  惩罚项
     Many different penalty terms have been discussed in the literature [1-3, 6, 10-13], and most of the studies are based on the experiments.
     已有许多文献研究了多种不同形式的惩罚项[1-3,6,10-13],但他们中的大多数是在实验的基础上对惩罚项的性能进行研究的,并没有在数学上给出理论证明。 本文从理论上分析了惩罚项对权值的压制作用,从而为以上实验观察结果提供了理论依据。

  penalty terms
Performance can be improved by representing the system with an objective function whose minimum is associated with a good configuration; the various constraints appear as penalty terms in the function.
      
Penalty terms are introduced in the cost function to account for constraints imposed on points that result from sampling the sets to which the trajectories of the state and of the estimation error belong.
      
A preconditioner is constructed with the property that the rigid constraints are satisfied while ill-conditioning due to penalty terms is alleviated.
      
Close approximations to solutions near the constraint boundaries are found by applying Carroll's approach in successively reducing the weighting factors of the penalty terms.
      
To render this approach feasible in the presence of constraints, the functional is modified to include penalty terms which cause the functional to approach infinity at the constraint boundaries.

The formulation and proof of a quadratic equivalence principle are presented in this paper. The principle states that a non-degenerate linear programming problem is equivalent to a separable quadratic one obtained by adding a special penalty terms to the original problem. Based on this principle, a point convexifying technique is introduced, which can be used to convexify linear programming or linear steady state control problems so that the interaction balance method can be applied. A simple example is...

It maintains the advantages possessed by the linear programming model, that is, rapid calculation, reliable conver-gency and easy treatment of N and N-1 line-security constraints- At the same time, it settles quite exactly the problem of non-linear cost characteristic by incorporating the differential loss coefficients into the objective function.

A successive linear programming model with penalty terms for solving real-time secure economic power dispatch is presented in this paper. It maintains the advantages possessed by the linear programming model, that is, rapid calculation, reliable conver-gency and easy treatment of N and N-1 line-security constraints- At the same time, it settles quite exactly the problem of non-linear cost characteristic by incorporating the differential loss coefficients into the objective function. Introducing the fictitious generation variables into the model not only guarantees the solvability of the successive linearization from beginning to end, but also enables us to find out the locations and the values of optimal loadshedding if there have to be some load-sheddings to obtain N and N-i security. The calculation results of the IEEE 30-bus system indicates that the proposed model has the same accuracy as the non-linear models while it needs much less computing time.

本文提出了一个逐次的带有惩罚项的线性规划模型来求解N及N—1安全性实时经济调度问题。该模型保持了线性规划模型的优点,又相当精确地解决了非线性费用目标的问题。在模型中引入虚拟发电量不但使逐次线性化过程始终有解,而且当必须甩负荷才能满足N及N-1安全性约束时,可给出最优甩负荷的节点及其量值。对IEEE30节点系统的计算结果还表明,本模型与非线性模型相比,具有相同的优化精度,但所需计算时间却少得多。
