摘要
能源结构的改变与电力用户的增加,使得柔性负荷需求特性也随之发生变化,导致电力用户柔性负荷需求影响潜力评估难度越来越大,威胁着电力系统运行与管理的效率与效果,故提出区块链架构下电力用户柔性负荷需求影响潜力评估方法研究。在区块链架构及其技术支撑下构建电力用户柔性负荷需求模型,以此为基础,选取适当的电力用户柔性负荷需求影响潜力评估指标,引入熵值法计算评估指标权重系数,确定最终的柔性负荷需求影响潜力评估模型,制定影响潜力等级划分规则,从而实现了电力用户柔性负荷需求影响潜力的有效评估。实验结果显示:应用提出方法获得的电力用户柔性负荷需求数据完整度最大值达到了98%,柔性负荷需求影响潜力评估结果与实际结果相同,充分证实了提出方法应用性能较佳。
With the change of energy structure and the increase of power users,the characteristics of flexible load demand also change,which makes it more and more difficult to evaluate the impact potential of power users’flexible load demand,threatening the efficiency and effect of power system operation and management.Therefore,a research on the impact potential evaluation method of power users’flexible load demand under blockchain architecture is proposed.Based on the blockchain architecture and its technical support,the flexible load demand model of power users is constructed.On this basis,appropriate evaluation indicators of the impact potential of flexible load demand of power users are selected,and the weight coefficient of evaluation indicators is calculated by introducing entropy method,so as to determine the final impact potential evaluation model of flexible load demand and formulate the rules for the classification of impact potential,thus realizing the effective evaluation of the impact potential of flexible load demand of power users.The experimental results show that the maximum data integrity of power users’flexible load demand obtained by the proposed method reaches 98%,and the evaluation results of the impact potential of flexible load demand are the same as the actual results,which fully proves that the proposed method has good application performance.
