Abstract Formerly the algorithm, which is based on sensitivity and used in active power security correction, has too much focus on the calculation of sensitivity. In addition, the adjusting orders of units or loads are formed only in accordance with the value of sensitivity, but not taking the fact into consideration which the power injection of the same node influences various branches power flow in different ways. Nowadays, there is a new development of methods to figure out the power adjustment quantity of control nodes. The algorithm, based on sensitivity and equal and opposite quantities in pairs, find its way to calculate the adjustment quantity. On this basis, the paper proposes a new method of active power correction control decision analysis method by using cross-weight factor, parallel with equal and opposite quantities in pairs. For the overload lines, this method takes into account the same node’s different influence on various lines that is illustrated by the value of sensitivity, and then finish the optimal selection of control node or its combination. So in this way, not only can the requirement of frequency generators’ output level be decreased as eliminating the overload branch circuit, but also normal lines are prevented from either the performance of overload or the repeat adjustment. Finally the intelligent adjustment control calculation of active power comes to the truth.

Key words： Equal and opposite quantities in pairs cross-weight overload active power correction
