Abstract
The increasing concern about global warming, the upsurge of oil prices, and pollution of petroleum energy has led scientists to search for cost-effective energy sources, for example, photovoltaics. Recently DC microgrids have also drawn more consideration because of the expanding use of direct current (DC) energy sources, energy storages and loads in power systems. First, as a groundwork, the 1D organic solar cell has been investigated that leads to design 3D organic solar cell. Then design and analysis of a standalone solar PV system with dc microgrid has been proposed to supply power for both DC and AC loads. The proposed system comprises of a solar PV system with boost DC/DC converter, Incremental conductance (IC) MPPT, bi-directional DC/DC converter (BDC), DC-AC inverter and batteries. The proposed bi-directional DC/DC converter (BDC) lessens the component losses and upsurges the efficiency of the complete system. Additionally, an intelligent control technique has been proposed using fuzzy logic control to the MPPT control for effective operation under non-linear parameter variations for a nanogrid system. Furthermore, a stability analysis of our DC microgrid system is carried out with a boost converter and a bidirectional DC-DC converter and finally, the Lyapunov function for the system has been proposed.
