弃风供暖模式下风电接纳能力评估及效益分析

Benefit Analysis and Evaluation of Wind Power Integration Capability Based on Abandoned Wind Power Heating Mode

弃风供暖是解决风电接纳难题的有效途径,可缓解"三北"地区弃风严重问题。首先介绍储热式电采暖接纳弃风的运行模式,然后基于时序生产模拟方法建立弃风供暖模式下风电接纳能力评估模型,并以某省级电网为例,对不同电采暖运行模式下风电接纳能力进行评估分析,最后,基于中国现有弃风供暖模式和结算模式,定量分析了热电厂、风电场、电网企业、全社会各方经济主体利益以及全社会碳减排情况。案例分析结果表明,弃风供暖不仅可以提高风电接纳能力,还具有良好的环境效益,但是其提高的风电接纳的空间有限,且除绑定风电场之外的其他经济主体的收益不明显。

It is an effective way to solve wind power accommodation problem by using abandoned wind power for heating recently in ＂three north＂ regions during heating period. Firstly, the operation mode of electric heating for accommodating wind power is introduced. Then, based on time sequential simulation method, an estimation mode of wind power accommodation capability is build. With a certain provincial power grid as an example, the wind power accommodation capability under different operation mode of electric heating is assessed and analyzed. Finally, the related entities economic interests as well as the carbon emission reduction are quantitatively analyzed at existing abandoned wind heating mode and settlement pattern. Case studies presented here show that abandoned wind power heating does help to facilitate wind power integration and environmental benefits. However, due to limited wind power accommodation space, benefits of economic agents other than wind farms are not obvious.
