基于均值出力的风电调峰成本量化方法
摘要：随着大规模风电的快速发展，电力系统的调峰服务需求越来越多，调峰服务的成本也随之增加。合理的计算由风电引发的调峰服务费用是激发常规机组提供调峰服务的前提。为此，提出了风电引发的调峰成本计算方法——风电均值出力参考法，该方法将某时段内风电电量平均分配到各个调度时段得到风电均值出力线，并进一步得到计算调峰成本的参考场景。以此为基准，可直观地计算和体现具体场景中风电出力曲线是否给系统造成了额外的调峰成本。采用所提方法对一个含风电场的5火电机组系统进行了测试，结果验证了所提方法的正确性和有效性。
Abstract:With the rapid development of large-scale wind power, the demand for peak shaving service in power system and the cost of peak shaving service are increasing. Reasonable calculation of peak shaving service cost caused by wind power is the premise for encouraging conventional units to provide peak shaving service. To this end, a quantitative method for calculating peak shaving cost caused by wind power which is called wind power mean output reference method is proposed. Firstly, the wind power output in a certain time period is evenly distributed to each dispatching period for obtaining wind power mean output profile. Then the reference scenarios for peak shaving cost calculation are obtained. Finially, the peak shaving cost in the specific scenarios can be calculated to reveal whether the wind power output curve in specific scenarios have caused additional peak shaving costs to the system. The proposed method is tested on a 5 thermal power units system with a wind farm, and the results verify the effectiveness of the proposed method.
