Constraints of Solar Photovoltaic Power Generation

What are the risks of integrating a PV system?

In conventional fossil-based systems, the major risk is fossil generator breakdown, but the integration of PV systems introduces new parameters into the reliability assessment: Risk of equipment failure in the PV power plant (PV strings, inverters) Loss of transmission system (lines and converters) between the main bus and the PV plant.

What are the problems faced by small scale solar photovoltaic energy systems?

This paper outlines the most common issues and challenges encountered during the grid integration of small scale solar photovoltaic energy systems. The major problems and suitable solutions have been also highlighted in this paper. These include the primary technical and power quality issues and the secondary economic and research related issues.

What factors affect the performance of a solar PV system?

iv. It is worth mentioning that the optimization of the PV system is closely related to meteorological variables such as solar irradiation, temperature, and wind speed. The most influential parameter that could affect the electrical properties of solar cells, as well as PV cell’s output power, is the temperature.

What are the challenges of solar PV optimization?

As a second contribution, the review has discussed the key challenges of solar PV optimization highlighting complex computation, objective function problems and algorithm integration. Besides, the study has explained the challenges relating to cost, sizing, design, placement, power quality and energy loss.

How does solar photovoltaic system integration affect distribution transformer insulation?

The severe load effects caused by the integration of solar photovoltaic (PV) systems also make it difficult to address the issue of the dependability of distribution transformer insulation. The increasing percentage of PV units installed at distribution levels increases the voltage on local feeders.

What are the disadvantages of solar panels?

The disadvantages of PV cells are the halt of electricity production at the absence of solar radiation shining on to the panel and relatively low efficiency (Jaloliddinova and Sultonov, 2019). This could lead to a lack of matching the initial investments to make the system profitable.
