“…This also implies that the configuration of the energy balancing and power flow control of an MMC can have significant impact on the potential for utilizing internally stored energy and/or power from the dcside to provide inertial response from an MMC HVDC terminal. Thus, previous studies of inertia emulation and control of HVDC terminals as virtual synchronous machines (VSMs), based on 2L VSCs [42] or on MMCs with conventional CCSC [43], will not provide accurate representation of MMCs with closed loop control of the dc-side current and/or the internally stored energy.…”

“…Compared to the implementation presented in [25], the control scheme defined by Fig. 2 a) and b) is completed with circulating current controllers and balancing algorithms for the MMC, based on the implementation presented in [21].…”

“…A Voltage Controlled VSM (VCVSM) is considered based on the implementation from [21]. Most of the general control blocks for the VCVSM are identical to the CCVSM, including the inertia model, the reactive power controller, as well as the circulating current controller and modulation strategies for operating the MMC.…”
