| Abstract |
Several MMC models are present in the literature. The suitable converter model used depends on thestudies that must be performed. The work presents a simplified electrical equivalent model for the ModularMultilevel Converter (MMC) which can be used for ac power flow and fault studies.The total energy that is stored in the MMC submodules is modelled as an equivalent capacitor. Also,decouples the converter DC link from the equivalent arm capacitors voltages and allows the MMC arm'senergy balance.The proposed electrical model was tested and compared with the existent literature data equivalent model(DEM) under different operating conditions. The mean percentage deviations between the signals retrievedby both models shows the higher deviation less than 1.1\%. Besides very accurate, the presentedmodel reveals to save around 72\% of computational time leading to a faster model. |
