Abstract
With the further development of the electricity system, people are more and more emphasis on power quality, Comprehensive evaluation of electricity supply situation and the economic management has been the electricity sector and the user's attention.Evaluation of strengths and weaknesses of power supply situation can directly reflect the rational electricity supply situation and provide a better basis for improved for electricity planning and development in the future.It has practical significances in the Quantitative management of the electricity.
The fuzzy comprehensive evaluation model is applied to the situation of daily electricity supply on the residential area in this paper.By referencing to relevant literature and expert advice it selected the "technical rationality", "running safety", "reliability" and "economic benefits" of these four that those are a total of 20 indicators as evaluation factors set,then established a set of five reviews evaluation-"Excellent", "Good", "General", "Poor" and "Bad".It choosed AHP to determine weights, Obtained at all levels of evaluation matrix according to Matrix, then organized of evaluation results as a new evaluation matrix to judge the daily electricity supply situation on the residential area.
Through using MATLAB to program and using Excel to calculate，the four models by different Composite operators obtained the same results-“Excellent”. The evaluation results are in keeping with reality and have Practical utilities.
Designing the Fuzzy control of residential electricity supply system,Using Fuzzy sets to describe the operation of the actual uncertainty on Zadeh fuzzy reasoning.According to fuzzy IF-THEN rules,obtaining the membership function related to electricity supply, then fuzzy the sets , get the output set By Zadeh inference and turn the Fuzzy sets into real numbers by Ambiguity focus device.
