Problems solved by technology

In its basic form it does not contain any time based information and does not provide any information regarding the dynamics of the power system.
Some obstacles to using the PF to implement a power system simulator include the large number of calculations required to performed the PF and the fact that the PF does not contain any information regarding the frequency of the system, a key indicator of power system state.

Abstract

According to one aspect, an apparatus for computing a solution to a power flow problem for an electrical power system comprising a plurality of buses. The apparatus includes (a) at least one processor comprising a plurality of cores; and (b) memory coupled to the at least one processor for storing an admittance matrix for the power system, real power and reactive power for each bus, and an initial complex voltage for each bus; (c) wherein the at least one processor is configured to: (i) perform a Jacobi power flow calculation for each bus to determine the complex voltage for each bus, the Jacobi power flow calculation using the admittance matrix, the real power and reactive power for each bus, and the initial complex voltage for each bus as inputs, wherein at least two Jacobi power flow calculations are performed concurrently on the plurality of cores; (ii) calculate a power mismatch at each bus based on the complex voltages; and (iii) determine whether the Jacobi power flow calculations have converged based on the power mismatch and repeat (i) to (iii) if the Jacobi power flow calculations have not converged.
