Although the optimal power dispatch problem is relatively old, the solution of this problem has not been completed yet. Many methods have been developed and much research has been done on this problem. Some of these methods were practical and most were not. In practice, some methods are being used to optimize the loading of several/many large power plants; most of the [sic] them are old, such as Lambda iteration, Lagrange multipliers, and first and second order gradient methods. Decreasing calculation time is the most crucial part of the problem. That helps getting the generating units adjusted rapidly; therefore, working close to the optimal solution for a longer time, which leads to saving more money. In addition to the old methods, another method, which is called Zoutendijk's is explained in the following chapters. The latter is expected to perform faster than the others, especially for power systems with a large number of generating units. More research and application studies should be done on this problem so that units can operate closer to their optimal points for the longest possible time, therefore decreasing operating costs while meeting the demand and all other constraints.
