Abstract
To operate a large-scale hydropower production system in an ever-changing environment, operating rules are a convenient way of communication between short-term planners and real-time dispatchers. This articles presents a new form of operating rules, and a solution approach to solve the short-term planning problem directly in the space of rules. Our operating rules are designed to handle complex hydro-valleys and highly constrained reservoirs. Our solution approach is based on tabu search and easily implemented. Uncertainty on inflows and electrical load is represented in the mathematical model via a 2-stage scenario tree. Numerical experiments on real instances from Hydro-Québec show that our approach is able to find good stochastic solutions while respecting the operational timing, and it improves the objective value by up to 54% in instances with moderate to high inflows.
