Abstract
Various embodiments are provided for performing a power flow analysis using a set of multi-phase element-based line-wise power flow equations in a multi-phase AC-DC power system. In at least some embodiment, the set of multi-phase element-based line-wise power flow equations is solved using a Newton-Raphson method.
Claims14
A method for conducting a power flow analysis for a multi-phase AC-DC power system, the multi-phase power system comprising at least one multi-phase AC branch having a first end coupled to a first bus and a second end coupled to a second bus, at least one multi-phase AC-DC controllable converter and at least one DC branch having a first end coupled to a first bus and a second end coupled to a second bus, the method being implemented by at least one server comprising at least one processor, the method comprising:
- initializing values for a solution vector (U);
- modelling the multi-phase AC-DC power system using a set of muti-phase element-based line-wise power flow equations that are functions of the solution vector (FT(U));
- solving the set of muti-phase element-based line-wise power flow equations (FT(U)) using a numerical technique to obtain a line-wise solution vector.
