This section s dedicated to describe the power flow solution methods implemented in OpenDSS. OpenDSS uses three solution methods for solving the power flow problem:


  1. The Normal method (floating-point iterative)


set algorithm=Normal


  1. The Newton method


set algorithm=Newton


  1. NCIM 


set algorithm=NCIM



Figure 1 depicts the general solution algorithm in which the power flow solution goes first, and then the control actions to operate over the latest solution found.
