Abstract	The objective of this work is to find an optimal commercial strategy in the production market that would allow wind producer to maximize their daily profit. That can be achieved on one hand, increasing incomes in day-ahead and intraday markets, on the other hand, reducing deviation costs due to error in generation predictions.

Abstract	The 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 on the framework of the Branch and Fix Coordination metodology as a quadratic, two-stage stochastic problem. Numerical results are reported.

Abstract	In view of the changing energy paradigm in which we find ourselves, where concepts such as the security of supplies, the environment and energy efficiency have drastically changed the political and social model applied to conventional sources of energy, what will be the energy challenges over the next few years? Given the various alternatives currently possible for changing sources of energy supply and the business models in place with regard to consumption, how can we anticipate future developments? Which options will be most successful? What are the technological challenges that the best universities, the best research centres and the best businesses are trying to overcome? To what degree can we anticipate the future focus of energy innovation? It is these and other questions on which we will focus and attempt to answer at the conference: Barcelona Global Energy Challenges, which will be attended by lecturers from MIT, and the most representative businesses and organisations from the energy sector that are spearheading the changes in this technological model. This is the sixth edition of the Barcelona Global Energy Challenges, which, once again, will take place in Barcelona on the 2nd and 3rd of June.

Last June 2 and 3 I was attending the Barcelona Global Energy Challenges conference that was held in Barcelona. It was the sixth edition of a forum co-organized by the  MIT Industrial Liason Program (MITILP), the Institute for the Energy Research of Catalonia (IREC) and the b_TEC foundation (b_TEC). In view of the current energy paradigm shift, representatives from the key institutions leading changes in technology and energy will answer questions like: What are the technological challenges facing top research centers and universities? How will the energy future unfold? What will the most successful options be? What areas will be the focus of energy innovation?

Abstract	Short-term electricity market is made up of a sequence of markets, that is, it is a multimarket enviroment. In the case of the Iberian Energy Market the sequence of major short-term electricity markets are the day-ahead market, the ancillary service market or secondary reserve market (henceforth reserve market), and a set of six intraday markets. Generation Companies (GenCos) that participate in the electricity market could increase their benefits by jointly optimizing their participation in this sequence of electricity markets. This work proposes a stochastic programming model that gives the GenCo the optimal bidding strategy for the day-ahead market (DAM), which considers the benefits and costs of participating in the subsequent markets and which includes both physical futures contracts and bilateral contracts.

Key Words	research; DPI2008-02153; electricity markets; TSFA; spot price scenarios; paper
Abstract	In liberalized electricity markets, Generation Companies must build an hourly bid that is sent to the market operator. The price at which the energy will be paid is unknown during the bidding process and has to be forecast. In this work we apply forecasting factor models to this framework and study its suitability.

Dr. Marcos J. Rider and Dr. Marina Lavorato, both professors of the dept. of electrical engineering of the Univ. Estadual Paulista, UNESP, (Brasil), have been visiting the GNOM site in Barcelona during January as a part of their participation on the research project DPI2008-02153. We are collaborating in the development of  new stochastic programming models for the optimal expansion of the transmision network in electricity markets. They already visited our group on 2008, and we expect to continue this collaboration in the future reinforcing the relationship between GNOM and the UNESP, both in research and postgraduate tuition.

 

PD: Dr. Rider won last week a permanent position of associate lecturer in the UNESP. Congratulations Marcos!!

Abstract	The start-up of the Iberian Electricity Market introduced a set of new mechanisms in the Spanish electricity sector that forced the agents participating in the market to change their management policies. This situation created a great opportunity for studying the bidding strategies of the generation companies in this new framework. This thesis focuses on the short-term bidding strategies of a price-taker generation company that bids daily in the Iberian Electricity Market. We will center our bidding strategies on the day-ahead market because 80% of the electricity that is consumed daily in Spain is negotiated there and also because it is the market where the new mechanisms are integrated. One of the main contributions of this thesis has been the study the Spanish electricity price time series and its modeling by means of factor models. In this thesis, the new mechanism introduced by the Iberian Market that afects the physical operation of the units is described. In particular, it considers in great detail the inclusion of the physical futures contracts and the bilateral contracts into the day-ahead market bid of the generation companies. The rules of the market operator have been explicitly taken into account within the mathematical models, along with all the classical operational constraints that afect the thermal and combined cycle units. The expression of the optimal bidding functions are derived and proved. Once these main objectives were fullfiled, we improved the previous models with an approach to the modeling of the influence that the sequence of very short markets have on optimal day-ahead bidding. These markets are cleared just before and during the day in which the electricity will be consumed and the opportunity to obtain benefit from them changes the optimal day-ahead bidding strategies of the generation company, as it has been shown in this thesis. The entire models presented in this work have been tested using real data from a generation company and Spanish electricity prices. Suitable results have been obtained and discussed.

Abstract	This paper develops a stochastic programming model that integrates the most recent regulation rules of the Spanish peninsular system for bilateral contracts in the dayahead optimal bid problem. Our model allows a price-taker generation company to decide the unit commitment of the thermal and combined cycle programming units, the economic dispatch of the bilateral contract between all the programming units and the optimal sale bid by observing the Spanish peninsular regulation. The model was solved using real data of a typical generation company and a set of scenarios for the Spanish market price. The results are reported and analyzed. The main contributions of this paper include: (a) a new model for the optimal bid function and matched energy for thermal and CC units, (b) a new and detailed mixed-integer formulation of the operation rules of the CC units and (c) the joint optimization of all the above-mentioned factors together with the BC duties. The model was tested with real data of market prices and programming units of a GenCo operating in the Spanish electricity market.
