a novel night-time application of a photovoltaic (PV) solar power farm bidirectional inverter as a battery charger, is presented. It is shown that a combination of PV solar farm and storage batteries can be advantageous in a distribution system having wind farm in close vicinity to the solar farm. Under such a condition, the PV solar farm inverter can regulate the grid voltage (if allowed by the code) by charging/ discharging the batteries as well as provide better asset utilization and return on investments. The PV solar farm inverter is opera ....etc

Abstract
STATCOM can provide fast and efficient reactive power support to maintain power system voltage stability. In the literature, various STATCOM control methods have been discussed including many applications of proportional-integral (PI) controllers. However, these previous works obtain the PI gains via a trial-and-error approach or extensive studies with a tradeoff of performance and applicability. Hence, control parameters for the optimal performance at a given operating point may not be effective at a different operating point. This p ....etc

An Improved Nonlinear STATCOM Control for Electric Arc Furnace Voltage Flicker Mitigation
Abstract
Electric arc furnaces (EAFs) are prevalent in the steel industry to melt iron and scrap steel. EAFs frequently cause large amplitude fluctuations of active and reactive power and are the source of significant power-quality (PQ) disturbances. Static synchronous compensators (STATCOMs) provide a power-electronicbased means of embedded control for reactive power support and PQ improvement. This paper introduces a new nonlinear contr ....etc

Abstract
In this paper, the mathematical model of
STATCOM based on space vector theory is presented. The
voltage equations are transformed into the synchronous rotating
reference frame (dq-axis). The relationship between STATCOM
parameters and stability, transient and steady state
performances are determined. Stability investigation with Routh-
Hurwitz criterion indicates that the STATCOM is a stable
system and the numerical values of resistors, inductors and
capacitors in the STATCOM equivalent circuit have no effect on
stabil ....etc
