“…The third module procures reserves using a common market, i.e., bids are accessible to all TSOs. The implementation of the fourth module leads to a common merit-order for the activation of reserve capacity in order to activate the cheapest bids, respecting limits on the connecting transmission lines [17,23,84]. In contrast, the activation of manual frequency restoration reserve (mFRR), i.e., fast tertiary control, is currently still done in a decentralized way, but is based on common rules.…”

“…Although such a component is applied in Germany as well, it does not result in different short and long imbalance prices. The imbalance price is increased for all BRPs if the system is short, and decreased for all BRPs if the system is long [23]. In France, the imbalance price applied to BRP imbalances in the direction of the SI is adjusted by a multiplier 1 + K, set at 1.08 since July 2011 [86].…”

“…In Germany, day-after trading can reduce the uncertainty until the imbalance price is known a few weeks after delivery. However, as shown in [22], there is a high predictability of the approximate level of imbalance prices, rendering this market largely irrelevant in Germany as well [20,23].…”
Short-term electricity markets are generally defined as markets that take place from the day-ahead stage until physical generation and consumption. These markets include dayahead, intra-day, and real-time balancing markets. In Europe, the first two are managed by power exchanges, while the third consists of reserve procurement and imbalance settlement and is operated by the local transmission system operator. Short-term markets are important tools to deal with net demand variability in the system, in which the need for flexibility is expressed and its provision is valorized. Due to the ongoing integration of variable renewables in the generation mix, the system's variability is increasing as a result of the limited controllability and predictability of those resources. As such, these markets become increasingly important. The contribution of this article is a comprehensive upto-date discussion of the key design parameters and functioning of all three short-term markets, and their impact on the demand for and supply of flexibility. An understanding of the design and its implications is useful to policy-makers who are considering changes to facilitate the integration, availability, or valorization of flexibility, while also contributing to the decision-making of flexibility investors and operators. The geographical scope is the Central Western European region, including the Belgian, French, German, and Dutch market zones.

We develop an analytical model to derive the competitive market equilibrium for electricity spot and reserve markets under stochastic demand and uncertain renewable electricity generation. We then derive the welfare-optimal provision of reserves. At rst-best, cost of reserve capacity is balanced against expected cost of outages. The rst-best market equilibrium of the model implies an increase of reserve provision with a growing share of renewable generation. Furthermore, a growing share of renewable generation decreases the level of reliability as measured in energy not served. Additionally, required reserves to balance higher expected deviations will be more expensive, resulting in a trade-o between higher reserve costs and costs of energy not served.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
