Production, transmisson and distribution of electrical energy

Planning of electrical power system is a core theme of the research done by the Institute for Electrical Power systems. Long term grid expansion planning is covered as well as short term operational planning. With help of powerful grid analysis tools, load flow analysis, short circuit analysis, dynamic stability and reliability analysis is performed. An important aspect is the integration of generation (classical synchronous connection as well as inverter based generation) into transmission and distribution systems. Our studies cover normal operation and abnormal cases (faults, grid restoration, special switching configurations).
