Storage simulations for distribution system analysis

Storage is being proposed to solve many issues on distribution networks and distribution planners need tools to assess its impact on capacity, reliability, and power quality. Accurate analysis requires sequential-time simulation. This paper describes three types of storage simulations on distribution systems for three different time frames: capacity evaluations in 15-min intervals; renewable generation smoothing in 1-min intervals; and electromechanical dynamics analysis in intervals ranging from seconds down to microseconds. The illustrations come from recent research.
