Power grids for high penetration of solar photovoltaic power plants- a review

This paper presents a review of power grids which have high component (~ 80 %) of solar photovoltaic (SPV) plants. It can be concluded that variability or infirmness of SPV is controllable to a large extent through detailed probabilistic modeling of the variation patterns. The immediate, short term and long term variation of SPV power plants has been discussed in depth. In a grid composed of a large number of 1-50 MW plants, the dispatchable power can be scheduled to as high as 80 % of the declared capacity in that time slot (since SPV varies in every time slot).
