Design considerations for distributed micro-storage systems in residential applications

This paper presents some design considerations for distributed micro-storage systems in residential applications. In this paper, the term “micro-storage” refers to small residential energy storage units with a capacity of few kilowatt-hours. Generally, energy storage systems enhance the performance of distributed renewable generation systems and increase the efficiency of the entire power system. Energy storage allows for leveling the load, shaving peak demands, and furthermore, transacting power with the utility grid. Different micro-storage system architectures as well as analysis of system sizing are discussed in the paper. In addition, different energy storage technologies, inverter design considerations, and smart grid integration issues will be also presented.
