Diesel Solar Hybrid Power Solutions for Construction and Remote Areas

 

Diesel Solar Hybrid Power Systems

 
 
 
 


Diesel – Solar Hybrid system based on photovoltaic is considered an effective option to electrify remote and isolated areas (e.g. construction site) far from grid. This is true for areas that receive high averages of solar radiation annually. Using diesel generator as a standby source will make utilization of hybrid systems more attractive.

It is found that electrifying rural small community using this Diesel–Solar hybrid system is very beneficial and competitive with other types of conventional sources as it decreases both operating costs and pollutant emissions.

Different types of renewable energy sources are nowadays used to supply different applications in rural and urban areas & construction sites. Increased reliability and energy security issues are of the most benefits that can be achieved by using Diesel-Solar hybrid renewable systems. Diesel-Solar Hybrid systems that depend on photovoltaic (PV) are considered the most popular among other types of renewable systems. The main advantages of this technology are their low maintenance costs and low pollutant emissions.

The block diagram of this system is shown in Figure below. The type of the Diesel-Solar hybrid system and its configuration depend mainly on the availability of the renewable source in the location selected for installing this Diesel-Solar hybrid system. For the  areas, with average daily solar radiation intensity on a horizontal surface 5.6 kWh/m2, these values are relatively considered high and very encouraging for using PV generators.

 

 

 

 

 

 

 

 

 

 

 

 

Optimization OF Diesel – Solar Hybrid Power System

Optimization of sizes of different components constructing the hybrid system is one of the important issues that shall be considered while designing this system. Maximizing utilization of the renewable source, minimizing the cost of generating energy and minimizing the pollutant emissions are objective functions of this optimization. It is concluded that a PV/diesel generator hybrid system is the more feasible system compared to a diesel generator system or standalone PV system for most of cases.

An economic feasibility study is recommended to be conducted for design of a Diesel-Solar hybrid system consisting of photovoltaic (PV) panels, a diesel generator as a backup power source and a battery system. A simulation program using iterative approach is developed to optimize the sizes of PV system and battery bank. Specifications of the hybrid system components are then determined according to the optimized values. Solar radiation data is firstly analyzed and the tilted angle of the PV panels is also optimized. Costs of different components, hourly solar radiation and ambient temperatures and other design considerations are inputs of the simulation program.

Software are available to optimize a suggested PV/diesel hybrid system. It is concluded that the most optimal configuration in for the scenario that involves PV and diesel. A similar study done for a village in Saudi Arabia, and suggested many configurations of the desired system using different types and sizes of components to select the optimal one. In software, different components making the hybrid system can be modeled, studied, specified, and chosen appropriately to minimize the system cost.
