This thesis identifies the conditions under which and quantifies how much society gains from integrating demand response directly into wholesale electricity markets and the level of participation that will bring about these improvements. Furthermore, it identifies the conditions under which the...

Nash equilibrium is usually used as the solution of generator's strategic bidding in electricity markets. The available literature has shown by simulation that multiple market equilibria or no pure equilibrium may be induced after the inclusion of network constraints (transmission constraints)....

Wholesale electricity markets are commonly organized around a spot energy market.Buyers and suppliers submit bids and offers for each hour and the market is cleared atthe price that balances supply and demand. Buyers with bids above the clearing pricepay that price, and suppliers with offers...

El incremento de los precios de la electricidad, que alcanzó su máximo en agosto de 2022, ha afectado de forma diversa a las distintas actividades que se desarrollan en el sector eléctrico español. Este artículo analiza el impacto de dicho incremento sobre el sector, distinguiendo entre...

The increase in electricity prices, which peaked in August 2022, has affected the various activities carried out in the Spanish electricity sector differently. This paper analyses the impact of this increase on the sector, distinguishing between electric power companies and electricity...

Short-term electricity price forecasting is now crucial practice in deregulated electricity markets, as it forms the basis for maximizing the profits of the market participants. In this thesis, short-term electricity prices are forecast using three different predictor schemes, Artificial Neural...
