Voltage and local stability margin regulation of the receiving node

Regulation methods of the receiving node voltage has been analyzed in the paper. There has been used Thevenin equivalent to develop, simulate and analyze these methods. The paper presents also an on-line method of Thevenin model parameters updating using local phasor measurements. Based on this model influence of the voltage regulation on the local stability margin of the receiving node has been analyzed. Three methods of voltage regulation: transformer tap changing, compensation of reactive power and under voltage load shedding have been examined.
