  • Integrated and optimized distributed generation and interconnect system controller
    Patent number: 8190299
    Abstract: Systems and methods for designing and controlling distributed generation resources are disclosed. Monolithic or distributed controllers control the power requests sent to each distributed generation resource to achieve optimal efficiency using rule-based and/or fuzzy logic-based control techniques. High-impedance fault (HIF) detection circuitry allows power export to the utility grid in normal operating circumstances, and when an islanding condition is detected, ceases that export within two seconds and prevents further export until the condition is cleared.
