Demonstrating the Mas2tering solutions
In the MAS2TERING smart grid conceptual framework, the prosumer is the provider of flexibility and is part of a local community of prosumers. The community is composed by prosumers all belonging to the same local area (a portion of LV grid) and represented by the same Local Flexibility Aggregator (LFA). The “local” aspect of this community is the focus and added value of MAS2TERING. Flexibility is not only aggregated in a central way by wholesale market aggregators (representing huge portfolios of prosumers); in MAS2TERING it is first used by prosumers of the community for in-home optimization and then traded at local level both to bring added value to prosumers and LFA and to support DSOs in congestions management. The local optimization of flexibility is enabled by the MAS2TERING key technologies (Energy Box), tools (MAS optimization) and services (cyber security) and is based on the market-based mechanism envisioned by the Universal Smart Energy Framework (USEF), which has been extended and adapted to the MAS2TERING case.
This MAS2TERING smart grid conceptual framework has been used to frame the refinement phase and give concreteness to the UCs. Global objectives for each of them are provided in the following table:
|Use Case||Global objective of the 3 Mas2tering Use Cases (UCs1-3)|
|This UC focuses on the Home Area Network (HAN) and the services that involve the prosumer; the scope is to demonstrate the interoperability between the HAN management system, the smart meter and the Energy Box, which enables consumption profile optimization and allows the bi-directional communication between the prosumer and the rest of the LV grid. The enabled communication is a prerequisite to the local optimization proposed in the other UCs and, for the prosumer, to enter the market of flexibility products.|
|This UC focuses on the local community of prosumers represented by a Local Flexibility Aggregator in a local area of the LV grid; the scope is to demonstrate that MAS optimization performed at this local level is effective for energy management and local balancing, as an alternative to traditional centralised optimization. The objective is to maximise revenue for prosumers belonging to the local community when coping with variable external conditions but not considering grid-related constraints.|
|The last UC can be considered as an extension of UC2 and tackles the LV grid, intended as the union of local communities of prosumers in a given area (represented by a MV/LV substation). The UC targets in particular DSOs and aims at demonstrating that the local optimization enabled in UC2, coupled with appropriate grid monitoring can be a cost-effective way to deal with local congestions and globally increase grid performances, reliability and resilience.|
As shown in Table 1 above (and further detailed in the next paragraphs), the three refined UCs fully support and align with the MAS2TERING smart grid conceptual framework (See Annex B for details). Figure 1 below also shows a graphic representation of the scope of the MAS2TERING framework and the areas targeted by each individual UC.
Figure 1: Use Cases within the MAS2TERING framework
As shown in Figure 1 above, each use case deals with a specific portion of the LV grid (i.e. the HAN, the local community of prosumers and the LV grid). As further detailed in the next paragraphs, starting from use case 1, each use case is an enabler to the subsequent one, for each analyses portions of the LV distribution network that were gradually wider.
The refined Use Cases support the MAS2TERING framework and are aligned with the project’s storyline and business vision. As summarized in the following table, each refined UC is characterized by specific quantified objectives, required to demonstrate the effectiveness of the solution proposed in MAS2TERING:
|Use Case||Quantified objectives|
|UC1||– Secure and effective communication between HAN monitoring and management devices;
– Minimization of costs associated with the energy bill for the prosumer using MAS.
|UC2||– Maximization of revenue for the prosumers belonging to the community using MAS with or without external requests. Revenue consists of both reduction of costs associated to energy consumption and additional income due to trade of flexibility;
– Peak load reduction in the local community resulting from maximization of revenue for the prosumers belonging to the local community using MAS;
– Self-consumption in the local community resulting from maximization of revenue for the prosumers belonging to the local community using MAS;
|UC3||– Enhanced LV grid performances through reduction of LV grid losses (in the region of 5-7%, but anyway dependent on the targeted penetration of smart technologies)
– Renewable grid hosting capacity increased by 12-15%;
– Increased reliability of the grid expressed in terms of effectiveness of the local optimization in enabling congestion management;
Finally, as reported in Figure 2 below, it can be noted that the three refined Use Cases are also well aligned with the storyline introduced in D1.6, which has been the starting point for the development of the MAS2TERING business vision. In particular, UC1, that targets the prosumer and the HAN, is fully aligned with the first phase of the storyline; UC2, which focuses on the local community of prosumers and the local optimisation, is fully aligned with the second phase of the storyline; UC3, which targets the LV grid and the DSO, is fully aligned with and also extends the third phase of the storyline by including more local communities of prosumers.

Each of the UCs is also associated with specific scenarios. These will be implemented in representative contexts as part of the demonstration activities and used to evaluate specific services or functionalities of the MAS2TERING platform.
