In-rush current may be controlled by energizing the local load sequentially in stages when a utility grid is connected to the point of common connection. The local loads may also be selectively energized in response to the amount of available local power generating capacity in an islanding situation. A method for controlling a system having local loads and local power sources may include evaluating the power available from local power sources, adaptively controlling the local loads in response to the power available from the local power sources, and operating the local loads and local power sources as an independent system during an islanding event."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Islanded operation of distributed power sources","description":"A method for synchronizing distributed generation power sources during an islanding event may include synchronizing a first one of the islanded local power sources to a master local reference, and syn","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9660451","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
