Coordination of Reactive Power Sources to Correct Bus Voltage Violations inan AC-DC System

The paper presents a formulation for coordinating all controll-able reactive power sources, including the DC converters of a multiterminal DC system, to correct bus voltage violations. Based on the formulation, an algorithm using Linear Programming solution technique has been developed. The effectiveness of this algorithm to correct bus voltage violations in a 30 bus, 5 DC terminal AC-DC system under heavy and light load conditions is demonstrated.
