Performance investigation of a hybrid PV-diesel power system for remote areas

Abstract

Summary Algeria is in a region with an enormous potential of solar energy for power generation. However, photovoltaic (PV) power plants have not yet been developed sufficiently in the country, and its applications such as PV pumping, solar distillation, and solar heating. The main problem is the high maintenance, operating costs, fossil‐fuel transportation, and CO2 emission of Bordj Badji Mokhtar's (BBM's) diesel power plant that exhibits a noteworthy issue in south Algeria. This paper presents the results of a theoretical and experimental study for PV/diesel hybrid energy system (HES) considering the load demand profile and the solar radiation in isolated area of south Algeria. Suggested hybridization based on a renewable energy with a view to an improved environment is promising. Study results show the performance of PV/diesel system based on solar radiation. The experiment load curve in this typical area may conduct the diesel generator to operate at 60% to 70% of its nominal power with less fuel consumption, and it has been verified during this study that the implementation of a PV/diesel hybrid system is efficient for higher load and higher solar radiation. Results and discussions are encouraging considering less emission of greenhouse gases and less storage of fuel, which drives the government to draw a political arrangement for the improvement of cleaner forms of electricity generation.

Hybrid mobile power supply system of Multimedia Hybrid Mobile Stages

“…The method of harvesting of electric energy from PM with the use of SCB in comparison with analogues works effectively even in rapidly changing weather conditions and monitors the MPP of each module with sufficient accuracy. In the vast majority of analogues [2,3], the search for the maximum power point (MPP) is carried out at the level of sequential PM string. However, it is known that in a string, all solar panels cannot work in the MPP if it is formed by a direct electrical connection of the PM.…”

“…It is possible to increase the efficiency of the MHMS power supply system by means of the Hybrid Mobile Power Supply System (HMPSS). Today, autonomous energy supply systems using renewable energy sources for use in different geographical parts of the world are being intensively studied, both theoretically and experimentally [2] - [5]. However, for remote regions, where the implementation of the central grid is not economically feasible, the best option is to use HMPSS, which contain several sources of electricity generation: usually renewable photovoltaic modules (PM), and traditional -usually diesel generator (DG) [3], [4].…”

“…Among the main reasons that motivate scientists around the world to such studies are the reduction of greenhouse gas emissions through the use of renewable energy sources [2], [6]; ensuring the possibility of power supply to remote regions, taking into account economic (related to the cost of diesel fuel) aspects, reliability and environmental pollution [5] - [7]; providing electricity to rural areas of underdeveloped countries [7]; a reliable source of energy for rapid response teams in remote disaster areas to power a vaccine refrigerator, water purification system and basic satellite communication system [8], which has great potential to save lives.…”

Optimal Configuration Investigation for Photovoltaic Water Pumping System, Case Study: In a Desert Environment at Ghardaia, Algeria

“…Algeria is committed to stabilize and reduce greenhouse gas emissions after the ratification of the Kyoto Protocol in 1997 [2]. The greatest renewable energy sources in Algeria that can reduce the impact of global warming, we can cite, solar, biomass, wind, geothermal, and fuel cells energy [3,4]. They are sustainable, non-polluting and economically viable energies [5].…”

Techno‐economic analysis of photovoltaic‐biomass‐based microgrid system for reliable rural electrification

“…However, the COE from hybrid off‐grid systems is more economical than that from solar home‐only systems or diesel‐only systems . Further, a PV/diesel hybrid energy system was found to be more efficient for higher load and higher solar radiation with a lesser requirement of fuel storage for remote areas of Algeria . In a techno‐economic analysis of a standalone hybrid wind/fuel cell micro‐grid system for the Kouhin region in Qazvin, the capacity factor of the hybrid system was enhanced to 28.8% with a maximum contribution of 90.59% energy supply from wind turbines and 9.41% from fuel cells .…”
