ENERGY
Variability in output from wind and solar energy generation can create rapid swings in local and feeder-level voltage , but distributed energy storage can provide fast response to help firm up voltage levels and effectively fill in gaps created by large voltage fluctuations .
Co-locating storage and renewable energy resources gives utilities a particularly effective way of managing unwanted voltage changes , allowing them to maintain grid stability whilst meeting power quality requirements .
Distributed energy storage systems also provide an easily deployed energy resource for utilities , allowing them to ensure renewable energy supplies are available to meet demand . Renewable energy generated when demand is low can then be stored to meet future demand . Energy storage can be deployed in smaller capacity sizes , which can help avoid establishing a completely new plant . Distributed energy storage also supports other useful grid functions . For example : peak shaving , which can provide further savings by reducing the need to maintain conventional generation , and maintaining grid capacity to meet peak demand .
For more information on the latest battery storage technology , come to African Utility Week & Clean Power Conference . The Renewables : Wind & Solar track will have a dedicated session with presentations addressing uses for next generation energy storage on Wednesday 13 May 2015 .
