Fossil Fuels are always considered as environmental pollutants. On the other hand, the political and economic situations highly affect the price of these fuels. Offshore wind and wave, as renewable energy sources, represent the better alternatives for electricity generation. Therefore, it is necessary that wind speeds effectively be estimated due to the absence of field measurements of the wind...

In the last years, there are several studies and researches in literature about hybrid Maximum Power Point Tracking (MPPT) Methods have been performed to obtain efficient systems. Hybrid systems uses renewable energy sources features of these be known apply suitably. this article, mentioned sources, MPPT methods explained review results given with tables also, compared.

A hybrid Energy Storage Systems (ESS) consists of two or more energy storage technologies, with different power and characteristics. Using a ESS, both high-frequency low-frequency variations can be addressed at the same time. For an accurate sizing use high-resolution data is required. However, over long periods leads to large sets, which are difficult handle. In this paper, improved motif disc...
