Line loss calculation of distribution network is critical to energy saving and comprehensive line loss analysis is an in-depth research for theoretical line loss calculation, which helps to achieve meticulous management of loss management and grid operation. This article describes various methods of line loss calculation and common algorithms. A comprehensive distribution network line loss analysis...
At present, the foreign softwares are mainly focused on calculation, analysis and simulation in the grid design field, which is not designed specifically for the field of distribution network planning. In addition, there are still large differences between the foreign demands in developing ideas, applying habits and the domestic distribution system, resulting in the foreign analysis software has not...
It is an effective measure to reduce voltage distortion and guarantee power quality by allocating active filters in distribute network. The location and parameter of active filters are coded firstly, then the active filter's capacity is calculated through solution variable based on calculation of the harmonic power flow. This ensures the filter's safty operation constraint. The current optimal variables...
The paper analyzes the character of distribution network, utilizes the multi-objective differential evolution algorithm to carry on selecting and location optimization about the automatic equipment, takes switch as code of the chromosome gene, in each evolutionary generation, divides the community into three sub-communities which execute variation, crossover, fitness evaluation and select operation...
