OPTIMAL POWER REPARTITION BETWEEN UNITS OF A HYDRO POWER PLANT
The paper presents a methodology for the operation of those hydro power plants provided with more penstocks and more units by the optimal distribution of the dispatched power among its available generating units, aiming at the maximum efficiency of the completely hydro power plant energy conversion. Considering the unit operating characteristics as unequal at different head levels, the authors propose a modern program of optimal distribution of power between the units of a hydro power plant to take into account the real characteristics and real head for each unit to define the actual performance specifications. Further, this information can be utilized in the optimization process to minimize water expenditure at hydropower plant.
