High proportion of new energy sources accessing the power grid puts higher requirements on the flexible regulation capability of the power system.In this paper,an optimal dispatch model for industrial parks is proposed to provide ramping services to the superior power system.Firstly,the wind and solar uncertainties are processed to generate a typical scenario to calculate the flexible ramping demand of the system.Then,the scheduling cost and ramping benefit are considered comprehensively to construct a two-phase optimal scheduling model with the objective of minimizing the total cost of the park operation.Finally,the case study is conducted and the results show that the revenue of the park after the participation of high-capacity loads in the flexible ramping service increased by 57.01%compared with the previous one,and the park operating cost decreased by 11.5%compared with the time when the high-capacity loads don't participate,which effectively improves the flexibility of the system and reduces the operating cost of the park.
