摘要:

针对当前大规模可再生能源发电接入电力系统所带来的可再生能源消纳的问题,提出了一种城市可再生能源消纳能力的量化方法和基于虚拟电厂的消纳能力提升措施。首先,对可再生能源消纳的问题进行分析,对虚拟电厂的基本概念进行详细阐述;其次,针对风力发电和光伏发电,从调峰裕度的角度对其消纳能力进行量化分析,提出弃风、弃光时间和弃风、弃光量2个方面的风电、光伏消纳能力量化分析方法;最后,提出利用电动汽车和柔性负荷提升城市可再生能源消纳能力的方法,并通过详细的算例验证了该量化方法和提升措施的有效性。

Abstract:

In order to address the problem of renewable energy accommodation caused by the integration of large-scale renewable energy power generation into the power system, we proposed a quantitative method for the accommodating capacity of urban renewable energy, and a method to improve the accommodating capacity based on virtual power plants. Firstly, the issue of renewable energy accommodation, and the basic concepts of virtual power plants were introduced. Then, for wind power and photovoltaic power generation, a quantitative analysis of absorption capacity was proposed from the perspective of peak shaving margins. Moreover, the quantitative analysis method of accommodating capacity was developed based on the time of abandonment and the amount of abandonment. Finally, a method of using electric vehicles and flexible loads to improve the absorption capacity of urban renewable energy was proposed and further verified by case studies.

Key words: power system, virtual power plant, renewable energy, electric vehicle, flexible load
