Abstract: A mathematical model is established based on the analyses of energy storage technologies and the structural traits of a power grid for accommodating intermittent renewable resources, subject to constraints of the maximum amount of power the grid can release for the renewable generation and the reduction of wind wind/PV curtailments. The analyses consider energy storage system investment and return due to the increase of renewable energy related income. Two provincial power grids (which mainly accommodates wind and PV generation) are used as examples for the validation of analyses.

Key words: renewable energy resource, accommodation, energy storage, wind power curtailment, PV curtailment
