摘要
传统调峰方法只关注电力需求而忽视发电成本与能源类型等因素,导致高比例新能源微电网调峰效果不佳,因此研究基于优先级排序的高比例新能源微电网调峰.首先通过建立高比例新能源微电网数学模型来确定微电网运行中参与调峰的发电机组;然后以机组调节容量为指标对参与调峰的发电机组进行优先级排序,并依据优先级排序结果控制机组出力,从而实现高比例新能源微电网的调峰.实验结果表明,使用该方法调峰后高比例新能源微电网日负荷峰谷差相比调峰前降低了 405.79 kW,调峰效果较好.
Abstract
Conventional peak shaving methods only focus on electricity demand and ignore factors such as generation costs and energy types,resulting in unsatisfactory peak shaving utility for microgrids with high proportions of new energy sources.Therefore the present work studies a priority sorting-based peak shaving method specific for this case.First by es-tablishing a mathematical model of a new-energy-source-rich microgrid,the generator units involved in peak shaving dur-ing microgrid operation are determined.Then the power generation units participating in peak shaving are prioritized based on the unit regulation capacity,and the output of the units is controlled according to the priority ranking results,thereby achieving peak shaving of the microgrid.The experimental results show that the designed method has obvious peak shaving utility as it reduces daily load peak valley difference of new-energy-source-rich microgrid by 405.79 kW compared to the value with no peak shaving.
