Claim:
1. A computer-implemented method of evaluating the state of an electrical grid, comprising: generating a first mathematical model of load flow equations (L) representing an electric power system having an electrical grid in which all voltages are equal to a normal or designed voltage level and there is no energy flow in links of said electrical grid, using a computerized device, transforming said first mathematical model of said load flow equations (L), with said holomorphic embedding, to a second mathematical model comprising a dimensionless equivalent grid model for each node of said electrical grid, using said computerized device, transcribing said first mathematical model and said second mathematical model into software for use in a computer processor adapted to execute said software; using analytical continuation in said computer processor to perform mathematical osculation of said load flow equations at each said node of said electrical grid to calculate voltage at each said node of said electrical grid; and diagnosing an electrical state of said electrical grid by analyzing evolution of s in said sigma index function on a two-dimensional sigma plane using functional dependency of said sigma index function on said holomorphic embedding parameters, using said computerized device.
