Abstract
Renewable Energy Sources (RES) are emerging as a mainstream electricity generation option in many parts of the world. However, achieving the frequency stability is a major challenge when the RES penetration is high. This paper investigates the impact of large-scale deployment of Photovoltaics (PVs) on equivalent inertia constant of the power system. In addition, this study examines the minimum frequency and the rate of change of frequency resulting in high penetration of PVs. Case studies are used to demonstrate the frequency dynamics of the projected Sri Lankan power system in 2020 and 2030 considering solar penetration and demand.
