A Combined High-, Medium-, and Low-Voltage Test System for Stability Studies with DERs

Future scenarios with high penetration of Distributed Energy Resources (DERs) call out for detailed network modelling at all voltage levels. The challenges of building a network model that is realistic at both the transmission and distribution levels …

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 …

Data-Driven Local Control Design for Active Distribution Grids Using Off-Line Optimal Power Flow and Machine Learning Techniques

The optimal control of distribution networks often requires monitoring and communication infrastructure, either centralized or distributed. However, most of the current distribution systems lack this kind of infrastructure and rely on sub-optimal, …

Data-driven Control Design Schemes in Active Distribution Grids: Capabilities and Challenges

Today, system operators rely on local control of distributed energy resources (DERs), such as photovoltaic units, wind turbines and batteries, to increase operational flexibility. These schemes offer a communication-free, robust, cheap, but rather …

Hybrid approach for planning and operating active distribution grids

This paper investigates the planning and operational processes of modern distribution networks hosting distributed energy resources (DERs). While in the past the two aspects have been distinct, a methodology is proposed in this paper to co-optimise …
