Aiming at the failure of using active power reserve in dispatching process for power system due to insufficient transmission capacity of lines, a coordinated dispatch method of active power and reserve for power systems based on extreme scenario analysis is proposed. Firstly, an optimal dispatching model considering reserve availability is introduced. Secondly, based on continuous greedy algorithm, a method of generating extreme scenarios considering the adjusted range of output for units is developed. Finally, the model is decomposed into main problem of reserve economic allocation for prediction scenario and several checking problems of reserve availability for extreme scenarios and solved iteratively. The case studies are carried out on a 10-unit and 39-node system in New England. The results show that the proposed approach not only can effectively solve the problem of reserve availability, but also identify the important lines and time periods that affect reserve availability.
