从最优随机系统理论的观点出发，研究了互联系统的负荷频率控制问题。一种控制算法的开发，它提供了改进的电力系统性能在大信号和小信号操作模式。所提出的控制方案的一个特别有吸引力的特点是，它只需要作为输入的变量当前使用，即。例如，频率偏差和预定交换偏差。经典的两个区域的电力系统被用来作为一个基础系统的比较研究有关的互联电力系统的响应，使用新的控制算法，使用传统的控制策略得到的响应。
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.
