Strategies for Wind Power Trading in Sequential Short-Term Electricity Markets

In several countries, independent wind power producers have the possibility to participate in short-term electricity markets for trading their production. However, the limited predictability of the wind resource may lead to differences between produced and contracted energy, thus generating energy imbalances. This may result in the payment of imbalance penalties, which leads to a reduction of the competitiveness of wind power generation. This paper develops a methodology, suitable for independent wind power producers, that permits them to participate in an efficient way simultaneously in several sequential electricity markets, namely day-ahead and intraday markets. The considered intraday market takes place through a continuous trading mechanism. The imbalance cost reduction related to the adjustment participation in the intraday market is assessed using a real-world test case.
