Most electricity systems face contractual fixed consumer prices in the short term, that is, load and price are fixed before the random supply of renewables like wind or solar realizes. Steam power plants also make production decisions before such a random supply realizes. These capacities cannot...

Electricity markets are increasingly influenced by variable renewable energy such as wind and solar power with a pronounced weather-induced variability and imperfect predictability. As a result, the evaluation of the capacity value of variable renewable energy, i.e. its contribution to security...

Based upon probabilistic reliability metrics, we develop an optimization model to determine the efficient amount and location of firm generation capacity to achieve reliability targets in multiregional electricity systems. A particular focus lies on the representation and contribution of...
