Comprehensive P-V Curve Voltage Stability Assessment

Overview
The P-V assessment tool can compute voltage at all buses in a loadpocket for any contingency, can compute the (Pmax, Vmax) for up to 20,000 P-V curves. Allows one to focus on one loading level and each transfer limit level for each load pocket after only single contingencies, after only double contingencies, or after only triple contingencies for a specific base case to assess security at the base, N-1, and N-2 security levels.

More Comprehensive
  • Reduce manpower and costs of computing P-V curve assessments for a system composed of several areas with several contingencies associated with each area where all contingencies solve and are close to voltage instability
  • Simulates tens of thousands of P-V curves per hour including different areas, contingencies, critical buses, power factor changes, loading patterns, and transfer patterns
  • Allow one to focus on one loading level and each transfer limit level for each load pocket after only single contingencies, after only double contingencies, or after no contingency for a specific base case or for all three cases
  • Increase the comprehensiveness of the assessment by focusing on several loadpockets and areas simultaneously in one batch operation and producing separate reports and assessments for each
Structural
  • Perform P-V curve assessments for one or more loadpockets with contingencies that are unsolved but made secure via some design option, operation planning option, or by Intelliconís Postured Unit Commitment, Postured Capacitor Protection, or Postured Load Shedding Control
  • Organizes curve output in structured, intuitive format making analyzing the vast amounts of data seamless and easy
  • Can utilize customer specified or Intellicon determined areas and loadpockets
Diagnostic
  • Find minimum operating limits on each interface or boundary
  • Can plot P-V curves or assess P-V curve margins using criteria provided by the customer
