There have been global initiatives for the promotion of self-sufficient renewable energy systems. This initiative has led to the development of renewable power generating systems which are capable of providing self-sufficient power generation with the use of more than one renewable source of energy. We can assume that the most commonly used hybrid renewable energy sources in Algeria are solar and wind energies. Climate of Algerian Sahara is hot, sunny and arid. This part of Algeria is a hot desert, located on both sides of a tropic. Daytime temperatures are very high, can exceed 50°C, and the thermal amplitude between day and night is often higher than 350 C or 400C. Addition to this, there is many microclimates which are characterized by very high wind speed. It means that both of wind and photovoltaic energies are widely suitable in this area, especially when we assume that distribution of population is much disseminated. Creating some Microgrids for local consumption will be an interesting solution to provide energy to these populations. But the most important challenge is to provide the best design and management of these systems regarding many parameters such as the location, type of loads, and energy produced cost.
