Abstract

A large contribution to the total share of electricity generated in European power grid will come from renewable sources of energy soon due to European initiative to become carbon neutral. Renewable Energy Sources (RES) are connected to the grid with Power Electronic (PE) devices, which, if not modelled correctly, provide low confidence in the assessment of the overall system stability. The aim of the paper is twofold; firstly, to evaluate the impacts of Wide Area Monitoring System (WAMS) on grid-forming control with Direct Voltage Control (DVC) and Virtual Synchronous Machine (VSM). Secondly, to perform Modal / Eigenvalue analysis to evaluate the effect of WAMS on selective damping. Modal analysis will be conducted and will serve as a base for calculating matrices B and C. Left and right eigenvectors will enable determination of Controllability and Observability Indices. Damping controller is designed to receive three signals from Phasor Measurement Units (PMUs) and feed the reference signal to the high impact generator. System studied is a modified IEEE 39 New England Bus with two synchronous generators and eight RES. Activation of the damping controllers showed significant improvements in time-domain simulations on overall damping and Eigenvalue confirmed the results by studying the damping ratios of critical modes.
