Abstract.Most of world's electric power systems are now widely interconnected involving inter-regional and international connections. The purpose is to achieve better efficiency in generation and transmission of energy. We need these interconnections to take advantage of diversity of loads, availability of sources and fuel price to supply electricity at minimum cost with a required reliability. In addition to the existing interconnections, namely those of the Maghreb, Algeria is Already interconnected to Tunisia (4 connections) and to Morocco (2 connections). But a direct interconnection with European countries around Mediterranean Sea will be open up new opportunities to both partners for economic and technical reasons. Since 2002, Algeria has a new politic to diversify international exchanges. A great number of studies of Interconnection Algerian-Spanish network project have been done by many organisations. Furthermore with the HVDC and VSC-HVDC technology, who allowed DC transport, this interconnection, can be achieved with high reliability. But there is the constraint that Maghreb countries networks are weak in comparison with Spanish one which is robust, and strongly interconnected with European network. In order to give some elements of solution to realise this project, real time simulators of grids are an interesting tool. These simulators are used to simulate grids and electrical equipments with input/output signals to interact with real equipment. In this article, we present different HVDC and VSC-HVDC models, and we will define the best adaptive one to real time simulation, and results obtained with EMEGASIM of the RT-LAB platform.

This work presents an assessment of the wind potential and a design methodology for a 10 MW wind farm in the Arzew industrial region, located in northwest Algeria, to improve the quality of service of the electricity grid and increase Algeria's participation in the use of renewable energy. The hourly wind data of 10 years (2005-2015) that correspond to the wind potential of the site were analyzed, such as: dominant wind directions, probability distribution, Weibull parameters, mean wind speed and power potential. The site has a mean annual wind speed of 4.46 m/s at 10m height, and enough space to locate the wind turbines. A comparative study was carried out between four wind turbine technologies to improve the site's efficiency and select the appropriate technology: PowerWind 56/ 900 kW, Nordex N50/800 kW, Vestas V50/850 kW, NEG-Micon 44/750 kW. The estimate of the energy produced using WAsP software and the choice of the optimal architectural configuration for wind turbines installation was confirmed. A techno-economic and environmental study was carried out by HOMER software, to choose the model that produces the maximum annual net energy with a competitive cost in the global wind energy market, $ 0.068/kWh, and that provides clean energy with a reduced emission of polluting gases. Finally, this work provides a good indicator for the construction of a wind farm in Arzew. ©2020. CBIORE-IJRED. All rights reserved
