考虑最优潮流约束的机组组合并行解法

针对传统机组组合模型的不足,提出一种考虑最优潮流约束的机组组合模型并给出了其并行化解法.该法借助于扩展拉格朗日和变量复制技术,将原问题转换为其对偶问题,并利用附加问题原理将对偶问题分解为动态规划和最优潮流子问题.对于最优潮流子问题,采用预测校正内点法求解,同时在求解过程中,采用并行处理技术.IEEE118节点及IEEE300节点仿真结果表明,该方法性能稳定,收敛性好,并行处理后计算速度显著提高.
A Parallel Unit Commitment Algorithm Including Optimal Power Flow Constraints
This paper proposes a new parallel algorithm for unit commitment including optimal power flow constraints.The algorithm employs a new Augmented Lagrangian method that involves the Variable Duplication technique.By using the Auxiliary Problem Principle,we can convert the primal problem to its dual problem and get the separate structure of the Augmented Lagrangian which allows its implementation in parallel computers.With preliminary implementations of the algorithm,we have been able to solve the IEEE118 and IEEE300 problems reliably.Meanwhile the calculation speed is increased sufficiently by using parallel computation.
