Full Energy Management of EO-AAC: Toward a Dynamic Equivalence With MMC

Energy management in modular type converters constitutes a key aspect of their operational stability. This paper introduces full energy structure for the Extended Overlap-Alternate Arm Converter (EO-AAC) ensuring both equal distribution across all six stacks and maintaining ripple-free DC current during steady state. The performance control against active power step events is validated by detailed simulations using EMTP-RV software. Moreover, allows EO-AAC to have an equivalent controllability Modular Multilevel (MMC) through only two conducting overlap mode balance. From this observation, it demonstrated that use strategy like virtual capacitor support HVDC system, originally designed MMC, possible. Gathering these controllers leads general conclusion which dynamic equivalence between MMC.
