A Bilevel Model for Voluntary Demand-Side Flexibility in Distribution Grids

“…Several authors used the bi-level set-up to show how consumers react to different types of tariffs, such as fixed, volumetric or capacity-based tariffs, with different levels of locational and spatial granularity. These studies have highlighted the importance of costreflective distribution tariffs to align consumers' interest with the system needs ( (Schittekatte et al, 2018), (Govaerts et al, 2021), (Schittekatte and Meeus, 2020), (Pediaditis et al, 2021), and (Hoarau and Perez, 2019)). The model we developed in our previous paper, Nouicer et al (2021), was the first to include the option for the DSO to curtail demand for a fixed compensation in a bilevel set-up.…”

Demand-side flexibility in distribution grids: Voluntary versus mandatory contracting

“…Hoarau and Perez (2019) adopt a similar modelling approach to examine the impact of network tariff design on DERs and EVs under a grid cost recovery constraint. Pediaditis et al (2021) consider a detailed representation of the network in a bi-level optimisation model that assesses the impacts of different levels of tariff granularity on the economic efficiency of the short-term operating condition.…”

Synergies between Distribution Use-of-System Tariffs and Local Flexibility Markets

“…Local flexibility markets [3], and capacity limitations in particular, have recently gained attention due to their advantages over energy-based mechanisms [4]. Moreover, traditional DN attributes, such as distribution use-of-system (DUoS) tariffs, were recently re-imagined as a more versatile instrument that serves more than one purpose, including enhancing DER flexibility [5].…”
