energy concurrently while in sequential mode they produce
electricity alternatively [4,5].
The significant characteristics of HRES are to combine two or
more renewable power generation technologies to make proper
use of their operating characteristics and to obtain efficiencies
higher than that could be obtained from a single power source.
This paper presents a review of solar–wind hybrid renewable
energy system covering issue such as pre-feasibility study,mod-eling, controlling,optimization technique,reliability and power
quality of the system [6]. Fig. 1 presents a basic component of
solar–wind hybrid renewable energy system.
