Renewable Energy World discusses the nuts and bolts of getting solar power operational at utility-scale.
Dispatchability — The ability to be able to turn solar services on and off at a moment’s notice.
Stability — The ability to manage the fluctuation of grid currents caused by the introduction of solar systems.
Manageability — The ability to effectively manage the different aspects of traditional and renewable energies as they coexist throughout the grid
They have lots of detail on each point.
