A Comparison between Electric springs and STATCOM For Distributed voltage control

Abstract

The concept of electric spring (ES) has been proposed as of late as a powerful methods for appropriated voltage control. The thought is to control the voltage over the basic (C) loads while permitting the noncritical (NC) impedance-type loads (e.g.,water radiators) to change their energy utilization and in this way add to request side response. In this paper, a correlation is made between dispersed voltage control utilizing ES against the conventional single point control with Static Compensator (STATCOM). For a given scope of supply voltage variety, the aggregate receptive limit required for every alternative to create the desired voltage control at the point of association is thought about. A straight forward contextual investigation with a single ES and STATCOM is presented first to demonstrate that the ES and STATCOM require practically identical receptive energy to accomplish comparable voltage control. Examination between a STATCOM and ES is additionally substantiated through comparative contextual analyses on the IEEE 13-transport test feeder framework and further more on a piece of the dissemination arrange in Sha Lo Wan Bay, Hong Kong. In the two cases, incidentally a gathering of ESs achieves preferred aggregate voltage direction over STATCOM with less general receptive power limit.
