N2 - Mixed integer linear programming (MILP) models have in the last decade gained considerable interest in simulation of deregulated electricity markets 1,2. They are based on an in-depth knowledge of all relavant technical characteristics (for example a cascade of hydro power plants), of the current state (for example the regulating basins states), and the forecast of external parameters (for example the 24 hours inflows forecast) of the system under study, and the hour-by-hour forecast of the electricity marginal price for the following day 8. Similar as in the linear programming (LP) models, in MILPs, too, all technical operation limitations are expressed as a set of linear equations and inequations. The optimization function in MILPs remains linear and is usually expressed as the maximum of the expected revenue from the electricity market. It is very important to note that some variables in MILPs can be of the integer type which allows far better modelling of system technical characteristics then in LPs. When applying MILPs, one does not ussually do the math since it suffices to use the available computer solvers. This paper presents the theory of the new MILP Flores model that has been developed at the Milan Vidmar Electric Power Research Institute. It is based on the Institute's PRAK model that calculates the hydra cascades production 17. The know-how follows the general LP energy flow MESSAGE model of the International Atomic Energy Agency 18. Two examples are added: the cascade of three existing runof- river plants on the Soca river including the new pumping hydro plant Avce 14 and the weeldy-cycle cascade of the two rehabilitated plants Moste II+ III on the upper Sava river 15.
