In recent decades, the European postal industry has undergone profound reforms, which aim to promote competition while simultaneously maintaining a high level of universal services for consumers. It is often put forth that market opening and the emergence ...
We study the effect of energy-storage systems in dynamic real-time electricity markets. We consider that demand and renewable generation are stochastic, that real-time production is affected by ramping constraints, and that market players seek to selfishly ...
