Guidelines for large photovoltaic system integration

The paper summarizes the result of a research project funded by the Department of Energy (DOE) in collaboration with the University of California at San Diego (UCSD), [1]. One presents a planning guideline and establishes interconnection criteria for integrating Photo Voltaic Generation (PVG) into the power systems (transmission and distribution). Some of the experiences/guidelines in the field of wind farm integration are used here since wind generation and PVG generation share many common power electronics devices used in their control schemes and both generation types are intermittent resources with similar degree of predictability and forecast methodology. Recommendations are given on the best practice promising standards for interconnecting large PV generation to power system.
