The modern power markets introduce higher penetration levels of solar photovoltaic (PV) power generation units on a wide scale. Along with their environmental and economic advantages, these variable generation units exhibit significant challenges in network operations.
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.
Challenges hindering energy storage system adoption As the demand for cleaner, renewable energy grows in response to environmental concerns and increasing energy requirements, the integration of intermittent renewable sources necessitates energy storage systems (ESS) for effective utilization.
Solar and wind energy have become much cheaper to generate but have a major disadvantage of being intermittent and hence require reliable means and methods of storage. This intermittency means that the storage systems have to not only be effective in their ability to store the energy but also cost-effective in the long run; a big issue.
Concerning power systems, the high penetration level of PV can cause temporary stability difficulties, especially in transmission systems. Effective procurement and analytical procedures are used to overcome the system's steady-state and transient-state performances (Emmanuel et al. 2012).
