【摘要】：随着节能技术的快速发展和我国在政策上对配电网节能减排的不断重视,国家对节能降损的研究进入了快速发展时期。节能降损方案的广泛应用在一定程度上大大降低了配电网损耗,但由于不同节能技术的特点,对节能方案的评价不仅仅需要考虑节电效果,同时也应考虑对配电网安全性和经济性的影响因素。因此,研究综合评价配电网节能潜力的各项指标,形成完善的节能潜力综合评价方法,对挖掘配电网整体节能潜力具有重要意义。本文首先研究了现有配电网单一节能技术的机理和节能潜力评价方法,然后深入讨论了多层次模糊评估法的基本原理和分析步骤。在此基础上,考虑影响配电网节能潜力的综合指标,从节电效果、电网安全性和经济性这三个角度共同评价节能方案的节能潜力大小,最终形成了体系化的基于多层次模糊评估方法的配电网节能潜力综合评价方法。最后以IEEE36节点配电网为实例,运用本文提出的评价方法,得出不同方案的节能潜力综合评估值,再通过MATLAB软件对不同的节能方案节电效果进行仿真,观察综合节能潜力,评价方法与仿真所得结论一致,验证了该方法的有效性与可行性。本文所提出的配电网节能潜力综合评价方法,综合考虑影响节能效果的各个因素,量化了节能方案的节能潜力,对形成配电网优化改造措施,降低损耗将起到至关重要的作用,也对提高配电网运行的安全性与经济性具有重要意义。
[Abstract]:With the rapid development of energy-saving technology and China's policy in the distribution network energy conservation and emission reduction attention, The national research on energy saving and loss reduction has entered a period of rapid development. The widespread application of energy saving and loss reduction schemes has greatly reduced the distribution network losses to a certain extent, but due to the characteristics of different energy-saving technologies, The evaluation of energy-saving scheme should not only consider the effect of saving electricity, but also consider the factors that affect the safety and economy of distribution network. Therefore, the indexes of comprehensive evaluation of energy saving potential of distribution network are studied. It is of great significance to form a perfect comprehensive evaluation method for energy conservation potential of distribution network. In this paper, the mechanism of single energy saving technology in distribution network and the evaluation method of energy saving potential are studied firstly, then the basic principle and analysis steps of multi-level fuzzy evaluation method are discussed in depth. Considering the comprehensive indexes that affect the energy saving potential of distribution network, the energy saving potential of the energy saving scheme is evaluated from the three aspects of power saving effect, power grid safety and economy. Finally, a comprehensive evaluation method of energy conservation potential of distribution network based on multi-level fuzzy evaluation method is formed. Finally, taking the distribution network of IEEE36 node as an example, using the evaluation method proposed in this paper, the comprehensive evaluation value of energy-saving potential of different schemes is obtained. Then the power saving effect of different energy saving schemes is simulated by MATLAB software, and the comprehensive energy saving potential is observed. The evaluation method is consistent with the simulation results, and the validity and feasibility of the method are verified. In this paper, the comprehensive evaluation method of distribution network energy saving potential is put forward, considering all the factors that affect the energy saving effect, the energy saving potential of the energy saving scheme is quantified, and the optimized transformation measures of distribution network are formed. Reducing loss will play an important role in improving the safety and economy of distribution network operation.
