Technical and economic assessment for optimal sizing of distributed storage

The introduction of renewable sources poses new challenges to power systems operation. Their impact on distribution networks urges the need of a more flexible grid that can ensure high reliability and power quality as well as operational efficiency. Distributed storage systems may address those emerging challenges by covering operational needs of power, response time and energy. This paper describes a methodology for optimal sizing of distributed storage through technical and economic assessment and storage scheduling optimization. A case study synopsis of voltage regulation and renewable energy time-shift application to LV and MV networks is presented.
