LQR-Based Adaptive Virtual Synchronous Machine for Power Systems With High Inverter Penetration

This paper presents a novel virtual synchronous machine controller for converters in power systems with a high share of renewable resources. Using a linear quadratic regulator-based optimization technique, the optimal state feedback gain is …

TDNetGen: An Open-Source, Parametrizable, Large-Scale, Transmission, and Distribution Test System

In this paper, an open-source MATLAB toolbox is presented that is able to generate synthetic, combined transmission, and distribution network models. These can be used to analyse the interactions between transmission and multiple distribution …

Active Distribution Grids offering Ancillary Services in Islanded and Grid-connected Mode

Future active distribution grids (ADGs) will incorporate a plethora of Distributed Generators (DGs) and other Distributed Energy Resources (DERs), allowing them to provide ancillary services in grid-connected mode and, if necessary, operate in an …

Online Estimation of Power System Inertia Using Dynamic Regressor Extension and Mixing

The increasing penetration of power-electronic-interfaced devices is expected to have a significant effect on the overall system inertia and a crucial impact on the system dynamics. In the future, the reduction of inertia will have drastic …

Contribution of Distribution Network Control to Voltage Stability: A Case Study

A case study dealing with long-term voltage instability in systems hosting active distribution networks (DN) is reported in this paper. It anticipates future situations with high penetration of dispersed generation (DG), where the latter are used to …
