Abstract
The structure and algorithm of the voltage and reactive power control system for distribution networks with on site power sources containing fuzzy logic controller (FLC) is presented. The controlling parameters are: the transformers voltage ratio and capacities of the reactive power sources \({{{Q}}_{{i}}}\) in distribution networks. The placement of reactive power sources, their values and also transformers regulator’s positions are determined using traditional methods of optimization for selected networks. The structure of reactive power sources and transformers voltage ratio control system containing the fuzzy logic controller is presented in this paper. The problem of optimal correction of transformers voltage ratio and power sources at time of their deviation from the preset values to minimize losses in studied network and maintaining of nodes voltages on the necessary level is considered. The algorithm of membership function formation for input variables of FLC to control/correct capacitors value is shown. Modeling results for real electrical circuit, Q correction in nodes and transformers impact on losses and voltage profile in studied network are presented.
