Effective model of MMC for multi-ports VSCHVDC system simulation

Virtual Capacitor Concept for Computationally Efficient and Flexible Real-Time MMC Model

“…Even though all of the operating modes can be emulated by such a combination, a solution, depicted in Fig. 3, ensuring the same performance with two diodes and two controlled voltage sources was proposed in [29]- [32]. In this way, a versatile model of the branch allowing for emulation of both blocked and active states is obtained, providing one with the MMC model depicted in Fig.…”
