Off-grid solar PV system is independent of the grid and provides freedom from power quality issues and electricity billing. The excess energy can be accumulated in the battery storage units through superior control. The main research challenges in off-grid are to provide support to load when sudden changes happened in a closed network of the load.
Power fluctuation is the nature phenomena in the solar PV based energy generation system. 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.
This characteristic promotes the safety of a grid-connected PV system by preventing continuous power delivery to the grid during downtime. Fig. 3. On-grid PV system B. PV SYSTEMS PERFORMANCE Using a battery storage system along with the PV generating station also helps stabilise the solar PV's fluctuating output.
The main block diagram of the solar photovoltaic system integrated with the micro grid is shown in Fig. 1. modes of operation. The stand-alone systems are bene ficial in remote areas that are isolated from the power distribution network. For remote areas where the AC mains behaving as an AC voltage source.
The main component in grid-connected PV system is the inverter. It converts available DC quality requirements of the grid utility. A bidirectional interface is made between the PV system AC output terminals and the grid utility network. This enables PV system load demand power. At night or during high load demands, the power requi red by load
Off-grid energy systems are the systems that are disjoint from the power distribution grids and have their own generation and storage mechanisms. The energy generation techniques through renewable sources for remote and isolated areas in an off-grid scheme are reviewed.
