Minimization of Losses in Electric Networks by Optimization of Transformer Ratios

Abstract

Minimization of losses in electric networks due to the regulation of their modes provides for determining
the optimal values of reactive powers of regulated sources, voltage of reference nodes and transformation
ratios of regulated transformers in circuits. At present, there are many methods and algorithms for
optimizing reactive powers and node voltages that are reflected in the works of many authors. At the
same time, despite the existence of a number of works, the development of more advanced algorithms for
optimizing the transformation ratios of loop transformers, which ensure minimal losses due to the forced
distribution of power flows in closed networks, remains an urgent task.
In this paper, we propose an effective algorithm for minimizing losses in closed electrical networks by
optimizing the transformation ratios of adjustable loop transformers taking into account all types of
restrictions. The results of a study of the effectiveness of the proposed algorithm on a typical example are
presented.
