Specifies voltage characteristics of public electricity networks under normal conditions. Applies to low, medium, high and extra-high voltage AC networks. Excludes industrial networks and abnormal operating conditions
HVDC transmission uses two converter stations and transmission lines. Overhead lines are common, submarine cables used in some projects. Back-to-back stations connect two AC grids at single point
Power plants convert mechanical energy into electrical energy using turbines. Power plants require fuels like coal, natural gas, wind, or sunlight. Power plants generate electricity far from customer demand
Mains electricity is a general-purpose AC power supply delivered through the grid. Voltage and frequency vary between regions worldwide. Most common combinations are 230V/50Hz and 120V/60Hz
EN 50160 describes voltage characteristics of electricity supplied by public networks. Standard applies to voltage levels: high (36 kV-150 kV), medium (1-36 kV), and low (≤1 kV). Standard defines compatibility levels between network disturbances and equipment immunity
Solar energy isn't always produced at peak usage times. Storage helps solar contribute even when sun isn't shining. Storage smooths out variations in solar energy flow on grid
