OPTIMAL TOPOLOGY OF ELECTRIC CIRCUITS IN PV-PANELS AND PV-PLANTS WITH USING CONTROLLED CONNECTIONS

Abstract

The article considers the topology of electric circuits of photovoltaic panels and photovoltaic plants. The existing principles of connection are considered, advantages and disadvantages are analyzed. A parallel-serial connection cell for connecting two power sources is proposed. It is possible to implement parallel connection, serial connection and shunt, simultaneously, in one device. Switching in this cell is controlled and dynamic. The topology of combining a large number of photovoltaic devices is demonstrated. A topological structure in the form of a tree is used. The advantages and disadvantages of this approach are shown. A modern technological approach to the implementation of such a controlled system is proposed. Conclusions are made.
