Among all RET resources, solar photovoltaic (PV) systems are the most widely used off-grid solutions in remote and rural regions . This is due to the presence of abundant solar irradiance in most parts of the world and the decreasing cost of PV systems and accessories.
It is also demonstrated in IEA-PVPS Report T9-13:2013 that PV hybrid systems are technically and economically feasible as a standalone off-grid power supply system for remote and rural communities worldwide .
Therefore, off-grid solutions are considered an integral part of the standalone off-grid power supply (SOPS) systems in the remote and rural areas by energy planners. Diesel-powered systems are primarily chosen to electrify these areas due to low capital cost and consolidated supply chain in the regions .
A study conducted by Lombardi et al. (2016) proposed a framework to be used for planning new isolated power systems or upgrading the old ones in remote Russian regions. The framework was based on the AHP, aided with microgrid energy flow simulation using HOMER Energy tool.
Battery management systems (BMSs) are discussed in depth, as are their applications in EVs and renewable energy storage systems. This review covered topics ranging from voltage and current monitoring to the estimation of charge and discharge, protection, equalization of cells, thermal management, and actuation of stored battery data.
Battery Balancing: Battery balancing is an important function in a BMS for battery packs made up of multiple cells linked in series, which are popular in electric vehicles and energy storage systems.
It regulates and tracks factors such as voltage, current, and temperature in each cell of a battery pack to guarantee safe operation within set limits while maximizing battery life and ensuring the highest level of performance. In numerous ways, power electronics play an important role in battery management systems:
One way to figure out the battery management system's monitoring parameters like state of charge (SoC), state of health (SoH), remaining useful life (RUL), state of function (SoF), state of performance (SoP), state of energy (SoE), state of safety (SoS), and state of temperature (SoT) as shown in Fig. 11 .

On June 10, 2021, the 29th meeting of the Standing Committee of the 13th National People's Congress passed the Hainan Free Trade Port Law of the People's Republic of China, which determined to establish and improve the Hainan Free Trade Port customs supervision special zone system with closed-off customs operations on the entire island.
In April 2018, China announced plans to transform the island into a pilot free trade zone, with a long-term vision of developing a free trade port with Chinese characteristics. A master plan released in 2020 aimed to make Hainan a globally influential hub for high-level openness by mid-century.
Wang Yang publishes an official definition of a free port in the People’s Daily. Announcement of a free trade zone covering the entire island of Hainan during the 30th anniversary of the Special Economic Zone. Launch of the Master Plan for the construction of the Hainan Free Port, aiming for global status by 2050.
With a zero-tariff system fundamentally in place after the independent customs operation, high-quality global resources can flow into Hainan with greater freedom and efficiency, Wu said. Trade liberalization and facilitation are defining features of a free trade port.
