The project aims to connect major stakeholders of the energy value chain and demonstrate integrated hardware and software solutions that will facilitate the "unlocking" of the resources for the crossborder electricity flows and regional cooperation. AB - Dynamic line rating (DLR) is a cost-efficient method to increase transmission line transfer capacity. Its techno-economic advantages have already been presented in numerous scientific papers. At the same time, limited operational experience and financial calculations are available concerning such line monitoring projects. This paper aims to give a cost-benefit analysis of a DLR system. The costs and economic benefits of a pilot DLR project in Hungary support the theoretical concept. The paper discusses the financial indicators, capital and operating expenditures, and benefit elements in detail. The quantified and non-quantified benefits are handled separately. As a result of the calculation, it is possible to determine the viability of a DLR project. The paper's key finding is that a financially supported pilot DLR project can ensure both technical benefits and financial return on investment. © 2023 IEEE.

The presented anti-icing system operated continuously for two years. As a part of the project, 4 line monitoring sensors and 2 weather stations were installed on that section of the power line where icing is most likely to occur. These sensors worked continuously and reliably during the demonstration period. The sensor measurements were supplemented with the load value from the SCADA system and weather forecasts, with the help of which, in addition to the real-time line rating and sag-clearance analysis, a predetermined line rating could also be determined. The investigated system also included an ice prediction subsystem as well as a sag-calculation-based ice detection subsystem. Based on the comparison of the measured and calculated parameters, it can be said that both the operation of the sensors and the quality of the data provided by them were satisfactory. In the case of conductor temperature calculation, the developed mathematical models, which can be applied independently, provided information to the system operator with almost similar accuracy than sensors' measurements. During the observed period, the ice prediction and detection subsystem were also tested and functioned correctly. As an overview of the project, it can be concluded that an efficient DLR-sensor-based anti-icing system is possible to be realized on the high voltage distribution power grid. (c) 2022 The Author(s).
