For a VSC-HVDC transmission system based on a hybrid topology converter of full-bridge and half-bridge, a kind of virtual synchronous generator (VSG) control strategy which can be applied to modular multilevel converter (MMC) grid-connected structure was researched and proposed.
First, based on the conventional VSG control strategy, the energy stored in the equivalent capacitor of MMC power module was used to imitate the rotor inertia of synchronous generator.
The characteristics of generator can be simulated during transient frequency fluctuations and it can help relieve the power fluctuations.
Secondly, with respect to the structural characteristics of the direct grid connection through the reactor on the AC side of the MMC, which is unlike the microgrid inverter, there are no additional filter capacitors.
So, the existing commonly used VSG control strategy of the microgrid inverter and double-closed-loop structure composed of filter capacitor voltage and AC current cannot be directly applied.
For this, a method where the given values of inner current loop are calculated by grid impedance matrix was used.
So, a double-closed-loop control structure composed of a power outer loop based on VSG control and a current inner loop is obtained.
It can effectively improve the current control capability during the transient process.
Finally, a hybrid MMC simulation model was built based on PSCAD to verify the correctness and effectiveness of the proposed methods.
