Abstract
A method for determining a power flow in a distribution network includes the step of determining an admittance matrix for a circuit that includes a floating transformer in an electrical power distribution system. The admittance matrix includes an admittance of a fictitious shunt connected between a non-grounded winding of the floating transformer and ground. The method also includes the step of obtaining real time power measurements from a portion of the electrical power distribution system including the floating load transformer. The method further includes solving the power flow using the admittance matrix and the real time power measurements.
