... 80% i.e. a 10kW battery bank becomes 8kW. If the battery is left at low charge for a long time, problems like sulfation occur which reduce battery life, hence battery must always be stored at full state-of-charge. To minimize batteries in parallel and cater to the voltage demand we chose to keep 3 b ...

Distribution management system

In the recent years, utilization of electrical energy increased exponentially and customer requirement and quality definitions of power were changed enormously. As the electric energy became an essential part of the daily life, its optimal usage and reliability became important. Real-time network view and dynamic decisions have become instrumental for optimizing resources and managing demands, thus making a distribution management system which could handle proper work flows, very critical.
