Fixed Point Method

In words, given a set of nodal power injections, a guess at nodal voltages is made initially, and nodal current injections are calculated based on latest voltages and power injections. Then, a set of voltages is calculated using currents. The process is repeated until values of voltages remain unchanged according to a pre‐defined criteria. This procedure is called fixed point method in OpenDSS.

It seems that power injections in the previous snapshot are still required.
