Technical requirements and field experiences with MV DC switching equipment
Today's power grids are generally powered by AC electricity. Energy flow was historically from generation in power plants, through transmission and distribution, to the consumer. Recently, this structure has begun changing through the addition of generation sites distributed throughout the transmission and distribution systems. Beyond the baseline demand for safe operation under load and fault conditions, the additional generation connections stress the physical boundaries of AC networks. These changes are influencing the capacity of the network, its short circuit level, and the level of control that is capable with the tools and technology available today.
