“…As networks operation approaches thermal and voltage limits, the DSO is increasingly being called on to actively manage network congestion, as an alternative to costly network reinforcement. Recent EU funded academic projects to develop models for the DSO as active system operator, include: SmartNet [11], Ecogrid 2.0 [12], [13] and INVADE [1]. Furthermore, the Universal Smart Energy Framework (USEF) [14], which is being implemented in an industry DSO flexibility market trial [15], provides a detailed framework for DSO flexibility markets with the aggregator as the central market actor.…”

Increasing penetrations of small scale electricity generation and storage technologies are making an important contribution to the decentralisation and decarbonisation of power system control and operation. Although not currently realised, coordination of local distributed energy resources (DERs) and a greater degree of demand flexibility through digital aggregation, offer the potential to lower the cost of energy at source and to enable remuneration for consumer participation, addressing the rising costs of energy supply, which impacts strongly on all consumers. Methods are required to manage potential distribution network constraints caused by flexible DERs, as well as for determining the risk to delivery of flexibility from these DERs for aggregators. A heuristic network flexibility dispatch methodology is proposed, which can be used to calculate the probability of constraints, and any required adjustments of flexible agent positions to resolve them, at half hourly resolution. The aggregator can use this methodology to manage their portfolio risk, while a distribution system operator can estimate required flexibility to manage constraints down to low voltage level.

“…Kirschen (2003) provides an overview of the potential benefits of better accounting for demand-side flexibility in future wholesale market designs. In addition, O'Connell et al (2016), Liu et al (2015), and Bobo et al (2018) highlight the need for new trading mechanisms, such as flexibility-oriented products and extended bid formats, that facilitate market access to prosumers, and reveal the value of their operational flexibility in a market environment. Additionally, policy-makers and market operators lack a better understanding of the motivations and behavior of prosumers to effectively and efficiently integrate them into electricity markets (Stern, 1992;Allcott & Mullainathan, 2010;Gyamfi et al, 2013;Da Silva et al, 2012;Lampropoulos et al, 2010).…”

“…These bids consist of several single offers linked to each other, submitted at the same time and location but with different direction, quantities and prices, and referred to different time targets. Papers [10]- [12] present different approaches to provide flexibility from the demand side through this type of bids. Thermal electric loads such as building heating and cooling, water heating and refrigeration are ideal candidates for load shifting, as they can vary their energy consumption without compromising their purpose [10].…”

Flexibility markets can be introduced as a tool for the distribution system operator (DSO) to avoid high costs and public opposition against new network investments. Continuous flexibility markets have the advantage of allowing more liquidity, which can be critical in the earlier stages of such markets, and can be operated closer to real-time, thereby enabling a better use of the latest forecasts; but, by design, they also result to a lower social welfare compared to auction-based markets. This paper has two main contributions. First, it introduces a continuous local flexibility market which includes both network constraints and asymmetric block bids. Second, it proposes an algorithm that can accurately determine the upper and lower bound of the social welfare loss compared with an auction-based clearing model.
