The Sunshine State Solar Grid Initiative (SUNGRIN) is a High Penetration Solar Deployment Projects. The Project is focused on understanding and removing the regulatory, technical, and economic barriers to integrating high penetration of solar electricity into the electric grid. Increasing the growth of grid-tied solar photo-voltaic systems; accelerating the placement of these systems into existing and newly designed distribution circuits in the electrical grid; and supporting the mission to increase widespread commercialization of clean solar energy technologies. The idea of the SUNGRIN project is to gain significant insight into effects of high-penetration levels of solar PV systems in the power grid, through simulation-assisted research and development involving a technically varied and geographically dispersed set of real-world test cases within the Florida grid.
