Abstract (EN):
The restructuring of power systems induced new
challenges to generation companies in terms of adequately
planning the operation of power stations in order to maximize
their profits. In this scope, hydro resources are becoming
extremely valuable given the revenues that their operation can
generate. In this paper we describe the application of the
Matlab® Linprog optimization function to solve the Short Term
Hydro Scheduling Problem, HSP, admitting that some stations
are installed in the same cascade and that some of them have
pumping capabilities. The optimization module to solve the HSP
problem is then integrated in an iterative process to take into
account the impact that the operation decisions regarding the
hydro stations under analysis have on the market prices. The
updated market prices are then used to run again the HSP
problem thus enabling considering the hydro stations as price
makers. The developed approach is illustrated using a system
based on the Portuguese Douro River cascade that includes 9
hydro stations (4 of them are pumping stations) and a total
installed capacity of 1485 MW.
