Wind power operation capacity credit assessment considering energy storage

Abstract

Research on wind power capacity credit at the operational level plays an important role in power system dispatching. With the popularity of energy storage devices, it is increasingly necessary to study the impact of energy storage devices on wind power operational capacity credit. The definition of wind power operational capacity credit is given. The available capacity model of different generators and the charging and discharging model of the energy storage are established. Based on the above model, the evaluation method of wind power operation credible capacity considering energy storage devices is proposed. The influence of energy storage on the wind power operation credible capacity is obtained by case study, which is of great help for the power system dispatching operation and wind power accommodation.
