IEEE Transactions on Sustainable Energy, 4(3), 680–688. https://doi.org/10.1109/tste.2012.2235151This paper presents a comparative investigation of (PV) effect on system stability at different penetration levels. Three different scenarios with their relevant dynamic models are considered, namely, distributed units, and centralized farms with and without voltage regulation capabilities. Based on these models, the impact is examined through eigenvalue, voltage stability and transient stability analyses using real network data pertaining to Ontario and its neighboring systems. This impact is quantized in monetary terms based on the long run marginal cost of electricity production in Ontario. It is demonstrated that distributed solar PV generators are significantly more advantageous, from the stability point of view, than solar farms.ensolar photovoltaic generationstability studieseconomic impactArticle10.1109/tste.2012.2235151
