tailieunhanh - ENERGY STORAGE IN THE EMERGING ERA OF SMART GRIDS_1

Traditional electrical power systems were essentially based on centralized and fuel consuming power generation plants, where end-users were supplied via unidirectional transmission and distribution grids. The increasing demand for electrical energy and, at the same time, the need for reducing CO2 emissions are now changing these strongholds, and power systems are more and more integrated by “distributed generation” (DG), that is to say small and medium size generator plants managed by end-users (now called “prosumers”, to underline that they are both consumers and producers) and essentially based on renewables | ENERGY STORAGE IN THE EMERGING ERA OF SMART GRIDS Edited by Rosario Carbone Energy Storage in the Emerging Era of Smart Grids Edited by Rosario Carbone Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2011 InTech All chapters are Open Access articles distributed under the Creative Commons Non Commercial Share Alike Attribution license which permits to copy distribute transmit and adapt the work in any medium so long as the original work is properly cited.
