Improve Electrical Grid Effectiveness (310)
Problem: Need methods that allow secure operation of the electrical grid with reduced (minimal) reserve margins
Project Activity Scope (from Technical Overview Chart): Mechanisms through Instruments
PNNL Solution:
- Generation or load variations can cause line frequency excursions and grid instability
- Distributed load control can help minimize frequency excursions
- Identify appliances available for load shedding without reducing user benefits
- Estimate value of load response to power grid and customer impact
- May deliver up to 100% of needed power grid frequency control
Capabilities Employed to Meet Client Needs: Electrical power system dynamics and stability analysis including transient stability analysis; power system modeling and simulation; application of control theory; voltage stability assessment; small signal stability analysis; electrical power system dynamics analysis; load modeling; model validation; software development; energy end-use metering; electric power frequency stability and control; power system economics; energy efficient process control.
