摘要：
The reserve capacity required against the forecast error and power output fluctuation due to the randomness and fluctuation of wind power is analyzed, the relationship between the reserve capacity demand and the power output of wind power is analyzed according to the probability distributions of wind forecast error and wind power fluctuation, and a reserve capacity demand model of wind power is proposed, based on which, a dispatch model with the coordinated optimization of active power and reserve capacity is established for the power grid with wind farm. The system reserve capacity demand is divided into two types: fast reserve and emergency reserve. The reserve capacities of two types can be optimally allocated among the units while the optimal power output schedule of each unit is achieved. The simulative calculations are carried out for the modified IEEE 6-bus system and IEEE 118-bus system, verifying the rationality and effectiveness of the proposed model and method. © 2016, Electric Power Automation Equipment Press.
