提出了一种考虑风电间歇性和波动性的安全约束机组组合算法。UC问题在预测间歇风力发电的主问题中得到了解决。接下来，模拟了风电波动性可能出现的情景。子问题中考虑了初始调度，并考虑了满足模拟情景下风电小时波动性的发电再调度。如果重新派单不能减少违规行为，则会创建折弯切割并将其添加到主问题中，以修订承诺解决方案。承诺问题和可行性校验子问题之间的迭代过程将继续，直到可以通过重新调度来适应模拟的风电情景。数值仿真结果表明，在考虑风电的间歇性和波动性的情况下，SCUC算法能够有效地管理电力系统的安全运行。
This paper presents a security-constrained unit commitment (SCUC) algorithm which takes into account the intermittency and volatility of wind power generation. The UC problem is solved in the master problem with the forecasted intermittent wind power generation. Next, possible scenarios are simulated for representing the wind power volatility. The initial dispatch is checked in the subproblem and generation redispatch is considered for satisfying the hourly volatility of wind power in simulated scenarios. If the redispatch fails to mitigate violations, Benders cuts are created and added to the master problem to revise the commitment solution. The iterative process between the commitment problem and the feasibility check subproblem will continue until simulated wind power scenarios can be accommodated by redispatch. Numerical simulations indicate the effectiveness of the proposed SCUC algorithm for managing the security of power system operation by taking into account the intermittency and volatility of wind power generation.
