Abstract - Objective of this study is to simulate an hybrid
The relation between its renewable energies and the limits of use, with regard to variation of resources and the fluctuation of loads according to annual and daily periods linked to climatic conditions, are the subject of a more general solution at the level of Generation of electric power, one that leads to introduction of hybrid systems, to serve as electric power to telecommunication relays, border posts, isolated housing, dispensaries ... etc
wind-photovoltaic-diesel generator to supply a load in Tamanrasset region, this solution is proposed to overcome defects of zone isolation, Not important and also scattered in this region. Algeria among the countries, which have a very important renewable deposit. However, part of renewable energies in the national energy balance still very low. In this context, work presented in this paper is a contribution to use of hybrid system - Wind-PhotovoltaicDiesel with storage batteries to be installed in Tamanrasset region, in order to reduce greenhouse gas emissions. To validate hybrid system for electrical energy generation, simulation results will be presented by HOMER software based on actual geographical information of studied region.
2. OPTIMIZATION WITH HOMER SOFTWARE For the hybrid system study; We used HOMER software, which was developed by National Renewable Energy Laboratory (NREL) in United States and supports design evaluation of various electrical power generation systems connected to an electrical grid Classic or not, for variety of applications. It allows to analyze and to combine between different sources of energy in order to arrive at displaying an optimal configuration of a system capable of supplying energy to specified site in a feasible manner according to certain technical and economic criteria [3].
Key Words: Renewable Energies, Hybrid System, Homer, solar wind system.
To simulate a hybrid system, all elements of the hybrid system must be defined, using the components defined in the software library such as wind turbines, photovoltaic panels, generators and static converters, etc. If it is necessary to add a component that does not exist in the list of elements defined by default, the software allows us to add it by introducing all its technical characteristics as well as its cost. You can also modify the characteristics of a component already existing in the library.
1. INTRODUCTION Global warming and pollution caused by fossil fuels, which have become harmful to human life. Growth in global electricity demand, thus rapid depletion of hydrocarbons requires use of renewable energies [1] which are nonpolluting, practical and economical. Only 6.4% of total renewable energy sources available in the world are used today as sources of inexhaustible electrical energy. In order to compensate for defects of each energy source, there has been an increasing tendency to combine them with diesel generators, which gives a hybrid system of energy generation.
Also HOMER simulates the operation of a system by making hourly energy budget calculations at each element for 8760 hours in a year. He finds the least expensive combination that meets specific electrical and thermal loads. HOMER simulates several configurations; it optimizes the cost for a given life cycle and generates sensitivity results for most situations.
For isolated sites of conventional power grid, the possibility of being connected with this network remains a major problem to the fact that price of extension is prohibitive in parallel with the increase in fuel prices also. Highlighting the price of generators based on renewable energy are experiencing a steady decline in price at the same time increasing reliability, these benefits have led to significant use of generation of electric power by renewable energies [2].
