Method of Reactive Power and Voltage Optimization Control Based on RTDS

Abstract

Automatic voltage control (AVC) system has been widely used in power systems at home and abroad, with some problems in applications. This paper proposes a closed-loop testing method based on real time digital simulation system (RTDS) and reactive optimization procedures to simulate the actual AVC operation mode, we can obtain an optimal control which is different from the actual AVC system, it can be used as the actual AVC system judgment to evaluate the action effectiveness and the advantages/disadvantages of the actual AVC system compared with optimal results. Finally, the simulation tests show that RTDS-based reactive power and voltage optimization control method is good so that it can be regard as reference to evaluate the control effectiveness of the actual AVC system action.
