As renewable energy penetration rises, integrating it will become a major issue that will necessitate new generating
support infrastructure; an energy storage system is one answer to this problem. Battery technologies, in particular, have a wide
range of energy and power output capabilities, making them perfect for integration. In many regions where renewable energy
generation systems will be implemented, distributed energy storage on distribution grids may be required. When the sun is not
shining or the weather is cloudy, an energy storage system is required for solar photovoltaic systems. For PV applications, a
battery is used as an energy storage system.
