Abstract
Methodology for predicting solar radiation based on typical days: comparative analysis of average and median profiles
Incoming article date: 12.01.2026The paper presents a physical model of an electric power consumer designed to reproduce the stochastic nature of phase unbalance in daily load profiles of autonomous facilities and to be used as part of a hardware-in-the-loop modeling complex for autonomous power supply systems during the development and tuning of hybrid power plant control systems. The architecture of the complex, including mathematical models of generation sources, control systems, and a physical model of the electric power consumer, is described. An approach to forming an active-reactive load based on discretely switched resistive and inductive elements is proposed, a mechanism for selecting load configurations according to specified operating parameters is implemented, and a method for scaling operating modes based on similarity theory is presented.
