Supervisory Control allows the operator to apply objectives and constraints to achieve an optimal operation of the system. In this mode, recommendations are implemented based on the predefined set of objectives. ETAP utilizes optimal power flow algorithms and user-defined logics to determine the best operating settings for the system. ETAP can advise the operator or automatically control the following equipment:

  • Generators
  • Capacitors
  • Transformer Tap Changers

Volt/Var Optimization is provided with the utilization of Optimal Power Flow (OPF) algorithms. OPF is an intelligent load flow that employs techniques to automatically adjust the power system control settings while simultaneously solving the load flows and optimizing operating conditions within specific constraints. Optimal Power Flow uses state-of-the-art techniques including an interior point method with barrier functions and infeasibility handling to achieve ultimate accuracy and flexibility in solving systems of any size.
