摘要/Abstract

摘要：

综合能源系统因具有横向“电热冷气水”能源多品种供应及纵向“源网荷储用”多环节协同,是现阶段一种优秀的电力供能系统。根据国家核证自愿减排量方法学与《企业温室气体排放核算方法与报告指南发电设施》研究了基于燃气分布式的综合能源系统碳减排量计算方法,定义了属于该类型项目的基准参照系统。同时结合北京地区某基于燃气分布式的综合能源项目,进行系统碳减排分析。经过研究,该项目在现有电力系统下具有良好的节能减排效应,2016—2020年在运行工况下每年碳减排量约为3 000 tCO₂。随着可再生能源发电的大规模并网,当电网排放因子降低到0.34 tCO₂/（MW·h）以下时,现有项目方式将不再具有节能减排效应,但是仍可采取项目改造、增加可再生能源供能比例等方式提升碳减排能力。本研究为基于燃气分布式的综合能源系统发展及“双碳”目标的实现提供了良好的理论基础。

Abstract:

Integrated energy system is regard as an excellent power suppler at current stage for its capabilities of horizontally adjusting electric power,heat,cold energy,gas and hot water,and vertically coordinating source,network,load,storage and consumption links.CCER methodology and Guidelines On Enterprises Greenhouse Gas Emissions Accounting and Reporting—Power Generation Facilities provide a calculation method for the carbon emission reduction of gas-based distributed integrated energy systems and the reference system.A carbon emission reduction analysis was made on a gas-based distributed integrated energy system in Beijing.The system worked well in energy saving and emission reduction in current power system for realizing 3 000 tCO₂ emission reduction from 2016 to 2020 annually.With the large-scale grid-connection of renewable energy generators,the greenhouse gas emission factor for grid will drop to 0.34 tCO₂/（MW·h） or below.At that time,the existing system can no longer save energy or reduce carbon emissions,unless the proportion of power supply made by renewable energy can be increased.The study lays a sound theoretical foundation for the development of gas-based distributed integrated energy systems and the realization of "dual carbon" target.

Key words: gas-based distributed energy, integrated energy system, reference system, greenhouse gas emission factor for grid, carbon emissions, carbon emission reduction, carbon neutrality, carbon peak
