Two-bladed wind turbines (WTs) are recently discussed as a potential alternative to reduce the cost of energy in offshore wind farms which have a higher cost compared to onshore wind farms. However, the dynamic response and performance of these WTs a

The performance of a photovoltaic (PV) system is significantly affected in snowy conditions. Snow accumulation on a PV module causes the shadow on the module and as a result the irradiance level received by the module and its generated power are redu
