Converter apparatus and operating method

Abstract

A converter device configured to exchange power between a first grid and a second grid, including a first inverter configured to connect on an AC side thereof to the first grid, and connected on a DC side thereof to a link circuit of the converter device, and a second inverter configured to connect on an AC side thereof to the second grid, and connected on a DC side thereof to the link circuit. The converter device also includes a solar generator connected to the link circuit, a first controller operably coupled to the first inverter and configured to set a specified converter power of the first inverter, and a second controller operably coupled to the second inverter and configured to set a voltage of the link circuit such that a power of the solar generator optimized according to a predetermined criteria.
