal current solving result and an energy balance law, the multi-energy tidal current model being used for a multi-energy tidal current solving result of a regional integrated energy system; (2) selecting the construction time sequence of each energy device and pipeline as a variable, and obtaining the maximum economic benefit and carbon emission reduction benefit through optimization; (3) on the basis of a multi-energy tidal current model and a solving result, minimum economic cost and carbon emission reduction are taken as an optimization objective function, input, output and transmission upper and lower limits of each energy device and each energy pipeline are taken as constraint conditions, and meanwhile, a device model and investment cost are taken as limiting conditions; solving construction schemes and corresponding costs of the energy equipment and the energy pipeline when the comprehensive cost of the target function is minimum; and (4) iteratively solving a regional integrated energy system multi-stage planning scheme considering economy and carbon emission reduction on an MATLAB simulation platform by adopting a dynamic planning algorithm.

Description

technical field [0001] The invention relates to the field of regional comprehensive energy planning, in particular to a multi-stage planning method for regional comprehensive energy considering economy and carbon emission reduction. Background technique [0002] In order to cope with global climate change and energy crisis, low-carbon transformation has become the primary theme of the development of the global power industry. The energy sector has a significant carbon lock-in effect, so systems in this sector require both economic and carbon reduction benefits at the planning level. The multi-energy network is the carrier of energy transmission and management, and plays an important role in rationally allocating energy resources and demands. A reasonable energy network structure can not only reduce energy consumption and indirectly reduce the carbon emissions of industrial users, but also promote the consumption of intermittent renewable energy and reduce the comprehensive ...
