Intelligent Solid-State DC Substations – Key Enabling Technologies for Future DC Grids
Abstract:
The change of the electrical supply system to more environmental-friendly energy sources requires the development of a new grid infrastructure. Local or regional balancing between loads and decentralized power generations is found to be a cost effective solution for the future electrical grids which can be realized with direct current (DC) technology. Compared to the classical AC technology, DC grids are also less prone to instabilities and more flexible to control via power-electronic based substations. The tutorial will focus on intelligent dc substations as the key enabler technology for the future flexible DC grids. Latest advances in the topology, control and real-time simulation of the bidirectional isolated DC-DC converters for interconnections of DC grids at different voltage levels as well as AC grids will be reported. Besides, the opportunities and challenges of DC grid protection with hybrid DC circuit breakers or fault-current handling DC-DC converters will be discussed.
