“…Effective capacitor placement, which aids in loss reduction, is highlighted in various papers such as [36], [50], [88]. Some studies have also focused on cost minimization for transmission lines, illustrated in [93], and enhancing reliability by reducing losses, as seen in [146]. Additional research on minimizing energy loss costs can be found in [75] and [77].…”

Conductor size selection (CSS) is critical for the optimal design and operation of distribution networks. CSS, like other aspects of network planning, has become increasingly sophisticated as the prevalence of distributed energy resources (DERs) increases. This complexity is linked to DER operational and planning uncertainties, which often exacerbate network issues. Increased uncertainty and uncontrolled DER penetration can result in increased conductor loading and extreme voltage performance concerns (rise, drop, and unbalance) that lower the quality of supply (QoS). Traditional CSS techniques, which were developed for passive systems, do not take DERs into account. Therefore, continued application of these methodologies in CSS for modern networks is untenable. As a result, the shift towards active network design and planning requires new CSS techniques that can enhance the adoption of DERs and facilitate optimal longterm network planning. This paper presents a review of CSS methodologies, focusing on the advances made to accommodate DERs, particularly the adaptation of modeling processes to cater to DER planning and operational uncertainties, and its impacts on other key aspects of CSS. Key CSS processes, including the choice of the CSS objectives, input (loads, generation, and feeder) modeling, load flow assessment, optimization, as well as the incorporation of risk in DER analysis are discussed. Informed by the review, the paper scopes the requirements for a robust CSS methodology for active networks with high DER penetration. The findings of the paper are relevant to future research in the field of active distribution network design with a focus on optimizing the integration and utilization of DERs and the related technical performance of networks.

“…Studies devoted to the optimization problem of minimizing the capital costs of a TL with respect to the selection of the optimum cross-sectional area of the conductor applied deterministic [15,16] and stochastic methods. For instance, the proposed stochastic approach to selecting the conductor cross-section, which takes into account random variables such as the power line load, electricity price, and ambient temperature, was presented in References [17][18][19]; the method of selecting the conductor and tower configuration from an overall system point of view was considered in Reference [20]; and the methodology for selecting both bare wire conductors and ground wires, their spatial arrangement, and the topology of the tower for a project with compact overhead transmission lines with multiple circuits was presented in Reference [21].…”

Transmission networks recently faced new technical and economic challenges. The direct use of advanced technologies and modern methods could solve these issues. This paper discusses the potential application of straightforward technology such as high-temperature low-sag conductors (HTLScs) as an additional measure for the protection and effective operation of overhead power lines. An evaluation was conducted to determine an approach for selecting the cross-sectional area and type of conductor with respect to a fault current limitation. It showed the potential benefits of using HTLScs based on an assessment of the throughput capacity and up-front capital costs. A case study considered two scenarios: the construction of a new power line and reconductoring of the existing one. The data for a real project with two overhead power lines were used. The obtained results are analyzed and discussed in detail in this paper.

“…It means that there are no unique exact optimization techniques. Thus, there are two basic categories: deterministic (classical) methods and stochastic methods [1], [18]- [20]. The existing deterministic approaches are simpler, however, they make several assumptions that neglect the fluctuations of the energy prices and are based on the deterministic statements and a rough approximation of the electrical loads.…”

This paper deals with the concept of the stochastic optimization methodology for power line designing, which allows optimizing transmission network planning. The paper presents a comparison of both methods applied for selecting the best line design alternative -the deterministic economic intervals method and the stochastic approach based method, taking into account market conditions. Both methods are utilized for designing overhead power lines, including the choice of main line parameters such as tower height, type and coordinates, conductor type and cross-section, line fittings, etc. Moreover, the use of High Temperature Low Sag conductors -a part of the advanced technology -was evaluated alongside the use of conductors of the traditional type. The optimization problem is formulated as minimization of the total annual costs. The proposed methodology is tested in the developed tool, which is realized in MATLAB software by using the Monte Carlo method, and in an overhead power line designing program -PLS-CADD. Two basic case studies for verifying the proposed power line planning solution are presented in the paper.
