| Abstract | The new rules of the electrical energy production market operation of the Iberic Electricity Market MIBEL (mainland Spanish and Portuguese systems), for the diary and intra-diary market (July 2007), bring new challenges in the modeling and solution of the production market operation. Aiming to increase the proportion of electricity that is purchased through bilateral contracts with duration of several months and intending to stimulate liquidity in forward electricity markets, the Royal Decree 1634/2006, dated December 29th, 2006 imposes to Endesa and Iberdrola (the two dominant utility companies in the Spanish peninsular Markets) to hold a series of five auctions offering virtual power plant (VPP) capacity to any party who is a member of the MIBEL. Other experience of the application of VPP auctions can be seen in France, Belgium and Germany. In Spain, the VPP capacity means that the buyer of this product will have the capacity to generate MWh at his disposal. The buyer can exercise the right to produce against an exercise price that is set in advance, by paying an option premium. So although Endesa and Iberdrola still own the power plants, part of their capacity to produce will be at the disposal of the buyers of VPP. VPP capacity is represented by a set of hourly call options giving the buyer the right to nominate energy for delivery at a pre-defined exercise price. There will be baseload and peakload contracts with different exercise prices. The energy resulting from the exercise of the VPP options can be used by buyers in several ways: (a) national and international bilateral contracts prior to the day-ahead market; (b) bids to the day-ahead market and (c) national bilateral contracts after the day-ahead market. In order to operate the VPP options each buyer agent will have a Generic Unit (GU). This work develops an stochastic programming model for a Generation Company (GenCo) to find the optimal management of a VPP in the day-ahead electricity market under the most recent bilateral contracts regulation rules of MIBEL energy market. |
