W. El-Khattam, and M. Salama. OSTI.GOV Conference: Distributed generation: Benefits and costs. Distributed generation systems offer even greater resilience and energy independence than grid-connected solar-plus-storage installations. Distributed generation reduces the amount of energy lost during transmission because the electricity is generated near the point of consumption. Small-scale generation is also commonly called distributed generation, embedded generation or decentralised generation. It mainly depends upon the installation and operation of a portfolio of small size, compact, and clean electric power generating units at or near an electrical load (customer). This paper starts from the observation that there is a renewed interest in small-scale electricity generation. We’ve recently explored the many advantages offered by the solar-plus-storage model for commercial and industrial facilities. The purpose of this paper is to quantify this benefit for the simple case of a radial distribution feeder with concentrated load and distributed generator.
