Renewable Energy Capacity Value Estimation Using Peak Period Method in Rajasthan

Abstract

This paper deals with calculation of capacity value of renewable energy (solar and wind energy) in Rajasthan. Capacity value refers to the contribution of a power plant to reliably meet peak power demand. This implies that if a 150 MW solar plant has a capacity value of 50%, it can contribute 75 MW of power to reliably meet demand, and thus reduce the strain on conventional power generation plants. The capacity value calculations involve the comparison of hourly capacity factor of the grid connected renewable energy plants in the state, with the state's hourly demand met, and hence provide an understanding of the contribution of renewable energy towards meeting system reliability. In this paper, the capacity value has been calculated for different districts in Rajasthan with respect to the state's hourly demand data. Four districts are considered for wind energy estimation and five districts are considered for solar energy estimation. The results of all districts considered in this analysis have been combined and showcased at the state level. Capacity value calculations have been done for solar system, wind system, as well as a combined solar and wind system at the state level.
