Alternative Title
Optimum Control of Voltage and Reactive Power in Power System
Abstract

한편 感度行列을 基礎로 定式化된 最適制御問題를 풀이함에 있어서 損失方程式이 恒常 正의 값을 가지며 또한 凹函數이므로, 그의 極値는 最小갑이 되겠으나, 電壓 및 調整設備의 制限條件을 滿足시기는 것이여야 함으로, 本 論文에서는 가장 簡單하고 收束이 빠른 gradient法을 利用하여 反復計算으로 解를 얻었다.

As the development of large integrated power system led to the transmission of large blocks of power over longer distance, it has become necessary to pay attention not only to the voltage control problem but to a rational system operation scheme which also minimizes trasmission losses.

In the past, because the optimizing method considered as the first step the minimization of node voltage deviations and as the second step the minimization of transmission losses within the system, the calculating procedure was more complex and difficult to handle.

This paper presents a new optimizing computational algorithm for the on-line control of system voltage and reactive power flow which aims at minimizing power transmission losses.

The power transmission losses are minimized by a gradient method while satifying the constrained system voltage conditions, and sensitivity parameters are the basis of the method. The practicability of the present approach is proven by the numerical example for the Ward-Hale system and KECO power system (Kyong In area)
