A number of electrical switching apparatus electrically connect the output from the microgrid to a grid and electrically disconnect the output from the microgrid from the grid. A microgrid controller detects islanding of the microgrid with respect to the grid, and sends a number of commands to a number of the number of controllers in order to control reactive power injection by a number of the number of power sources. A communication channel is between the microgrid controller and the number of controllers. A number of microgrid loads are powered by the output from the microgrid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system of anti-islanding of a microgrid in a grid-connected microgrid system","description":"A system for detecting islanding of a microgrid includes a number of power sources to output real power and controlled reactive power injection; a number of controllers each controlling one of the num","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9620994","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.
