Complementary operation has been proved an effective way to handle the increasing levels of renewable energy sources (RESs) integration into grid. However, due relative higher forecast uncertainty associated with RESs outputs, when hybrid power system operates according day-ahead plan in real-time, performance may deviate significantly from initial expectation plan. To this problem, study, using wind-hydro (WHHPS) as example, a novel tighten-constraint method is proposed guarantee effectiveness real-time operation. First, conventional planning model and are guide WHHPS. Second, metric, i.e. Reliability, denoted by R, evaluate perspective given inherent prediction errors wind power. Third, data-driven introducing adjustment parameter, λ, improve reliability Finally, bilevel Stackelberg reformulated calculate parameter whole procedure clarified. The then tested verified through series case studies at end paper. results show that (1) can under different reservoir status; (2) high level without adding any additional computation burden; (3) improving precision enhance efficiency resource utilization for generation; (4) over time, increase available historical data accuracy even further.
