Voltage stability assessment using PMUs and STATCOM

<p class="Abstract">Since the previous few decades, researchers and utilities have been extremely concerned about voltage instability because to numerous instances of system blackouts caused by that recorded in various regions world. With development synchro phasor technology, it appears conceivable track manage system's stability real time. This study suggests using measuring units (PMUs) placed strategically monitor margin online regulate a static synchronous compensator (STATCOM). According minimum reactive power loanability for most line outages, STATCOM has installed at critical bus. Based on difference between bus its reference value, supplies into PMU measurements are used determine voltages regular intervals, is then added as necessary. The increased brought injecting continuously checked. simulations performed IEEE 14-bus New England 39-bus system, effectiveness suggested approach monitoring management (VSM) proven.</p>
