Increasing penetration of intermittent wind power generation in interconnected networks requires the integration of energy storage system (ESS) to minimise the mismatch between load and generation. Generation capacity value assessment is an essential aspect of power system planning. In this paper, a methodology has been developed for the capacity value assessment of ESS with wind power generation. The availability models of ESS during charging and discharging cycles have been developed that takes into account the unavailability of ESS during discharging periods, typically due to outage at charging periods. The proposed method has been tested on the modified IEEE RTS-79 system, which includes two wind farms. The capacity values of ESS have been estimated for the case when the ESS is used for reliability improvement and when ESS is used for reducing the variability of the output of the wind generation. An analysis of the influencing attributes on the capacity value estimation has been presented and discussed.
