AI in Smart Grid Management Quiz

Answers and explanations appear as you take the quiz.

1. According to the U.S. Energy Information Administration, what can happen if grid supply and demand fall out of balance?
   • Local or widespread blackouts can occur
   • The grid automatically converts to a battery
   • The nominal AC frequency increases permanently
   • All electricity meters stop recording permanently
2. According to NREL’s renewable-integration report, why can wind and solar generation vary over time?
   • Their output is fixed by monthly billing cycles
   • Their output changes with time of day and weather patterns
   • Their output depends only on utility office hours
   • Their output is determined solely by the number of PMUs
3. Which resources does DOE list as examples that may be part of a virtual power plant?
   • Only one large coal plant
   • Only transmission towers and substations
   • Distributed resources such as rooftop solar and battery storage
   • Only residential energy bills
4. Besides their reporting rate, what kind of electrical measurements do PMUs provide for grid monitoring?
   • Only monthly energy bills from customer accounts
   • Only unsynchronized daily temperature averages
   • Only the names of generating stations
   • Time-synchronized voltage and current phasors, with frequency-related estimates
5. When inverter-based resources displace some synchronous generators, which inherent grid response may be reduced?
   • The rotational inertia traditionally supplied by synchronous machines
   • The number of customer meters
   • The speed of light in fiber links
   • The grid’s nominal AC frequency itself
6. Which dimensions does NREL’s dsgrid toolkit use to model electricity demand?
   • Only power-plant name and ownership
   • Time, geography and end uses
   • Only customer names and billing addresses
   • Only market prices without load quantities
7. What does FERC Order 2222 enable for distributed-energy-resource aggregations?
   • Automatic exemption from all utility and market rules
   • Direct sale of electricity to any household without an operator
   • Participation in organized wholesale electricity markets, subject to applicable rules and coordination
   • Replacement of transmission operators by AI
8. At what approximate rate can PMU synchrophasor data be reported, according to DOE’s primer?
   • One measurement every month
   • One measurement per day
   • One measurement every five years
   • 30 or more measurements per second
