The global utility industry in recent years has seen significant build-out of customer-owned distributed generation (DG) in their electric network. This unreliable and non-dispatchable generation is primarily in the form of small, rooftop PV solar arrays. The consequence is that many utilities are struggling with crew safety, localized grid stability, and generation dispatch due to high density solar on distribution circuits.Grid companies have already identified the impact of intermittency issues with high density solar and have also identified need for smart inverters but, they have only realized a small subset of what could be gained by integrating distributed Smart Inverters with Integrated Storage (SIIS) technology. Coupled with local demand response, SIIS enables ultra-fast autonomous response times, eliminating the need for complex central command-and-control DMS. SIIS has further advantages of reduced environmental impact, sustainable operations, and economic advantages over utility large scale solar and storage.This paper will discuss the various operating concerns facing utilities and explain how SIIS integrated with PI situational awareness addresses these issues. Among the issues addressed are: DG variability, voltage fluctuation, high current management, frequency excursion control, VAR control, and spinning reserve generation mitigation.
