This paper presents an improved genetic algorithm(GA) based on the decimal system for hydropower station reservoir optimal operation, because binary code is liable to cause code redundancy problem. This method adopts a population of points at a time, and guarantee to find the global optimum quickly, and a lot of memory is saved. An example proved that the GA is simple and easy to use, and could avoid the dimension problem.
