Abstract:
1. A solar power inverter comprising: a direct current (DC) input component configured to receive DC produced by one or more photovoltaic cells; a power generation component configured to generate alternating current (AC) from the DC produced by one or more photovoltaic cells; an AC output component configured to output generated AC, wherein the AC output component is electrically coupleable to an electrical power grid; a data input/output component configured to receive signals indicating electrical power grid synchrophasors, wherein the electrical power grid synchrophasors describe characteristics of AC transmitted by the electrical power grid; a phasor measurement unit configured to generate inverter synchrophasors, wherein the inverter synchrophasors describe characteristics of AC electrically proximate to the AC output component; and a controller coupled to the data input/output component and the phasor measurement unit, wherein the controller is programmed to-receive the electrical power grid synchrophasors from the data input/output component; wherein the correlation coefficient is determined by
