Capacitor banks are commonly connected to the power system to enhance its reliability by providing voltage support, improving power factor, and increasing the system capacity. They are usually switched in and out of the system according to the amount of connected load. This paper analyzes the measurement data of a distribution utility with shunt capacitor banks located downstream from the power quality...
This paper develops an integrated multi-domain simulation tool for distribution systems designed specifically for applications in wind power analysis. The proposed tool consists of steady-state, electromechanical transient, and electromagnetic transient models of voltage sources, transmission lines, transformers, capacitor banks, fixed-speed wind turbines (FSWTs), and wide-slip wind turbines (WSWTs)...
Aiming at the problem of circulating current in MMCs, a novel circulating current suppressing controller (CCSC) is proposed based on the internal-model principle in stationary αβ0 frame in dc-loop control, with the proportional-resonant (PR) regulator adopted. Compared with the existing one, the proposed CCSC seems better, since it does not need the massive amount of computation for estimating the...
