The state-of-the-arts of the study on grid interconnection between Iberian Peninsula and West Maghreb region

Abstract With the change of energy structure in Europe and the trend of diversification of energy supply, the interconnection of the power grid in the Mediterranean region has gradually become a hotspot in European energy research. This paper introduces the power supply, load demand, power grid construction and the present situation of multinational interregional interconnection in the Iberian Peninsula of the Tour of Mediterranean in Europe (Portugal and Spain) and the Western Maghreb countries (Morocco and Algeria). And the driving force and influence factors of regional power grid interconnection are also analyzed. According to the MEDGRID project aimed at realizing the Mediterranean power grid interconnection, this paper presents the interconnection schemes of the Iberian Peninsula and the Western Maghreb. Furthermore, the subsequent technical problems need to be solved are also expounded.
