Methods, systems and software products are provided for power system analysis, including a synchronized-measurement-based (also referred to as Phasor Measurement-based) one-shot non-iterative solution to the well-known power flow (or load flow) problem. A set of non-linear equations, quadratic or third-order in form and containing power system parameters and unknowns, are formed and subsequently transformed into a set of linear equations. Subsequently a selected set of variables (or unknowns) are solved for in terms of the remaining variables. A second set of quadratic equations is then defined and used to solve for the selected variables, resulting in a solution set for the non-linear equations. The methodology may be iterative or non-iterative, and may be used for the solution of a number of power system analysis problems to include: AC power flow, AC state estimation, optimal power flow, stability analysis economic dispatch, and unit commitment. |
