采取电采暖方式消纳清洁能源的综合效能分析

Comprehensive Efficiency Analysis on Clean Energy Accommodation with Electric Heating

摘要:

随着清洁能源大量广泛开发利用，受各种因素的影响，清洁能源弃电严重，特别是北方冬季采暖季节，受供热 机组供热的约束，供热火电机组占用了清洁能源消纳的空间，采用电采暖方式一方面减少供热机组约束，扩大消纳清 洁能源空间; 另一方面也提高环境保护能力。但采用电采暖方式，属于二次能源再利用，存在多方面因素的效能评估。 针对城市电网电采暖供电方式，开展了电采暖与燃煤( 燃气) 采暖的技术经济比较，对采用电采暖可行的几种方式也 进行了分析，提出了采用电采暖方式需关注的方面，对电采暖的推广和提升城市清洁化水平提供借鉴意义。

Abstract:

With the extensive development and utilization of clean energy and affected by various factors，clean energy has been abandoned seriously，especially in the winter heating season in the north． Ｒestricted by the heating of co － generation units，the thermal units for heating supply occupy the space of clean energy accommodation． On the one hand，the electric heating method reduces the constraints of co － generation units and expands the space of clean energy accommodation，on the other hand，it is also environmentally friendly． However，there exists many factors of effectiveness evaluation in using electric heating which belongs to the secondary energy reuse． Aiming at the power supply mode of electric heating in urban power grid， the technical and economic comparison between electric heating and coal － fired ( gas) heating is carried out，several feasible modes of electric heating are analyzed，and some aspects that need to be paid attention to in using electric heating are put forward，which can provide a reference for the promotion of electric heating and the improvement of urban cleaning level
