| Popis: | This paper presents a method to derive the optimal offering/bidding strategy of a power producer who owns a hybrid power station (HPS), comprising wind farms (WFs) and pumped-hydro storage. The method is in line with the provisions of the Greek grid code for non-interconnected islands regarding the operation of HPSs. The goal of the HPS producer is to construct a single energy offer/bid for the total daily production/absorption, which maximizes his profits in the day-ahead market and minimizes any imbalance penalties during real-time operation. To this purpose, a two-stage stochastic bilevel optimization model is formulated, where the uncertainty lies in the wind power production of both the WFs belonging to the hybrid producer (internal WFs–IWFs) and the WFs belonging to other independent producers (WFs external to the HPS–EWFs). The upper level of the proposed bilevel model represents the hybrid producer's profit maximization, while the lower level represents the system operator's (SO) market clearing problem. This stochastic bilevel model is finally converted to a mixed-integer linear programming model in order to be tractable. Finally, simulation results from two test cases are thoroughly discussed and useful conclusions are drawn. |
