“…However, this new energy landscape also enables an unprecedented growing volume of invaluable flexibility 1 (from different voltage levels of the grid) thereby providing essential services (e.g., congestion management and balancing) for transmission system operators (TSOs) and distribution system operators (DSOs). In this respect, the introduction of market mechanisms for the procurement of flexibility from flexibility services provides (FSPs) has been increasingly recommended in policies [1], and has been the center of several recent works in the literature [2]- [7] and demonstration projects [8].…”

In this paper, a transmission-distribution systems flexibility market is introduced, in which system operators (SOs) jointly procure flexibility from different systems to meet their needs (balancing and congestion management) using a common market. This common market is, then, formulated as a cooperative game aiming at identifying a stable and efficient split of costs of the jointly procured flexibility among the participating SOs to incentivize their cooperation. The non-emptiness of the core of this game is then mathematically proven, implying the stability of the game and the naturally-arising incentive for cooperation among the SOs. Several cost allocation mechanisms are then introduced, while characterizing their mathematical properties. Numerical results focusing on an interconnected system (composed of the IEEE 14-bus transmission system and the Matpower 18-bus, 69-bus, and 141-bus distributions systems) showcase the cooperation-induced reduction in systemwide flexibility procurement costs, and identifies the varying costs borne by different SOs under various cost allocations methods.

“…Some works assume that such forecasts are available for each aggregator in a distribution grid [30], for each customer [31], or even for each individual appliance [32]. In addition, some works assume that the costs of deviating from these schedules are available as well [33]. On the one hand, such approaches do not consider the high stochasticity and uncertainty of residential demand [34].…”

“…The authors of [40] propose a LFM to efficiently schedule flexibility for congestion management day ahead. Similarly, in [33] the DSO runs a market right after the day-ahead market clearing, in order to mitigate local congestions. The market in [41] uses a similar approach but considers potential flexibility rebound effects and is designed to work in the yellow phase of the German traffic light system [42].…”

EcoGrid 2.0: A large-scale field trial of a local flexibility market

et al. 2020

The number of distributed energy resources installed in distribution networks is steadily increasing. Their flexibility can be leveraged by aggregators and used in the wholesale markets. However, the utilization of this flexibility cannot neglect the operating conditions of distribution networks, and thus some form of coordination between distribution and transmission system operators must exist. The idea of operating local flexibility markets has been proposed to address these issues, but experience from real-life demonstrations is still missing. The Danish project EcoGrid 2.0 has designed, implemented and tested a local flexibility market with 800 participating customers, which runs in parallel with the wholesale markets. First, this paper presents a method to identify and quantify the value of possible flexibility services that are beneficial to the distribution system operator. Next, it provides insight from the operation of a real local flexibility market, with a large number of controllable loads. Results show that aggregators are able to reliably shape the load of residential heating units to deliver flexibility services, despite the presence of large uncertainties. Services can act as an insurance policy against rare but consequential network overloadings and outages. In these rare cases flexibility services can increase social welfare significantly. However, such services should be carefully selected to avoid adverse effects. Finally, we provide with guidelines and some general remarks on the nature and the desirable characteristics of those markets and services.

“…In [4], the distribution system operator (DSO) pays dynamic subsidies to the customers to solve congestion problems by shifting their energy consumption; whereas the suggested method in [5] relies on dynamic tariffs determined in an iterative way between DSO and aggregators. In [6], a congestion management methodology is suggested for distribution networks while taking into account the rebound effects of demand response units. In this methodology, DSO requests power-cost offers from flexible units in order to manage congestions of the grid after the day-ahead market is cleared.…”

The privatization of distribution systems has resulted in the development of multiple-microgrid (multiple-MG) systems where each microgrid independently operates its local resources. Moreover, the high integration of independent distributed energy sources could lead to operational issues such as grid congestion in future distribution systems. Therefore, this paper provides a transactive-based energy management framework to operate multiple-MG distribution systems; while, alleviating grid congestion in a decentralized manner. In this respect, alternating direction method of multipliers (ADMM) is considered to develop an operational framework that copes with distributed nature of multiple-MG systems. In this context, a novel procedure in the context of ADMM is proposed to distributedly determine transactive coordinator signals which address energy prices as well as power losses and grid congestions. Furthermore, each MG takes into account stochastic programming and the conditional value-at-risk index to handle the uncertainty of its operational scheduling. At last, the proposed framework is applied on IEEE 37-bus and 123-bus test grids to investigate its efficacy in distributed energy management of multiple-MG systems.
