The study assesses the system impact of wind generation, when wind turbines are equipped with a control system that provides frequency related ancillary services.

The paper suggests a new control strategy for the voltage regulation of unbalanced low-voltage (LV) distribution grids with high DRES penetration.

This text presents an integrated control system which is capable of providing frequency and voltage support to the grid, while operating the Wind Turbine at its optimal point, by utilizing an Energy Storage System.

This paper proposes a precise power flow algorithm for islanded hybrid AC/DC microgrids (HMGs).

The paper suggests two new methodologies to quantify and control the provision of inertial response as ancillary service from active distribution networks.

This paper attempts to define a number of Ancillary Services that can be offered by converter-interfaced DRES and suggests methods for their measurement and quantification.

This paper proposes a novel protection philosophy for distribution grids of low short-circuit capacity and high CI-DRES penetration.

The paper presents a flexible information and communication technology (ICT) architecture to communicate the need for Ancillary Services (AS) from third party providers to the distributed renewable energy sources (DRES) in an efficient and scalable manner and elaborates on the respective requirements.

The paper introduces a new reference frame – the Reduced Reference Frame (RRF) – advancing the performance of the classical transformations of Fortescue, Clarke and Park.

This paper presents a novel approach to control a three-phase four-leg voltage source converter for grid-forming operation.
