The generation, delivery and consumption of electricity are realized in an integrated system which is called electric power system or power system. An electric power system consists of three principal divisions: power generation, power transmission system, and power distribution systems. Lecture 1 All the electricity the consumers take from the power system is generated in a power plant, or called power station, of some kind. Power generation is the first stage of the whole progress of the utilization of electric energy. Transmission systems are the connecting links between the generation plants and the distribution systems and lead to other power systems over interconnections. A distribution system connects all the individual loads to the transmission lines at the substations which perform voltage transformation and switching functions. Small generating plants located near the load are often connected to the subtransmission or distribution system directly. Lecture 1 Interconnection to neighboring power systems are usually formed at the transmission system level. The overall system thus consists of multiple generating sources and several layers of transmission networks. This provides a high d
