摘要
本文证明了最优潮流与经典经济调度的相通性,即:当所有不等式约束都不越界时,最优潮流遵循有功方面的等耗量微增率原则和无功方面的等网损微增率原则;当电源功率违界时,违界的电源退出协调区,留在协调区内的电源仍然服从等微增率原则;最优潮流中的拉格朗日乘子也满足相应的等微增率关系。
In this paper, the relationship between optimal power flow and classical economic dispatch is demonstrated. Under the condition that the nonequality boundaries are not.violated, the real power optimization of optimal power flow satisfies equal consumption(or cost) increment principle, and the reactive power optimization satisiies equal network loss increment principle. When the power of some generators exceeds its limits, the equal increment principle is satisfied by the other generators. The Lagrangian multipliers in optimal power flow also satisfy the corresponding equal increment principle.
