Dynamic Line Rating Solution: Deployment Opportunities for the Power Transmission Grid of Vietnam

Power system usually have standard static ratings (SLR) that determines load constraints. It refers to the maximum allowable conductor ampacity pre-determined by worst-case conditions (high ambient temperature, solar radiation, and low wind speed) of their overhead transmission lines, rises line’s temperature without infringing ground clearance causing loss tensile strength. Line’s dynamic capacity is created as an alternative constant rating designed with reference extreme weather conditions. Dynamic line allows assets real power operating using available information on DLR hence often more flexible than SLR, a chance extending existing lines for some periods time favorable transportation higher electrical from production site load. This paper investigates possibility (DLR) expand which can be implemented 220 kV in Vietnam, especially areas high-density renewable energy integration. work applies caculation models determine lines’ additional theoretical obtained this methodology Ninh Thuan region distinct regarding i) database, ii) topography iii) resource. The results show predominantly rating, potentially enhances system’s reliability. research provides comprehensive study literature current constraints based geography analysis Python Matlab environment real-time databases applied proposed case study.
