Abstract :
This paper details a novel energy management technique that is applied to the Alternate Arm Converter (AAC), to ensure converter stability. The control strategy is modeled in Matlab/Simulink and tested on a HVDC active and reactive power operating envelope. To realize the commercial benefits of the AAC, stability in all normal operating conditions is verified. Simulations run over the PQ envelope are shown and the commercial benefits of the new energy management technique assessed.
