基于配额制的自备电厂参与新能源消纳日前交易模式

Day-ahead Trading Model for New Energy Consumption with Participation of Self-generation Power Plants Based on Renewable Portfolio Standards

国内风电和光伏等新能源发电迅速发展,而部分地区本地消纳和电网外送能力均有限,当地自备电厂未充分发挥调峰作用,出现日趋严重的弃风弃光现象,因此难以完成配额制目标。为利用市场手段充分调动当地自备电厂参与新能源消纳,促进新能源配额制目标的完成,同时避免因强行完成指标导致的社会整体消纳成本升高的问题,提出了一种基于竞价摘牌的新能源日前交易模式。通过具有引导效应的市场化手段,调动具备自备电厂用户的主动消纳意愿,进而提升配额制目标完成度,并降低整体消纳成本。最后,以新疆地区算例为例,分析验证了所提交易模式在提升配额制目标完成度及在尽量降低社会整体消纳成本方面的价值,为新疆等类似地区电力市场建设提供了一种新的思路。

There is a rapid development of domestic wind power,photovoltaics and other new energy power generation,but the local consumption and grid transmission capacity in some areas are limited,local self-generation power plants have not fully played the role of peak shaving,and the phenomenon of wind curtailment and photovoltaic curtailment is becoming more and more serious.So it′s difficult to achieve quota targets.In order to use market means to fully mobilize local self-generation power plants to participate in new energy consumption and promote the completion of new energy quota targets,and at the same time to avoid the problem of increased social consumption costs caused by forcibly fulfilling targets,a day-ahead trading model of new energy is proposed based on bidding and delisting.Through market-oriented means with a guiding effect,the willingness of users with self-generation power plants is mobilized to increase the completion of quota targets and reduce overall consumption costs.Finally,taking Xinjiang region for example,the value of this transaction model in improving the completion of quota targets and minimizing the overall cost of social consumption is analyzed and verified,which provides a new way for the construction of power markets in Xinjiang and similar regions.
