Analysis of the Impact of Reactive Power Compensation on the Electric Power Quality of the LV Consumers in Distribution Networks of Various Characteristics

In various distribution networks, reactive power compensation can have different effects on voltage conditions and the quality of consumer voltage, depending on factors such as the configuration and parameters of the distribution network, parameters of distribution transformers, consumers load level, etc. This paper presents an approach that, for different types of networks and different consumer load levels, recommends an approach for reactive power compensation in the distribution network. The approach is based on entering the data on the configuration and parameters of the distribution network and load level conditions for each analyzed network. The optimization algorithm proposes different values for the installed power of the reactive power compensation device. The voltage conditions for different intervals of the day are then calculated. The algorithm then evaluates the proposed compensation solution based on the evaluation of voltage variations on the LV side of the transformer for a period of one day. After a predefined number of iterations, the algorithm ends and proposes a solution for the analyzed case.
