Abstract: At the moment, the problem of wind curtailment in the Northwest is still serious. In this context, to improve the wind power accommodation of a system, this paper combines the adjustable resources on both sides of generation and load in the Northwest and proposes a day-ahead and intra-day scheduling strategy of the concentrated solar power (CSP) station with thermal energy storage (TES) and a wind farm considering coordination between generation and load. Firstly, considering the energy shifting of the CSP stations and the long response time of residential load, a day-ahead scheduling model has been constructed with price-based demand response (PDR) and the aim of minimizing the operation cost and the wind curtailment in day-ahead scale. Then, given the flexible adjustment ability of the CSP stations and the short response time of intensive energy loads, this paper has built an intra-day scheduling model for the minimal adjustment cost and the wind curtailment in intra-day scale according to the day-ahead scheduling plan and the intra-day wind power forecast. The simulation results show that the proposed strategy can promote wind power accommodation while reducing system cost by making full use of the adjustable resources on both sides of generation and load and their characteristics.

Key words: wind power accommodation, CSP station with TES, PDR, intensive energy loads, day-ahead and intra-day scheduling strategy
