Summary:Based on the wind power development plan of Guangdong, wind power accommodation capacity of Guangdong power grid is calculated with peak regulation constraints. The sensitivity and adjustability of four parameters that affect wind power accommodation capacity were compared. Taking the minimum life cycle annual cost as objective function, the problem of energy storage system configuration is solved by enumeration method. The results show that: there will be a surplus of wind power during valley load period with peak regulation constraints in 2030, and the difference from actual installed capacity is 17.29 GW; the minimum output coefficient is the best adjustment parameter among the four parameters; according to the comparison of seven schemes; the fifth scheme has the best economic performance with the life cycle annual cost of 13.53 billion yuan and the efficiency of 63.62%. The power ratio of compressed-air energy storage (CAES), battery storage (BS) and super capacitor energy storage (SCES) is 85.40%, 8.63%, 5.97%, and the capacity ratio is 98.39%, 1.61%, 3.8e-6%, respectively.
