Modified Fuzzy Clustering Method for Energy Loss Calculations in Low Voltage Distribution Networks
There is presented a new method for calculation of energy losses in low voltage distribution networks. The method is based on the fuzzy clustering and modified fuzzy clustering techniques, and requires input data that we can collect easily: lengths of lines, number of line segments, number of customers, conductor’s cross section area, conductor’s material, electrical energy delivered by distribution transformers, and peak loadings of distribution transformers. Additional measurements that enable exact calculation of energy losses are required for set of test networks. Presented method is tested on the example of ninety low voltage networks. Optimal number of clusters as well as the optimal value of the parameter m that defines fuzziness of fuzzy clustering was determined.
