Dynamic programming dp based volt var control
Dynamic Programming (DP) based Volt/VAR Control

  • In each iteration, the control signals to cap-banks (on or off) is generated.

  • Runs power flow and calculates the cost functions for all the possibilities

  • Calculates the incremental benefit with the best solution and performs an iteration if the benefits is less than a preset minimum value.

  • The least cost function solution is the best solution and used to set the optimal IVVC schedule of the cap-banks

  • Typically the cost function is a combination or reduced grid import of VARs, reduced number of voltage violations and reduced losses in the cables
