A quota-based approach can help grid operators deal with congestions in distribution grids in a non-discriminatory way for customers. The quota limits the maximum feed-in or consumption of a group of flexibility providing units (FPU) within a grid cluster. The novel iterative quota calculation (IQC) method is introduced in this paper. In this approach, the maximal active power limits of the FPU are constantly adapted, and the feasible operating region (FOR) of the grid is computed. The quota is computed from the resulting FORs after ensuring that the FPU operation cannot cause grid instability. The proposed method is compared to a previously developed static approach in a real LV grid. Results show the benefits of adding reactive power to the quota calculation, especially in distribution grids with inadequate reactive power compensation.

... Paper [4] shows load reduction results due to predictive consumption management using the V2G (Vehicle to Grid) approach. The prediction procedure and technology for the control of conges low-voltage networks are described in reference [5]. An example of a solution for peak load reduction through e-mobility smart tariffs is described in the paper [6]. ...

... Spertino et al. (2022) aimed for optimal voltage control in LV networks with the aid of on-load tap changers and PV inverters, while Jayasekara et al. (2015) developed a multi-objective optimization problem to locate BESSs optimally in distribution networks. Contreras et al. (2022) developed an interaction quota method to maintain the possible congestion and grid use in an optimal way. Delfino et al. (2019) presented an energy management model enabling control of active and reactive powers in MV/LV microgrids. ...

... A first practical implementation of a quota-based congestion management system in LV grids was proposed in the "grid-control" research project ( [4]). The follow-up project "flexQgrid" focuses on further improving of the quota system and implementing it in a large-scale field test ( [5] and [6]). Different approaches to compute and enforce non-discriminatory quotas for active power injection have been proposed in both projects, with a strong focus on their practical implementation based on load and generation forecasts. ...
