The majority of the PV systems is connected to the grid and are known as grid-connected Photovoltaic (PV) system . Since the installation of the grid-connected PV system is increasing at a rapid rate, therefore, it's important to maintain power grid quality, reliability, operability, stability, and security.
The issue of modeling of PV arrays under electrical faults has been largely investigated in the literature and gets some certain results. A survey of state-of-the-art of ground, line-to-line, and arc fault detection is presented in . In Chao et al. developed a circuit-based simulation model of a photovoltaic panel using the PSIM software.
Three factors mainly involve in the disconnection of PV inverter when a fault occurs: 1) loss of grid voltage synchronization, 2) enormous AC current, and 3) excessive DC-link voltage. To fulfill the FRT standard requirements and keep the PV system connected to the grid, when a fault occurs two key problems should be addressed by the PV system.
Conclusion The on-grid PV central inverter plays a significant role in the Mega-scale PV power plant. It is the transaction equipment that transfers the generated DC power by the PV strings to the AC power to be injected into the utility grid.
In , The authors discussed several faults for the grid-tie PV system compartments. For the inverter part, both open circuit and short circuit fault are identified and localized using several symptoms such as voltage (VSA), current (CSA), and both negative and positive phase components.
For off-grid solar systems, batteries play a vital role in storing electricity generated by the panels. Unfortunately, these batteries can encounter several issues, including sulfation, overcharging, and undercharging. If neglected, these problems can result in power loss or even fire hazards.
Solar photovoltaic (PV) technology has the versatility and flexibility for developing off-grid electricity system for different regions, especially in remote rural areas.
When solar PV system operates in off-grid to meet remote load demand alternate energy sources can be identified, such as hybrid grid-tied or battery storage system for stable power supply.
