Application of operations research in automatic generation control of hydropower plants

An algorithm is presented to solve the problem of automatic generation control (AGC) for hydropower plants stage by stage, using in each stage a different method of operations research: dynamic programming, 0-1 integer programming, and the principle of equal incremental. The algorithm has the following advantages: short time of calculation, less computer memory required, the ability to take aspects of economic and safety requirements into consideration, flexibility, etc. This algorithm is suitable for real-time AGC. A brief description of the realization of AGC in the left powerhouse of the Gezhouba Hydropower Plant is presented
