According to the growth of energy demand, the increase of the world’s population, and environmental problems, fossil fuel resources cannot be an authentic energy source to provide the required energy. This issue has caused researchers to focus on other sources of energy such as renewable energies. Increases in electricity generation from all renewable sources should push the share of renewables in the electricity generation mix to an all-time high of 30% in 2021. Energy supply has always been a critical issue, and numerous studies have been conducted using various components. For example, using diesel generators in remote and rural areas in conjunction with solar panels and batteries is more cost-effective than a single diesel generator system.

One of the main problems with using renewable systems such as wind and solar as a single supplier is the unreliability of output energy due to the instability of these resources at different times and site locations. Integrating energy technologies to create a hybrid renewable energy system, to increment performance is a viable solution for this issue. Generally, hybrid renewable energy systems are a combination of one renewable energy resource with one or more other resources, which can be grid-connected (on-grid) or stand-alone (off-grid). The use of these systems offers many advantages, including reduction of environmental pollution, high efficiency, and reliability, which are considered essential characteristics.

Electricity supply for remote areas with no access to the grid is one of the most significant challenges. Also, maximum 20% of electricity produced by power plants is destroyed via long distances. Moreover, the development of electricity transmission lines would create high costs for the government. Therefore, hybridization of renewable resources is an appropriate option to increase energy availability, life quality and reduce the cost of energy for the government in these areas. So, applying the renewable resources is feasible for small scale load applications such as, residential areas, small villages, rural areas, hospitals, hotels, and large scale load such as holy shrine, residential complex, and malls. Depending on the study area, the amount of the load demand, and reliability, renewable energies can be applied stand – alone or grid connected. For applying each proposed energy configuration, the techno – economic – environmental feasibility may be investigated. Correspondingly, the values of energy (or exergy) wasting, overall cost, and greenhouse gas emissions associated with each energy system must be low as much as possible.
