Self-scheduling of a wind producer based on Information Gap Decision Theory

In a competitive market where all producers must participate in the market, WPPs (wind power producers) face two sources of uncertainty: (i) future market prices, and (ii) their production capability in coming hours. In this paper a risk-constrained optimal self-scheduling method for a WPP considering the uncertainty associated with market prices and wind generation is proposed. IGDT (Information Gap Decision Theory) is used to address theses uncertainties in WPP's self-scheduling. The proposed IGDT-based model is a bilevel programming approach, which is transformed to an equivalent single level bilinear programming model that can be solved using available solvers. Numerical simulations and discussions are provided.
