“…Liu et al proposed a substation area protection relay, which can reduce the overall coordination degree, in an effort to address the inherent flaws of the conventional backup protection system [ 2 ]. In smart substations, Zheng et al was the first to propose a high-reliability optical process level network scheme with all-optical passive edge nodes [ 3 ]. The communication network in substations has recently received increased attention from all parties due to the emergence of smart substations.…”

Smart grids, which possess flexibility, cleanliness, safety, economy, and friendliness, have drawn a lot of attention from all over the world in an era of rapid social and economic development, power technology change, and energy and environmental constraints. However, there are still issues with the design, installation, and operation of smart substations, such as insufficient LAN integration, difficulty quantifying network performance, and inability to keep track of communication. The basic meaning and key technologies of substation communication standards are used as the research object in this paper, and the basic attributes of substation data flow, such as source, type, and function, are qualitatively analyzed. The mathematical model that is most closely fitted is 2.8% more effective. The research object is the topology of the process bus. Through the comparison of various solutions, including star topology, ring topology, bus topology, and mesh topology, the advantages and disadvantages of each topology networking scheme are revealed along with the particular functional requirements of the substation process layer. Further discussion is given to the crucial topology-related technologies of network congestion and flow control.

“…Colmenar-Santos et al (2016) used second-generation superconducting to implement an advanced fault current limiting device. Zheng et al (2020) reported that an optical process-level network is more reliable than an Ethernet switch in doubling the interval between two successive failures of a smart substation. Enhanced protection of substations against lightning is influenced by lightning behavior and the austerity of lightning protection design for the safety of substations and power grids (Taha et al , 2020).…”

Purpose This study aims to provide a scientific framework for the selection of suitable substation technology in an electrical power distribution network. Design/methodology/approach The present paper focuses on adopting an integrated multi-criteria decision-making approach using the Delphi method, analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS). The AHP is used to ascertain the criteria weights, and the TOPSIS is used for choosing the most fitting technology among choices of air-insulated substation, gas-insulated substation (GIS) and hybrid substation, to guarantee educated and supported choice. Findings The results reveal that the GIS is the most preferred technology by area experts, considering all the criteria and their relative preferences. Practical implications The current research has implications for public and private organizations responsible for the management of electricity in India, particularly the distribution system as the choice of substations is an essential component that has a strong impact on the smooth functioning and performance of the energy distribution in the country. The implementation of the chosen technology not only reduces economic losses but also contributes to the reduction of power outages, minimization of energy losses and improvement of the reliability, security, stability and quality of supply of the electrical networks. Social implications The study explores the impact of substation technology installation in terms of its economic and environmental challenges. It emphasizes the need for proper installation checks to avoid long-term environmental hazards. Further, it reports that the economic benefits should not come at the cost of ecological degradation. Originality/value The present study is the first to provide a decision support framework for the selection of substation technologies using the hybrid AHP-TOPSIS approach. It also provides a cost–benefit analysis with short-term and long-term horizons. It further pinpoints the environmental issues with the installation of substation technology.
