Stochastic unit commitment for wind power interconnected system reserve requirement estimation

Due to the nature of intermittency and prediction uncertainty, wind energy impacts power system operation across different time frames. Among these operational impacts, increased reserve is a need to compensate for wind power uncertainty. To estimate reserve requirement against wind power uncertaint...

Summary:Due to the nature of intermittency and prediction uncertainty, wind energy impacts power system operation across different time frames. Among these operational impacts, increased reserve is a need to compensate for wind power uncertainty. To estimate reserve requirement against wind power uncertainty, in this paper, a stochastic unit commitment approach is presented. The effects of reserve price on reserve requirement are investigated. A numerical case study demonstrated that the proposed approach is effective to estimate reserve requirement. The benefits on cost saving and reliability improving of stochastic unit commitment are verified by the case.
