Power quality is an essential factor for the reliability of on-grid PV systems and should not be overlooked. This article underlines the power quality concerns, the causes for harmonics from PV, and their mitigation strategies considering the scope of research on the effect of voltage/current harmonics from PV-inverters on the grid.
When solar systems are attached to the grid, we may see power quality problems occur for both the solar site and the utility. The output of a solar panel is always fluctuating. This output goes through an inverter in order to convert the DC to AC. An unconditioned AC voltage can create various power quality issues.
To maintain the power quality in grid-connected solar PV systems, some power quality standards are designed, and monitoring of power quality helps to detect the different PQ issues in the system. These PQ standards, monitoring, and issues are mentioned in the following subsections. 2.1. Power quality standards
In terms of continuous supply, power quality refers to a collection of indications that reflect the characteristics of the sources of supply under typical operational circumstances of voltage and frequency.
When solar PV sources are integrated to the AC grid to enhance reliability, pose PQ challenges due to the intermittency nature of the solar and the low strength of the rural grid , , , , , , , , , , , .
The output of solar PV is highly intermittent due to its dependency on irradiance, temperature, and atmospheric conditions. This enhances PQ disturbances when integrated with a grid which needs to be mitigated to ensure stability and smooth synchronization. These PQ challenges are likely to get multiplied in the enhancement of penetration level.
