    This paper presents an approach to solving the optimal load flow by decoupling the complete problem into P - subproblem and Q- subproblem. The analytic method is applied to determine, the participation factors in the constrained economic dispatch stage. The modification by the transmission losses is taken into consideration by using "relative penalty factor ψ1" and the power balance equation derived from the modified equation of the load flow.

    This paper presents an approach to solving the optimal load flow by decoupling the complete problem into P - subproblem and Q- subproblem. The analytic method is applied to determine, the participation factors in the constrained economic dispatch stage. The modification by the transmission losses is taken into consideration by using "relative penalty factor ψ1" and the power balance equation derived from the modified equation of the load flow. There is no specification of a slack bus in the formulation of the load flow. In the second stage(reactive power optimization) the reduced gradient method is used to go with the penalty function method. The numerical results for 5- bus, 11-bus and IEEE 30-bus systems are given in this paper.

    本文提出的解算优化潮流的方法,是把整个优化问题分解为有功和无功两个子问题。在受约束的有功经济调度阶段应用分析法确定有功的分配因子。线损修正是通过由潮流的修正方程式导出平衡方程式和“相对线损修正系数Ψ_i”来考虑的。在潮流的定式中采用不设置平衡节点的方法。在第二阶段(无功优化)是应用简化梯度与惩罚函数相结合的方法。文中列出了5节点、11节点和IEEE30节点的系统所进行的数值计算结果。

    This paper presents an improved DC load flow with compensation of bus voltage, and based on these improvements and decoupled Happ's formula, two economic dispatching algorithms are proposed. As they avoid double iteration and the advanced programming technique is adopted, the satifatory economic dispatching and more precise load flow calculations can be completed within the same time, and the total running time is shorter than 1/3 of that of the fast decoupled load flow only.
