Significant issues such as high-Power Loss (PLoss) and drop in node voltages in Electric Distribution Networks (EDNs) can be well mitigated using renowned techniques such as Alteration of Electric Distribution Network Switches (AEDNS), Optimal Capacitor Support (OCS), and Integration of Dispersed Generation (IDG), which are identified as the most economical and efficient approaches. This study presents the optimisation of AEDNS with and without OCS considering four different scenarios to maximise the profit through reduction in PLoss, which is regarded as the first-step process. To further increase profit, IDG was integrated into the EDNs after the combined optimisation of OCS and AEDNS. In this work, Levy Flight Mechanism (LFM) was incorporated into the Seagull Optimisation Algorithm (SOA) and applied to solve the objective function based on economics. The effectiveness of the presented methodology was evaluated and confirmed using a real 59-bus in Cairo, Egypt, EDN, as well as a conventional 33-bus test system. For each scenario, the PLoss reductions and net profit of the proposed methodology were contrasted with those obtained from previously reported approaches. The collected findings show that by optimising AEDNS, OCS, and IDG, the established methodology effectively yields more economic gain for all scenarios.

“…Since a significant portion of solar radiation is converted into heat energy upon reaching the surface of the solar cell, the operating temperature of the solar cell often exceeds 50 • C and can even reach as high as 80 • C [57,58]; therefore, it is imperative to investigate the heat dissipation mechanisms of solar cells within pavement PV systems. To address the heat dissipation challenge of solar cells, the integration of PV technology with thermal technology offers an effective solution, namely, the PV/thermal (PV/T) system [59,60]. Although the research on solar PV thermal building-integrated systems (BIPVTs) is more extensive [61][62][63], there is a relative scarcity of studies exploring the application of PV/T systems in pavement contexts.…”

Pavement photovoltaic (PV) is an innovative energy-harvesting technology that seamlessly integrates into road surfaces, merging established PV power generation methods with conventional roadway infrastructure. This fusion optimally utilizes the extensive spatial assets inherent in road networks. This paper offers an exhaustive examination of the literature concerning the physical models and performance evaluation of photovoltaic pavements. This study delineates the essential three-tier structure of pavement modules and juxtaposes the advantages and drawbacks of design models across these strata, thereby facilitating the development of more suitable solutions for varying application scenarios. The importance of accommodating fluctuations in shadows and countering the heat island effect (HIE) is emphasized. Nevertheless, the technology remains in its nascent research phase, characterized by challenges associated with limited long-term durability and efficacy. Building upon these findings, this study addresses the challenges confronting pavement PV from three perspectives and outlines future prospects and recommendations for its progression.

Zero insulators directly reduce the electrical performance of insulator strings, affecting the safe and reliable operation of transmission lines. The grounding current of the insulator string contains the characteristic information of insulator electrical performance. Extracting the characteristic information of grounding current can realize the detection of zero value insulator, which is of great signi cance to ensure the safe operation of transmission lines. In this paper, the composite insulator used on ultra high voltage (UHV) lines is studied to analyze the in uence of zero insulators on the electric eld distribution.Furthermore, the corresponding characteristics of the zero insulators at different locations are extracted. The tting relationship between the characteristic quantity and the zero-insulator position is analyzed.The effective characteristics of grounding current are selected as training sample to establish the zeroinsulator position prediction model based on probabilistic neural network (PNN). The research result is meaningful for the detection of zero insulators.
