“…There are also many more wind power enhancement or wind power integrated systems' advanced operation-oriented studies for DLR supported transmission systems [57][58][59][60][61][62][63][64][65][66][67][68][69][70][71]. A DLR application in Mexican National Electric Grid considering all different subgrids of 115 kV, 230 kV, and 400 kV was considered in [57].…”

“…The mentioned study in [57] especially demonstrated the direct correlation between DLR based congestion cost alleviation potential for the OHLs close to wind power plants. The field data for applying DLR for the lines connecting wind power plants and hydroelectric plants were shared in [58,59] by Terna S.p.A as the Italian TSO. A two-stage stochastic co-optimization model for energy and reserve allocation considering DLR forecast errors in the second stage of the process was proposed in [60] and tested using a wind power integrated IEEE 24-bus sample system.…”

The need for flexibility in power system operation gradually increases regarding more renewable energy integration, load growth, etc., and the system operators already invest in this manner to enhance the power system operation. Besides, the power system has thermally sensitive assets such as lines, transformers, etc. that are normally operated under highly conservative static ratings. There is a growing trend in this regard to use the actual capacity of such assets dynamically under varying operating conditions leading to a dynamic thermal rating concept which is referred as dynamic line rating (DLR) approach specifically for lines. This study provides a comprehensive overview of existing perspectives on DLR and combination with other flexibility options from an operational point of view. Apart from the existing review studies more focused on implementation category of DLR concept, the concentration on more operational stage from the power system operation point of view leads the difference of this study compared to the mentioned studies. A categorization of the DLR implementation for either being sole or combined usage as a flexibility option is further realized. Besides, a geographically categorized analysis on existing practical evidence on DLR concept and implementations is also presented in this study.

“…Wide‐area implementation of DLR systems can be realized relatively quickly with weather‐based indirect approaches, due to comparatively short installation times and low capital costs, compared with direct approaches (Kosmač et al, 2020; Phillips, 2013). These systems can also be combined with direct measurements in a mixed approach, in order to improve system accuracy in parallel to capital cost mitigations (Massaro et al, 2019).…”

Dynamic line rating (DLR) systems are recognized as a cost-effective and socially accepted asset for relieving network congestion and uprating existing transmission systems, based upon accessing additional weather-dependent capacity of overhead lines. Although direct and indirect DLR methods are available, utilization of indirect weather-based approaches, that is, sensors are not installed on the conductor, are of increasing interest due to fast installation times, that is, no requirement for line outages and lower capital costs, with achievable potential for wide-area implementation. An extensive review is presented on the components and requirements of such systems, including weather stations, forecasting models, downscaling and DLR calculations, overhead line and conductor thermal models, and communication platforms. In addition, the features of practical instances of these systems are briefly reviewed. Moreover, a systematic approach is introduced for statistical evaluation of the high-level DLR potential across an entire region, as well as an assessment of the line-level DLR ampacities within an electrical grid, based on (weather forecasting) reanalysis data. The proposed methodology can disclose available additional capacity as part of early-stage planning for wide-area DLR systems. The island of Ireland and the 110 kV network of the Republic of Ireland (ROI) power system are considered as the study cases, with comparison made against seasonal static ratings and ambient temperature adjusted line rating methods.

“…Many investigations have been conducted on the impact of DTR on power networks. Among them, many studies are focusing on the DTR impact on the penetration of RESs, especially wind turbines/farms [10][11][12][13][14][15][16]. In [10], it has been shown that DTR consideration has positive effects on the penetration level of wind turbines.…”

“…Additionally, there is another group of researches focusing on DTR effects on transmission line congestion and constraints. In [12], it has been shown that using DTR can reduce the curtailments of RESs which is an important economic saving for the system and also a remarkable environmental benefit. In [13], it has been revealed that DTR implementation can help to reduce the congestion costs and LS risk.…”

In this study, new technologies such as dynamic thermal rating (DTR) technology and energy storage system (ESS) are simultaneously used to optimise the integration of renewable energy sources (RESs) and minimise the load shedding. For achieving the mentioned aims, a new method is proposed to select the candidate lines for the implementation of DTR technologies. The DTR technology is responsible for increasing lines limited capacity. Moreover, optimally placed and sized ESSs save RESs generated power in non‐peak‐hours and inject it to the network in peak hours. For validating the performance of the proposed solution, comprehensive simulations are performed in several stages on IEEE RTS‐24‐ and 30‐bus test systems networks. To meet the increased power demand, RESs (wind and solar) are optimally allocated by using the genetic algorithm (GA) in the test systems. Then, ESS devices are optimally sized and placed by using GA. Finally, candidate lines are selected based on the proposed method and DTR devices are added to the systems. Comprehensive comparisons are presented for comparing the previously presented solutions and the proposed one. It is proved that using DTR technology and ESSs along with the proposed line selection method is the superior solution for system operators.
