Abstract
The load-frequency control problem for interconnected systems is considered from the viewpoint of optimal stochastic system theory. A control algorithm is developed which provides improved power system performance in both large and small signal modes of operation. An especially attractive feature of the proposed control scheme is that it requires as inputs only the variables currently used, i. e., frequency deviations and scheduled interchange deviations. The classical two-area power system is used as a base system for comparative studies relating the response of an interconnected power system using the new control algorithm to the response obtained using conventional control strategy.Keywords
