Control Requirements

• Analyze and Predict Conditions in the System– Prevent/minimize outages and disturbances– Take corrective actions to maintain integrity of

operation (and improve quality of service)

• Use Communication– Centralized/decentralized methods

• Minimize Human Involvement• Exploit and Integrated Available/Near-Term

Technologies

Milestones: 2011: - Determine impact of high-depth of DER,

EV, and microgrids with respect to: a) technical performance of power

system (50% complete) b) regulatory issues, standards, grid

codes (50% complete) c) protection system 2012: - Develop (linear) dynamic models of

typical power systems, including multiple

microgrids, for control design/analysis (40% completed) - Identify and develop control strategies (50% completed)

www.smart-microgrid.ca

Milestones (continued): 2013: Identify, select, and evaluate

communication requirements and infrastructure for control

(and protection) of microgrids (5% complete) 2014: Evaluate microgrid controls performance (in coordination with the protection system) - Time-domain simulation (15% complete) - Hardware-in-the-loop (20% complete)
