The electric power and energy balance method is a basic technique of determining the installed capacity in the planning and design of hydro plants. The outstanding characteristics of this method in short- term operation of hydro-electricity system are summarized. The principle of this method is very simple.It can reasonably solve the problems of the generating set in continuous opening and stopping and effectively reduce computation time. This paper puts forward the algorithm of this method and presents the application methods in solving the mathematical model for short-term optimal operation of hydro plant group,which provides the basis for the development of computer software system.
