Providing Curative Distribution Grid Flexibility Using Online Feedback Optimization

IEEE PES Innovative Smart Grid Technologies Europe, pp. 1–5

Abstract

Distribution grid flexibility is regarded as a possible measure in curative system operation, yielding a need for an efficient and robust coordination mechanism for the joint flexibility provision by individual units to the transmission grid. This paper introduces a method to coordinate distribution grid level flexibility as a fast-responding curative measure based on Online Feedback optimization. We utilize an optimization algorithm in a closed loop with the distribution grid to dispatch set points for active and reactive power to flexibility providing units. The approach is evaluated in an experimental setup, utilizing assets connected to an exemplary low voltage grid. Online Feedback optimization is found to be both a viable as well as a highly effective approach to coordinate distributed energy resources in real-time curative system operation.
