“…The prime task to protect the PV system is to decide the protection level, ratings of Surge Protective Devices (SPD) and proper placement of the SPD. As per the review done in [83], protection of the PV system against lightning can be achieved by following the IEC 62305 [84][85][86][87]. The induced overvoltage developed due to lightning event hampers solidstate devices in PV inverters, which shall be prevented by using un-gapped Metal Oxide Surge Arrester (MOSA) as suggested in [88].…”

Nepal is a Himalayan country with its 83% of its geography being composed of hills and mountains. Around 22% of the Nepalese population is not receiving electricity through the national power utility and is forced to identify alternative approaches to electrification. The Micro/Mini-Grid (MG) system is one of the promising approaches in terms of cost, reliability and performance for rural electrification, where electrification through national power utility is not techno-economically feasible. However, various issues must be identified and considered during the implementation of MGs in a rural community. In this paper, numerous technical, social and management issues are identified and discussed relating to the implementation and operation of reliable and stable MGs in the Himalayas. To our knowledge, this is the first scientific work that presents a comprehensive review of Himalayan MGs and their associated elements. This article reviews the available research articles, project documents, and Government reports on MG development, from which a clear roadmap is constructed. From the comprehensive study, it is observed that the existing MGs are not adequately designed for the specific area, considering the local resources and local information. Based on the identified issues, some practical and efficient recommendations have been made, so that future MG projects will address the possible problems during the design and implementation phase.

“…Therefore, a lightning strike is the most threatening factor for the owners because it is correlated with the facility safety and output power reliability. In this case, a lightning protection system is very important for a PV system installation for the sake of fault clearance, equipment fire hazards and other dangerous effects [82]. For these requirements, it is essential to have practical guidelines and standards for PV system protection to lightning strike threats.…”

Recently, detection and identification of faults in photovoltaic (PV) system applications have been attracting researchers worldwide. Some of them have investigated the causes of potential faults, have worked on how to monitor and identify the faults through fault diagnosis, and have elaborated on how to develop problem-solving methods for the early detection of faults in PV system operations. This paper attempts to provide information comprehensively from the previous research. It summarizes types of faults, methods used in early fault identification and monitoring, and PV fault prevention and protection systems. The paper also investigates future trends in PV system fault diagnosis which include real-time implementation. The paper is expected to bring new perspective about the literature associate with fault studies in PV systems. This survey will be beneficial for the future discussion on how to provide comprehensive solutions for PV system fault problems. It will help avoid research repetition on similar topics and focus on the improvement and performance development of PV fault diagnosis methods.

“…As a matter of fact, PV power systems have many conducting wires and massive metallic parts: DC cables, internal circuitry, modules metal frame, metallic support construction, grounding systems, lightning protection system (LPS) and so on. The conductors couple with electromagnetic fields associated with lightning electromagnetic pulse (LEMP), which can release significant amounts of electromagnetic energy to the PV module yet without direct current flow [2,[4][5][6]. This may result in the dielectric breakdown of PV modules [2,7,8] or in power conditioner and measurement circuitry malfunctioning [9][10][11].…”

Nearby lightning strikes are prone to induce overvoltage transients in photovoltaic (PV) modules and in their power conditioning circuitry, which can permanently damage the PV system. Therefore, it becomes important to establish a method for accurate assessment of such transients. To this aim, the authors propose a three-dimensional (3D) semi-analytical numerical method to study the electromagnetic transients caused in PV modules by nearby lightning strikes. The approach bases on a semi-analytical expression of the magnetic vector potential generated by a geometrically complex lightning channel. The proposed method is able to calculate the transient overvoltage in a PV module, both in common and differential-mode, taking also into account capacitive and inductive couplings between the internal circuit and the PV metallic frame. Both modes are required to design the surge protective devices (SPDs) in PV power systems. Comparing to the models in literature, the proposed approach explicitly considers the complex geometry of the lightning channel. Statistical analysis allows assessing the impact of channel geometry by randomly generating a number of likely lightning paths. Results show that the lightning-induced overvoltage in a PV module is highly dependent on factors such as distance to the lightning channel and lightning channel geometry.
