Collaboration agreement with the Catalonia Institute for Energy Research

Tue, 12/28/2010 - 20:01 — admin

Last December 15 I visited, together with the members of the energy team of the GNOM research group, the headquarters of the Catalonia Institute for Energy Research. The board of this institution is comprised by representatives of the Spanish and Catalonian governments, catalonian universities and private sector companies, and its mission is to promote the research in the energy field and the dissemination of this research in collaboration with several major Spanish energy utilities.

The objective of the meeting was to undertake common research projects related the integration of renewevable energies in the electricity production system, specifically in the optimal management of microgrids and the design of the transmission network of offshore wind farm.

AbstractA Generation Company (GenCo) can participate in the Iberian Electricity Market (MIBEL) through different mechanisms and pools: the bilateral contracts, the physical derivatives products at the Derivatives Market, the bids to the Day-Ahead Market, the Intraday Markets or the Ancillary Services Markets. From the short-term generation planning point of view, the most important problem to solve is the bidding strategy for the Day-Ahead Market (DAM) given that the 85% of the physical energy traded in Spain is negotiated in it, but this participation cannot be tackled independently of other subsequent markets.

AbstractWe consider a generation company operating in the liberalized electricity market, whose production system consists of hydro and thermal plants. Production is sold either directly to customers, by means of bilateral contracts, or on the spot market, where the electricity price is unknow until the market clearing process has taken place. Price risk may be hedged by financial tools provided by the Derivative Electricity Market. In this work futures contracts are considered, i.e. agreements to sell electricity in the future for a specified price. A Mixed Integer Linear Programming model is introduced for determining the unit commitment of thermal units and the dispatchment of available thermal units and hydro plants, aiming at maximizing profits. Numerical results on a case study are reported

Conference on Numerical Optimization and Applications in Engineering (NUMOPEN-2010)

Fri, 10/15/2010 - 18:29 — admin

The Centre de Recerca Matemàtica   (Center for Mathematical Research) organized on October 13 and 14 the Conference on Numerical Optimization and Applications in Engineering. The workshop provided a forum for researchers working on different aspects of optimization to present their recent discoveries, and to interact with people working on complementary aspects of optimization and mathematical programming. I was kindly invited to present the talk "Electricity Market Optimization: finding the best bid through stochastic programming".

AbstractThe participation in national and international electricity markets has became a very complex decision making process. Electrical utilities participating in such liberalized market have to decide daily the operation, generation scheduling and optimal bid of each one of their generation units in several consecutives day-ahead markets. In the talk, we will describe the operation rules of the Iberian Electricity Market (MIBEL), how this operation can be mathematically modelled with the help of stochastic programming into large scale nonlinear integer problems and how these difficult optimization problems can be solved with specialised algorithms. Finally, the results found for several cases with real data of Spanish utilities and MIBEL market prices will be shown.

AbstractThe electric market regulation in Spain (MIBEL) establishes the rules for bilateral contracts in the day-ahead optimal bid problem. Our model allows a price-taker generation company to decide the unit commitment of the thermal units, the economic dispatch of the bilateral contracts between the thermal units and the optimal sale bids for the thermal units observing the MIBEL regulation. The uncertainty of the spot prices is represented through scenario sets. We solve this model as a deterministic MIQP problem by using perspective cuts to improve the performance of Branch and Cut. Numerical results are reported.
