Large-scale PV system is being installed in transmission and sub-transmission network around the world in large numbers with higher capacities. It is anticipated that this trend will continue with the ‎‎advancement of power electronic devices and the lower cost of such devices. Consequently, ‎‎the power systems have undergone fundamental characteristics changes due to the high ‎‎penetration of these inverter-based generators caused by distinct dynamic characteristics of these ‎‎generating sources and inverters. Therefore, there are still some ‎‎issues with the PV ‎technology need to be ‎‎investigated. It is always good to look for the optimal way of configuration and ‎integration of ‎‎the PV system in order to utilize that expensive and low capacity factor assets effectively‎. ‎Additionally, with an ‎‎appropriate ‎‎configuration, the grid integrity will be enhanced when ‎suitable control ‎methods ‎are ‎implemented.  Hence, this Research work has two major tasks. The first one is to investigate the ‎‎influences ‎of system ‎‎‎configuration on the overall system efficiency and stability. Then, it is ‎also ‎equally ‎important to ‎‎‎develop a control strategy that coordinates all the PV system ‎elements in such ‎‎means that the grid ‎‎‎security and stability are not compromised. This research ‎work is expected ‎to contribute in a better understanding of the influence of the ‎‎‎Large-scale PV ‎power ‎plants ‎configuration and control on the grid performance and stability.‎


Saeed Alzahrani received his B.Sc.Eng from King Fahd University of Petroleum and ‎Minerals (KFUPM), Saudi Arabia in 2009. After that, he worked for two years as a ‎maintenance engineer for the Saline Water Conversion Corporation (SWCC), Saudi Arabia. ‎From 2011-2016 he was with Energy Research Institute at King Abdul-Aziz City for Science ‎and Technology (KACST), Riyadh, Saudi Arabia as a researcher.  From 2016 worked as a ‎Lecturer at Al-Baha University, Saudi Arabia. In 2015 he graduated From the University of ‎Queensland with Master of Engineering Science (MEngSc). During his master study, he ‎investigated the impact of large-scale PV on power system stability, and his thesis was titled ‎as "Large–Scale PV Impacts on Voltage: Steady State to Instability Concerns ". He is ‎currently pursuing the Ph.D. degree with the Power and Energy Systems Research Group, ‎School of Information Technology and Electrical Engineering, University of Queensland, ‎Australia. Saeed main research interests are renewable energy integration, and power system ‎stability studies.‎
