Abstract

A system stores and distributes electric energy. The electric energy includes pulsed energy. The system includes one or more energy sources to store electric energy, one or more converters to distribute first electric energy among the energy sources and distribute second electric energy from the energy sources to one or more entities, interfaces coupled to the one or more energy sources and the one or more converters, and a controller system that performs operations. These operations include receiving a demand for the second electric energy from a particular entity, the demand indicating one or more electric characteristics of the second electric energy and one or more entity characteristics of the particular entity. The operations include, after receiving the demand, controlling the one or more converters to distribute the second electric energy from the one or more energy sources according to the one or more electric characteristics, the one or more entity characteristics, and one or more energy characteristics of the one or more energy sources.
