Evaluation of reactive power support in solar PV prosumer grid
e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2022 Electricity prosumption is gaining ground due to price reduction in solar PV systems. The presence of prosumers on the low voltage grid is said to compromise power quality in the grid.

Reliability model for a Static Var Compensator [PDF]
2017 IEEE Second Ecuador Technical Chapters Meeting (ETCM), 2017 This paper presents a reliability model of a Static Var Compensator (SVC) using an innovative algorithm based on sequential Monte Carlo simulation and Markov chains. The method employs the equivalent circuit of a SVC and takes the failure rate and repair time of each component as input in order to compute the failure rate and repair time of the whole ...

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 ...

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.
