摘要：

Increasing demand for energy has been growing very fast. Photovoltaic systems are good solution to provide energy since it is environmentally friendly, and it has zero variable cost. On the other hand, High Voltage Direct Current (HVDC) is gaining importance to transfer power from one grid to another. Modular Multilevel Converter (MMC) has made a great contribution for the development of HVDC since it is modular, scalable and cost-effective. Traditional HVDC system consists of two terminals. However, in the case of an unbalanced condition, HVDC lose stability, and it is a challenge to re-run the system if an MMC is built with high number of capacitors. In this study, large-scale PV plant is used as a backup terminal if a fault occurs on one of the grids, and one of the terminals is lost. The system has been built and tested on Real Time Digital Simulator (RTDS) with the help of FPGA based MMC support unit.
