Power Engineering is the branch of electrical engineering which deals with Generation, Transmission, Distribution, and storage of Energy or Power. It also deals with electrical devices and electric power connected to the systems like Motors, Generators, and Transformers. Power engineering is a network of interconnected components which convert different forms of energy to electrical energy.
Modern power engineering has three main subcomponents: Generation system, Transmission system, and Distribution system. First one deals with the production of electricity. The next one deals with transmitting the power to the load centers. Finally, the power gets distributed to the customers.
