  • Short-term optimization of the new Avče pumping plant and three existing hydropower plants on the Soča river in Slovenia
    Bregar, Zvonko
    In the following years a new pumping plant Avce is going to join the existing cascade of three small-regulating-basin hydro power plants (HPPs) on the Soca river in Slovenia. The pumping plant ... operation will have to be synchronous to the operation of existing plants and vice versa since all four plants depend upon the same inflow and since they all belong to the same generation company that buys and sells electricity to a day-ahead electricity market. The Soca river has torrent alpine characteristics so there are doubts about the operation of the system in frequent dry seasons. As shown in this article. such questions can be effectively solved by first presenting the hydro system of four HPPs under study as a directed graph and then as a mixed integer linear program (M[LP): a set of equations and inequations modeling technical issues of HPPs and a target function (the day-ahead market price) modeling theelectricity market. A small and simple MILP model called Flores has been used for this study. The MILP approach requires only to specify the problem since the solution is found by using availab[e commercial computer solvers. Itcan be applied on-line and it can be augmented to include also the transmission constraints, ancillary services, etc.
