Grid-Forming Converters for Stability Issues in Future Power Grids

Power Converters for Grid Integration of Wind Power Systems

This paper presents the different power converters for grid integration of wind power systems. In wind power systems while integrating with grid, power quality issues are becoming more predominant. This can solve by using power electronics converters like two level back to back converter and matrix converters. Converters are compared on the basis of efficiencies, voltage conversion ratios and T...

Issues in Model Reduction of Power Grids

Power grid analysis has recently risen to prominence due to the widespread use of lower supply voltages by power-conscious designs. Low supply voltages imply smaller noise margins and make the voltage drop across the power grid very critical since it can lead to overall slower circuits, signal integrity issues and ultimately to circuit malfunction. Verifying proper behavior of a power grid is a...

Generalized-impedance and Stability Criterion for Grid-connected Converters

The output impedance matrix of a grid-connected converter plays an important role in analyzing system stability. Due to the dynamics of the DC-link control and the phase locked loop (PLL), the output impedance matrices of the converter and grid are difficult to be diagonally decoupled simultaneously, neither in the dq domain nor in the phase domain. It weakens the effectiveness of impedance-bas...

Grid Mind: Prolog-Based Simulation Environment for Future Energy Grids

Fundamental changes in the current energy grids, towards the so called smart grids, initiated a range of projects involving extensive deployment of metering and control devices into the grid infrastructure. Since in many countries, the choice of supportive information and communication technologies (ICT) for the grid devices still remains an open question, benchmarking tools aimed at predicting...
