Hierarchical Provision of Distribution Grid Flexibility with Online Feedback Optimization
Utilizing distribution grid flexibility for ancillary services requires the coordination and dispatch of requested active and reactive power to a large number of distributed energy resources in underlying grid layers.
Tuning and Testing an Online Feedback Optimization Controller to Provide Curative Distribution Grid Flexibility
A flexibility request from the transmission grid to a distribution grid then needs to be split up onto the different flexibility providing units (FPU) in the distribution grid.
Tuning of Online Feedback Optimization for setpoint tracking in centrifugal compressors
Online Feedback Optimization (OFO) controllers steer a system to its optimal operating point by treating optimization algorithms as auxiliary dynamic systems.
Providing Curative Distribution Grid Flexibility Using Online Feedback Optimization
Distribution grid flexibility is discussed 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.
Deployment of an Online Feedback Optimization Controller for Reactive Power Flow Optimization in a Distribution Grid
Optimization is an essential part of power grid operation and lately, Online Optimization methods have gained traction.
Power Distribution Grid Enhancement via Online Feedback Optimization
In this paper, we use real consumption and generation data on a low-voltage CIGR\'E grid model and an experiment on a real distribution grid feeder to analyze how different Volt/VAr methods can enhance grid capacity, i. e., by how much they can improve the grid's capability to transmit active power without building new lines.
Online Feedback Optimization for Subtransmission Grid Control
The increasing electric power consumption and the shift towards renewable energy resources demand for new ways to operate transmission and subtransmission grids.
Real-time Curative Actions for Power Systems via Online Feedback Optimization
Instead of pre-planning, we propose to calculate these complex curative actions in real-time after the occurrence of a contingency.
Real-time Projected Gradient-based Nonlinear Model Predictive Control with an Application to Anesthesia Control
Medical drug infusion problems pose a combination of challenges such as nonlinearities from physiological models, model uncertainty due to inter- and intra-patient variability, as well as strict safety specifications.
Adaptive Real-Time Grid Operation via Online Feedback Optimization with Sensitivity Estimation
In this paper we propose an approach based on an Online Feedback Optimization (OFO) controller with grid input-output sensitivity estimation for real-time grid operation, e. g., at subsecond time scales.
Experimental Validation of Feedback Optimization in Power Distribution Grids
On a real distribution grid, we compare the local Volt/VAr droop control recommended in recent grid codes, a centralized dispatch based on optimal power flow (OPF) programming, and a feedback optimization (FO) controller that we propose.
Experimental Validation of Fully Distributed Peer-to-Peer Optimal Voltage Control with Minimal Model Requirements
This paper addresses the problem of voltage regulation in a power distribution grid using the reactive power injections of grid-connected power inverters.
