Abstract
A solar power conversion system includes a photovoltaic array having photovoltaic modules for generating direct current (DC) power. A power converter in the system converts the DC power to alternating current (AC) power. The AC power is transmitted to the power grid via a transformer coupled between the power converter and the power grid. The transformer is connected to the power grid at the point of common coupling (PCC) and to the power converter at output terminals. A voltage estimation module is configured to estimate a voltage at PCC based on a measured voltage magnitude, a measured real power and a measured reactive power at the output terminals, and a reactance of the transformer. A controller is provided in the system for generating switching command signals for the power converter based on the voltage at PCC.
