Electricity is the important factor for industrialization, urbanization,
financial growth of any country [1]. There are different types of
conventional and non-conventional energy sources used to generate
electricity. Solar and wind energy system is one of the most prominent
sources of energy. The utilization of solar and wind energy
system has become increasingly popular due to modular and environment
friendly nature [2]. The field of solar–wind has experienced a
remarkable growth for past two decades in its widespread use of
standalone to utility interactive solar–wind systems [3].
Solar and wind energy system works normally in standalone or
grid connected mode, but the efficiency of these sources is less due
to the stochastic nature of solar and wind resources. The hybrid
renewable energy sources with grid integration overcome this
drawback of being unpredictable in nature. Hybrid renewable
energy system (HRES) is a combination of renewable and conventional
energy source, it may also combine two or more
renewable energy sources that work in standalone or grid connected
mode. The HRES that combines solar and wind energy key
resources, operates in two modes: simultaneous and sequential. In
simultaneous mode, the solar and wind energy system produces

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, modeling,
controlling, optimization technique, reliability and power
quality of the system [6]. Fig. 1 presents a basic component of
solar–wind hybrid renewable energy system
