Fuzzy Approaches to Distribution Energy Losses Calculation
نویسندگان
چکیده
Two approaches to calculating distribution energy losses are developed in this paper. The first one is based on the fuzzy load flow, and the other one uses fuzzy clustering technique. The attention at the first approach is devoted to forming the fuzzy numbers that represent loads. Data accessible from the measurements in corresponding substations are considered in this process. Using formed fuzzy loads one fuzzy load flow calculation is made. Results of calculation are fuzzy power losses. Defuzzification gives the deterministic value of average power losses that multiplying with the number of hours for analyzed period gives energy losses. For the second approach, the range of the coefficient that defines fuzziness of clustering is determined, as well as an optimal number of clusters. Analyses shows that the best results are obtained for fuzziness coefficient on the range of 1.1-2, and the number of clusters up to 20.

In this paper, an original scheduling approach for optimal dispatch of electrical Energy Storage Systems (ESS) in modern distribution networks is proposed. The control system is based on fuzzy rules and does not use forecasts since it repairs the past history according to the real time data on the electrical energy cost, renewable energy production and load. When the system detects a worsening ...
