Recently, there was a great focus on integrating renewable energy sources (RESs) into electrical power systems (hybrid systems) due to their many environmental and economic advantages. The output of most these RESs is DC; some electronic devices, including inverters, must be used integrate the grid. Any maloperation, faults, or improper control in devices will enormously affect hybrid systems’ performance. This paper aims mitigate misfire fire-through faults that occur at switching inverter...

Renewable energies play an indispensable role in remote areas where the electricity grid is not accessible. Photovoltaic energy (PV), wind and biomass have been included among most of renewable sources. Hybrid systems are considered pragmatic solution for off-grid. Combination between these to expedient load requirements with reliable, economical sustainable supply as a critical concern. This paper reflects techno-economic analysis hybrid power network new Community Egypt, EL-Farafra Oasis...
