Abstract
Introduction. The paper considers a power supply scheme for an industrial refrigeration enterprise in the Fergana Valley based on a 297kW grid-connected photovoltaic power plant. The study is aimed at reducing electricity consumption from the external grid, ensuring reliable supply of refrigeration loads, and meeting power quality requirements. The calculations show that the annual generation is 445MWh, the specific yield is 1498kWh/kW·year, the capacity factor is 17.1%, and the load coverage share reaches 23.4%
Methods and materials. The research object is an industrial refrigeration enterprise located in the Oltiariq district of the Fergana region. The system includes 540 PV modules rated at 550 W, three 100 kW inverters, a 0.4/10 kV 1000 kVA transformer, protection devices, and a SCADA/ASU TP monitoring system. The assessment was carried out using integral and balance-based methods.
Results. The annual generation amounted to 445MWh, while the average equivalent power reached 50.8 kW. Against the enterprise’s annual electricity consumption of 1.9 GWh, the solar generation coverage share reached 23.4%. The overall efficiency of the energy conversion chain was estimated at 93%, while losses were about 7%.
Conclusion. The integration of a 297kW grid-connected photovoltaic power plant into the energy supply system of an industrial refrigeration enterprise is technically and energetically feasible. The proposed solution reduces electricity intake from the external grid, ensures reliable operation of critical refrigeration loads, and provides a basis for further system improvement.
