Photovoltaic (PV) is an important source of reliable sources of photovoltaic power generation equipment and electrical systems. A PV generator with bilateral isolated converter is used to connect the PV generator to the energy storage system. For comparable loads, the grid coupling system uses a smaller method than a single photovoltaic array. To solve this problem, a new transformer coupled dual input converter with an independent two-phase scheme is proposed. Consider different operating systems for grid-connected and island-like conditions to meet the need to maintain a constant DC voltage. The proposed control enables the micro grid to improve its ability to use photovoltaic power generation under different operating conditions and provide a smoother transition time between grid connections. DC voltage is used to coordinate the switching power and storage of the system under different operating conditions of the communications connection. When the system is independent, the AC power of the converter is used to balance the natural and active power to ensure a constant DC voltage. © 2020 Elsevier B.V., All rights reserved.
