ABSTRACT
The aim of this paper is to present an approach to economically improve the overall performance, dependability, reliability and availability of electricity generation power plants in south of Algeria by integrating renewable energy. A prefeasibility study of a hybrid 9x1.9MW Diesel power generation plant in Tindouf (Algeria) from conventional (e.g. Diesel fuel) and renewable energy sources (e.g. wind energy conversion and photovoltaic power generation) will help to improve the performances while paying attention to flexible design, fast implementation, energy efficiency and low emissions. The challenge of such systems is the mitigation of CO2 emissions and reduction of fossil fuels dependency. The integrative character of the engineering approach is illustrated by Tindouf case-study for electricity production in Algeria from hybrid fossil/renewable energy conversion from Diesel engine, PV and wind energy conversion (WEC). Power production should be implemented on site employing appropriate technologies and making best use of local resources of energy, material and labor.
HOMER simulation & results
The renewable energy as well as conventional power generating technologies can be modeled through HOMER. Graphical results help identify market opportunities and barriers for each micro power technology. HOMER helps determine how different conventional, renewable, and hybrid systems interact with end-use demand. three simulations were performed by keeping the same configuration shown below, and introducing changes in the number of wind turbines and power diesel generators and a comparison is made between the three simulations.

Greening a fossil fuel power plant of Tindouf
We call also greening fuel power plant the hybridization of power plant that mean integrating green sources of energy with fuel power plant to become a hybrid system. We will then according to the use of these systems the following advantages:
System operation without interruption.
Fuel consumption reduction through the use of renewable sources.
Ability to preserve the surplus energy produced by the system.
Security of supply whatever the weather.
So that the following disadvantages:
Higher investment due to the extra costs incurred by renewable systems storage and power conditioning.
Solar panels and wind turbines are too expensive and the cost of production of power by their use is generally higher.
Conclusion
Greening the fossil fuel plant illuminate the different ways to reduce the consumption and transport of fuel. HOMER software was used to determine the optimum hybrid configuration. The different simulations in this work allowed choosing an optimum system that can operate in different conditions also that can cover the load while minimizing the consumption of fuel, with a lower price of kilowatt/h. From these results we can say that the project of the hybridization of Tindouf’s diesel plant with wind and photovoltaic can minimize extra costs reaching the consumption of diesel and maintenance of diesel generators.
INTRODUCTION
South of Algeria (Sahara) is known by its large area it represent 87% of 2.4 million km² the area of Algeria, with a population that does not concentrate in a single place which poses a big problem for connection to the power grid, the south of Algeria is powered by diesel power plants, which sooner or later faces constraints such as the depletion of fossil fuel resources, the routing difficulty of these fuels on the places of business for diesel power plants, the cumulative damage to the environment, etc.
With current technologies and their future development, renewable energies, which have the enormous advantage of being sustainable and clean, can help overcome these constraints.

The various studies undertaken on the solar energy potential in Algeria show very significant energy quantities for the operation and use of solar energy. Estimates made on the basis of data from existing weather stations show that the average annual sunshine duration varies from 2600 hours to 3800 in Northern hours in the highlands and the Sahara. In Algeria, the wind speed is low in the north of the country but becomes stronger in the southern regions.

fuel power plant of south Algeria
Diesel plants are located in inaccessible areas, which consequently make it difficult to supply fuel, exploiting the movement of personnel and transportation groups for any overhauls and repairs, of course, can be done on site. Furthermore, the operation of these plants is facing high specific fuel consumption (2.6 to 4.8 th / kWh) of fuel (diesel). In our study we take the case of Tindouf power plant one of the further plants in Algeria
