Сценарна оптимізація режимів електричних мереж за критеріями якості електроенергії

Abstract

An approach to scenario-based optimization of electrical network operating modes according to power quality criteria is proposed. It is shown that under modern conditions the optimal operating mode cannot be determined only by minimum power losses or permissible equipment loading. Voltage deviations, unbalance, harmonic distortion, reactive power flows, operation of transformers with on-load tap changers, capacitor banks, inverter-based renewable energy sources, and battery energy storage systems should be considered simultaneously. The feasibility of transition from one-time operating mode calculation to scenario-based control, taking into account changes in network configuration, load profile, and distributed generation composition, is substantiated.
