Abstract
One of the primary goals of modern energy systems is to create a cleaner environment while simultaneously increasing electricity consumption. This requires optimizing the operation of distribution systems and power plants. Grid-connected photovoltaic (PV) systems offer an effective solution to this challenge. This study examines the efficiency of a single-phase inverter integrated with the DigitalEgiz digital twin system, enabling intelligent management and monitoring of photovol-taic solar modules. The objective of this research is to explore new transformer to-pologies, control methods, and the implementation of digital twin technology to enhance efficiency. The proposed approach leverages the DigitalEgiz system to collect environmental data (temperature, humidity) and operational parameters of solar modules (current, voltage, power) while optimizing control based on data analysis. This enables a broader input voltage range and improves inverter per-formance. Laboratory tests demonstrate that a photovoltaic system with a power capacity of 1500 W and a battery capacity of 900 Ah provides daily energy output ranging from 2.5 to 3.2 kWh, with battery discharge times varying between 4.5 to 12.9 hours under a load of 300–1000 W. The integration of DigitalEgiz has in-creased monitoring accuracy, improved battery discharge management, and opti-mized real-time power distribution, offering significant financial benefits in the long term.
