Introduction and Objectives

The GNOM research group of the UPC team has continuously participated in research projects funded by the MEC-CICYT since 1999, always in the field of optimal electricity generation planning. In the last two projects,  project DPI2002-03330 and DPI2005-09117-C02-01, we formulated and implemented mathematical models and algorithms for the optimization of the electric power generation planning in the short term (one week) and in the medium term (one year) of a generation company operating in a competitive market. The radical changes occurred in Spanish energy market regulation during the last three years, starting with  the MIBEL (Iberian Electricity Market), forces the existing models to be adapted to known operating rules and opportunities. The project that is proposed here aims at several new features:
  • The joint optimization of the "multimarket" nature of the MIBEL organization, with a portfolio of markets (futures, day-ahead, reserve, intradiary, VPP, etc.) and physical bilateral contracts, both in medium-and short-term planning.
  • The inclusion of "environmental constraints" in the optimization models, through the precise formulation of emissions, in such a way that will permit each emission technology (wind, solar, hydraulics, combined-cycle, thermal) to be used in the optimally.
  • Several stochastic variables, such as energy price, fuel price, natural inflows, etc., must be precisely modelled in order to formulate accurate stochastic programming models.
  • The different market problems were solved separately in previous projects. The multimarket model proposed in this project aims to simultaneously optimize all of  these related markets, posing new optimization challenges that must be undertaken both with commercial optimization software and, when necessary, with specialized interior point and dual decomposition algorithms for mixed nonlinear optimization. Such strategies will also be developed within this project.
Finally, due to the applied orientation of the fundamental research of this project, both the models and the algorithms developed should be validated with the help of real data provided by Unión Fenosa and Gas Natural, which are two of the most prominent electrical utilities in the Spanish electricity market.
