I. Introduction
Because of its desirable environmental characteristics and compatibility with distributed applications, photovoltaic (PV) electric power generation is particularly favored from a public policy standpoint. This, combined with decreasing prices for PV equipment, will lead to a dramatic expansion of PV generation. As PV reaches significant grid penetration, both on a local level as well as on a regional level, it will become increasingly important to mitigate the potentially adverse local impacts caused by variability of PV generators, and it will also be necessary to ensure the continuity of these resources during grid events where loss of generation resources can be particularly detrimental to the regional power grid.
