To date, one of the most pressing issues of the electric power industry is the electric network operation efficiency. The problem is associated with a high level of technical losses of electricity, which is the most important indicator characterizing the performance of electric network companies. A method to optimize the electrical network operation mode with respect to the minimum active power loss criterion is considered. The object of the study is a network with three classes of rated voltage. The voltage on the buses to which reactive power sources are connected remains essentially unchanged. This is necessary to take into account operational and technical limitations. Two computational cases are analyzed for the scheme under study. In the first case, the transformation ratios were adjusted by means of all available on-load tap changers. In the second case, the transformation ratios were adjusted only at the last voltage transformation stage. As an outcome, the optimal set of nodal voltages, reactive power source capacities, and transformer transformation ratios were determined. A feasibility study was carried out, as a result of which the electric network optimal state was found not only in terms of the minimum active power loss criterion, but also taking into account the reimbursement of costs for the operation mode implementation and technological constraints. Conclusions are drawn about the influence of reactive power sources on the active power loss in the network and about the dependence of the optimization result on the composition of available equipment. The obtained results may be applied in designing electric power systems and planning their operation modes.
