新电改下考虑微网和多元负荷的配网效益评价研究
|
摘要
随着新电改的不断推进以及微网、多元负荷的迅速发展,在政策与技术的综合背景下如何确保电网公司对配电网投资的综合效益成为关键。针对该问题,综合考虑微网、多元负荷对配网投资的影响,构建了一种配网投入-产出效益评价指标体系;其次,结合微网、多元负荷对购售电的影响建立了新电改后配电网的投入产出模型;最后提出了评分法和优选法2种方法进行配网投资的评价以及配网规划项目的优选,其中评分法采用层次分析法及熵权法确定综合权重,优选法采用改进灰色关联度法进行数据分析。实际算例验证了所提评价体系的可行性及有效性。
With the continuous advancement of new power reforms and the rapid development of microgrids and multiple loads,how to ensure the comprehensive benefits of grid companies' investment in distribution networks is the key to the comprehensive background of policies and technologies. Aiming at this problem,this paper comprehensively considers the impact of micro-grid and multi-load on the investment of distribution network,and constructs a distribution network-input benefit evaluation index system. Secondly,it combines the influence of micro-grid and multi-load on the purchase and sale of electricity. The inputoutput model of the distribution network after the new power reform. Finally,the evaluation of the distribution network investment and the optimization of the distribution network planning project are proposed by the scoring method and the preferred method. The scoring method uses the analytic hierarchy process and the entropy weight method to determine the synthesis. The weighting and optimization method uses the improved gray correlation method for data analysis. The practical examples verify the feasibility and effectiveness of the proposed evaluation system.
