Grid Management Technology for The Integration of Renewable Energy Sources into The Transmission System

Abstract

One of the key issues during the integration of widely spreading renewable energy sources into the electric transmission system is the management of the generated surplus power. There is a new and cost-effective way to handle this problem, the so-called Dynamic Line Rating (DLR). There are several realization options for system implementation, such as soft-computing methods, physical models or the use of overhead line monitoring systems. The aim of this paper is to demonstrate the advantages of the DLR calculation method in case of using mathematical and numerical techniques to manage the issues caused by renewable energy sources integration into the transmission grid.
