The non conventional energy sources overcomes the drawback of Conventional energy sources, drawbacks like depletion, increasing cost, global warming etc. Among the all non conventional sources , solar energy is widely used as it can directly convert solar energy solar energy into electrical form with solar photovoltaic cell (PV Cell). Energy produced by PV cell is varying with partially shading...

Many maximum power point tracking (MPPT) algorithms have been developed in recent years to maximize the produced PV energy. These algorithms are not sufficiently robust because of fast-changing environmental conditions, efficiency, accuracy at steady-state value, and dynamics of the tracking algorithm. Thus, this paper proposes a new random forest (RF) model to improve MPPT performance. The RF ...

This paper proposes a novel optimal current given (OCG) maximum power point tracking (MPPT) control strategy based on the theory of power feedback and hill climb searching (HCS) for a permanent magnet direct drive wind energy conversion system (WECS). The presented strategy not only has the advantages of not needing the wind speed and wind turbine characteristics of the traditional HCS method, ...
