Energy Storage
Grid energy storage also called large-scale energy storage. Large quantities of electrical energy can be stored using pumped hydro or underground compressed air facilities. Smaller quantities of energy can be stored in batteries, flywheels and Superconducting Magnetic Energy Storage (SMES) devices. In Superconducting magnetic energy storage systems a magnetic field is created by direct current passing through a superconducting coil in which resistive losses are negligible and so the energy stored in the magnetic field does not reduce with time. Energy is stored as electrostatic field in capacitor
Energy storage should be available to industry and regulators as its necessary to resolve issues of grid resiliency and reliability. Energy storage should be a well-accepted contributor for realization of smart-grid benefits specifically enabling confident deployment of electric transportation and optimal utilization of demand-side assets. On-Grid Area Renewable increases ratio of renewable generation may cause several issues in the power grid. EV powered by electricity from less or non-fossil energy sources can be made by Off-Grid Area.
We have seen a great response on Energy Storage at Smart Grid conference 2016
