Seamless transition of microgrid between islanded and grid‐connected mode of operation
IET Energy Systems Integration, 2021 Microgrids and their smart interconnection with utility are the major trends of development in the present power system scenario. Inheriting the capability to operate in grid‐connected and islanded mode, the microgrid demands a well‐structured ...

A Practical Fast Acting Control Scheme For Fuzzy Logic-Based Voltage Stabilization Control [PDF]
, 2005 This paper presents a simplified control model for stabilizing a load voltage using a switched reactor in parallel with a fixed capacitor of static VAR compensator. Two IGBT’s are used to control the reactance of the switched reactor.

Power analysis of static VAr compensators [PDF]
International Journal of Electrical Power & Energy Systems, 2008 Analysis of three-phase loads usually assume them to be three impedances in a star or triangle connection. This is the reason why obtained results can only be considered valid for passive loads, strictly speaking. Analysis leading to the proposal of some static compensators is usually performed in this way, which induces to believe that this ...

Variable var compensator circuits [PDF]
, 2006 A family of two reactive-power compensator circuit is presented. A general model of some basic linear elements and switching function blocks is developed first. Then the two proposed compensator circuits are derived from the generalised model.

General-compensation-purpose Static var Compensator prototype
HardwareX, 2019 Static var Compensator (SVC) has a general topology and its operational principle allows its application with distinct compensation purposes, such as voltage regulation or load balancing. Thus, this paper presents the development of a SVC prototype that could be used to test and validate a variety of control strategies proposed for the SVC applications.
