Hybrid renewable energy sources (HRES) — A review

The technique of using renewable resources as the source of generating electrical energy leads to the development of sustainable ecosystem. Hybridizing, (combining more than two renewable energy sources) these resources for the efficient generation of energy in power system is rapidly increasing in the present scenario. For this generation of electrical energy, there are certain factors are to be maintained in particular levels. Finding the factors are by going through some predefined algorithms. This paper leads to summarization of Hybrid renewable energy sources (HRES) usage and co-relative study of optimization techniques.
