摘要
"标杆电价"计价方式难以准确反映新能源发电出力的随机性与波动性给其并网系统运行带来的辅助服务费用激增影响。为此,综合分析电网辅助服务机理,建立区域电网新能源发电导致的辅助服务费用计算模型;考虑各新能源电厂出力波动与区域电网新能源发电综合出力波动之间的关系,建立新能源电厂导致的辅助服务费用分摊模型;进而建立一种基于辅助服务费用分摊的新能源电厂并网价格动态计算模型,给电力市场环境下拟并网新能源电厂的选择及调度计划的制定提供依据。最后,以我国西北某新能源高渗透电网运行数据为例,仿真验证了所提方法的可行性。
It is difficult for"benchmark pricing"to accurately reflect the impact of randomness and fluctuation of renewable energy output on the ancillary service cost(ASC)surge of its grid-connected system.Therefore,on the basis of comprehensive analysis of auxiliary service(AS)causes for power grid,a calculation model of ASC brought by renewable power generation grid connection is established.And then,considering the relationship between output fluctuation of each renewable power plant(RPP)and that of all renewable energy output in a regional grid,a ASC allocation model for RPP is built,and a dynamic tariff calculation method of RPP based on ASC allocation is proposed.This method could provide a base for selection and dispatching plan formulation of RPP intended to connect to grid.Lastly,based on the data of a regional grid with high renewable energy penetration in Northwest China,feasibility of the proposed method is verified with simulation.
