Optimal power flow analysis

Power flow solutions without any optimization techniques can identify a number of abnormal conditions that may present challenges to the planning engineer to resolve. 
Eaton's CYME Optimal Power Flow Analysis module is for advanced system planning studies to optimize system performance, examine cost-efficient operational planning alternatives, articulate system control strategies and rationalize equipment utilization, resulting in better overall system asset management. By carefully selecting the study parameters and constraints, the CYME Optimal Power Flow Analysis module can help to resolve abnormal conditions.

OPTIMAL POWER FLOW ANALYSIS MODULE

FEATURES

The algorithm is based on the nonlinear optimization technique that is coupled with the entire set of system control variables, including generator power dispatch scheduling, transformer taps and phase shifter settings. System equipment constraints are observed, bus voltages and line flows in particular .

The “best possible” values for “higher level set points” are calculated while considering a set of user-specified objective functions and a number of constraints. In this way, it adds intelligence and, consequently, significantly improves the efficiency of power system studies.

The algorithm also includes infeasibility handling through automatic relaxation of immediate binding constraints and comprehensive constraint ranking severity indicators for cases that exhibit convergence difficulty.

The module can assist the planning engineer to solve many of the problems typically found in power systems, including:

  • Scheduling of ancillary services for reactive power and active power
  • Development of system reference scenarios
  • Voltage collapse analysis
  • Transfer capability investigation
  • Location-based marginal cost assessment
  • Implicit penalty function consideration
