| Interface entre les sources d'énergies renouvelables ou les sources d'énergie réparties et les systèmes d'alimentation électrique en courant continu jusqu'à 400 V |
Les solutions d'alimentation électrique en courant continu jusqu'à 400 V pour les équipements de télécommunication/TIC, telles qu'elles sont définies dans la série UIT-T L.1200, sont bien adaptées à l'utilisation directe d'énergies renouvelables ou de sources d'énergie réparties par le biais de nouveaux nano ou micro-réseaux électriques simples en courant continu. La Recommandation UIT-T L.1205 définit le couplage des sources locales ou éloignées d'énergies renouvelables avec les systèmes d'alimentation électrique en courant continu jusqu'à 400 V, sans réduire les performances des systèmes en courant continu définies dans la Recommandation UIT-T L.1202, principalement en termes d'efficacité et de fiabilité. Les principaux avantages sont une diminution de la consommation de combustibles fossiles (source de consommation d'énergie primaire), une réduction des émissions de gaz à effet de serre et une résilience accrue. L'interconnexion de sites supplémentaires à un réseau électrique en courant continu peut apporter encore plus d'optimisation. Un autre avantage important est que, par rapport au courant alternatif, un courant continu de 400 V ne nécessite pas de synchronisation entre les différentes entrées, ce qui permet d'avoir une architecture simple. |
