Abstract Energy efficiency technology for constant temperature-controlled logistics centers, which use a lot of power, is becoming a problem as the e-commerce market and logistics sector expand quickly. Several power conversion systems, including Low Voltage Direct Current (LVDC), Energy Storage System (ESS), and Uninterruptible Power Supply (UPS), can be set up as the center’s power devices for energy efficiency, power quality, emergency power supply, and distribution efficiency. Photovoltaic (PV) systems can also be used in light of the Renewable Electricity 100 (RE100) initiative, which intends to use all electricity from renewable energy sources by 2025. In order to address the issue of power loss that arises in numerous power conversion systems, we present in this work the creation of an integrated multi-power conversion system that combines PV, ESS, LVDC, and UPS.
