Power Flow Analysis (2.5): Methods Based on Newton-Raphson (FDPF and DCPF)

In this video we discuss methods based on Newton-Raphson which makes the calculation of the Jacobian matrix more efficient - namely, the fast decoupled power flow (FDPF) method and the direct current power flow (DCPF) method. These methods make assumptions on the phase angles and magnitudes of node voltage and admittance and then approximate the Jacobian matrix to a simpler form that allows the division of the original power flow problem into smaller subproblems. Because both FDPF and DCPF are still iterative methods (their solution procedures are still the same as Newton-Raphson, just that they use approximated versions of the Jacobian matrix), they still do not solve the non-univocality issue of Newton-Raphson method - i.e. these solvers may still yield a low voltage solution, or they can still diverge even when a high voltage solution exists. In addition, the assumptions in FDPD and DCPF are only justified when modeling High voltage lines of the transmission network, under normal operation conditions with large safety margins.
