Abstract: In order to inhibit the wind power fluctuation and reduce wind curtailment, a new wind-CSP hybrid power generation system was proposed in this paper in consideration of that concentrated solar power（CSP） with thermal energy storage（TES） was dispatchable. This new hybrid system consists of a wind farm, a CSP with TES, and an electric heater（EH）. The EH plays the role of converting the redundant wind power into thermal energy, which is then stored by the TES, and can be converted to power energy by CSP when it is needed. This is beneficial for both reducing the wind curtailment and improving the flexibility of the system. A mixed-integer linear programming（MILP） model is established to minimize the gap between the system’s output and the planned load and to maximize the efficiency of energy utilization. Contrastive studies are conducted by test cases in a clear sky and partial cloudy day respectively, in which a wind-CSP hybrid system without EH is taken as the reference system. The test results show that the system proposed in this paper can follow the planned load better, reduce the wind curtailment effectively, afford more heat energy to CSP and provide the system with more flexibility and schedulability.
