Historically electric energy has been very important for our prosperity. A key part of the ongoing climate transition is the energy transition, where fossil energy is replaced by electric energy from renewable sources. This supports increased electricity use for electrification of road transports and industrial processes. Wind power and solar PV differ from traditional electricity generation by being weather-driven and thus variable and also by having power electronic grid interfaces. The electric power system is now evolving rapidly to manage the associated challenges to planning and operation. Capacity limits are handled with both traditional grid reinforcement and with automatic control of flexible generation and flexible consumption. The course explains the design and properties of the electric power system during normal operation and during faults, and the impact of renewable generation. Central issues are possible control options during operation and how different types of instability limit power transfer capacity. The contents are lectured and studied through numeric exercises and practical laboratory tests that are preceded by computer simulations. The industrial computerized analysis of large systems is thus introduced, but is combined with calculations by hand to review and interpret computer results.
