“…The demand side is expected to have a new, active role in maintaining the supply-demand balance by providing flexibility in its demand profile. Relying on distribution grid investments alone to solve the above difficulties would be very costly, while monitoring and control solutions could complement investments cost-effectively [1]. Flexibility on the user side is deemed the key to implementing active management solutions for better utilization of distribution grids to reduce the impact of limited grid capabilities.…”

“…The flexibility is the change of prosumer's demand profile; it is a flexibility product, which can be provided to electricity industry participants requiring grid services [1]; to procure flexibility services, market-based approaches are the preferred choice. Distribution System Operators (DSOs) shall procure flexibility in ancillary services markets from prosumers such as distributed generation, storage, and demand response [3], comprehensively referred to as Distributed Energy Resources (DERs), either individually or in an aggregated form; the markets for ancillary services for distribution systems are being or have just started [4]- [9].…”

The flexibility provided by prosumers is recognized as a key element for the management of the electrical grids, in particular distribution grids, in the changing scenario of electricity generation and consumption. The flexibility useful to Distribution System Operators (DSOs) is strongly local, and it is necessary to identify the busses of the grid where the flexibility can be usefully provided for a service requested by the DSO. For this purpose, the concept of flexibility perimeter is adopted; it is defined as a set of busses such that flexibility can be provided by any set of prosumers within it while the grid operation remains secure. The flexibility perimeter is a relevant concept for flexibility markets; in particular, for aggregators, since the flexibility provided by the prosumers within the perimeter can be offered as a single product to participants to electricity markets requiring grid services. The identification of flexibility aggregation perimeters for congestion-relief services in a radial grid is straightforward; for flexibility services intended to solve voltage profile problems, the identification of perimeters is not easy, even in radial grids. The paper proposes a method for the identification and evaluation of flexibility perimeters for grid services in radial distribution grids, based on the concept of Load Area; it can help decision-makers choose a compromise between technical and market efficiency of the aggregation perimeter dimension.
