Abstract

Dynamic Line rating can be used as a temporary alternative to manage congestion in networks that have high penetration of renewable generation. Key factors for implementing dynamic line ratings in scheduling and planning are network imbalance constraints. Modern power systems are expected to have some degree of imbalance even at the transmission level due to the presence of embedded generation and uncoordinated electric vehicle charging. This paper presents a new mathematical framework to generalize the extended conic quadratic optimal power flow with dynamic line rating in the context of three-phase load flow formulation. Extended cases were studied and results indicate that the proposed approach can be well fitted to unbalanced operating conditions when each phase of the system is considered separately with mutual coupling between phases. Dynamic line rating (DLR) proved to provide considerable benefits in unbalanced networks with no adverse effects on voltage imbalance.
