Impacts of Energy Storage on the Future Power System

AbstractThe electrical energy storage systems serve manyapplications to the power system like economically meeting peakloads, quickly providing spinning reserve, improving powerquality and stability, and maintaining reliability and security.The rapidly increasing integration of renewable energy sourcesinto the grid is driving greater attention towards electrical energystorage systems which are capable of stabilizing the output fromrenewable energy sources. The application of electrical energystorage systems will also defer the installation of newtransmission lines. With the development of advanced energystorage technologies, the electrical energy storage systems aremaking the future power system more reliable, efficient andeconomical. This paper presents various energy storagetechnologies currently used, their applications and the role theyare going to play in the future power system.7 Halama
