Dynamic grid impedance calculation in D-Q frame for micro-grids

2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY, 2014
This paper presents a method for online dynamic measurement of the grid impedance that may prevail in an electrical network at any instant of time. Here the grid resistance and inductance are measured during the operation using a non-characteristic frequency current continuously injected into the grid, and subsequently calculating the impedance using ...

Grid voltage control with distributed generation using online grid impedance estimation

Sustainable Energy, Grids and Networks, 2016
Abstract Distributed generation (DG) units usually do not participate in the grid voltage control and inject power regardless of the grid voltage. Only when the grid voltage level surpasses a certain threshold, these units shut down to avoid any damage.

Real-time grid impedance estimation technique for grid-connected power converters

2012 IEEE International Symposium on Industrial Electronics, 2012
Grid impedance is one of the most important parameters for operating and controlling of grid-connected converters, especially with the high penetration of renewable energy sources into microgrid and smart grid. One of the technical challenges is how to fast and accurately estimate the grid impedance, even under the distorted and unbalanced conditions ...
