A Ready-To-Use Framework for Harvesting Flexibility Using State Estimation and Use-of-System Tariffs: Insights from the H2020 Platone Project

Flexibility from distributed energy resources is a key component in the transformation of modern power systems. Most frameworks, that propose solutions for utilising this flexibility, rely on infrastructure maturity that is not available to most system operators, such as smart metering systems. In this paper, we present a framework for harvesting distribution flexibility which relies solely on data and procedures that system oper-ators can obtain relatively easily, without large infrastructure upgrades. The framework utilises state estimation and implicit flexibility motivation via distribution use-of-system tariffs. A validation setup is designed to measure the efficacy of the proposed framework under realistic conditions using field data. Results show that using the suggested methodology a system operator can harvest 64 % of the available flexibility.
