- Abstract
This study presents the development, design and performance analysis of a multistring bidirectional solar inverter connected to the grid (BSICG). An algorithm for the independent global maximum power tracking was both developed and implemented, which produced a system immune to non-uniform irradiation conditions with the aim of applying such on DC (direct current) microgrids connected to a conventional AC (alternating current) grid on the BSICG, which is characterised by bidirectional power flow management. The main advantage of this proposal is thus highlighted as the stabilisation of the voltage on the DC bus even when confronted with irradiance intermittencies from photovoltaic solar energy. All theories are presented and corroborated through experimental results obtained from a 2.0 kW prototype.
