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.
Claims15
A converter device configured to exchange power between a first grid and a second grid, comprising:
- 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,
- 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,
- 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 is optimized according to a predetermined criteria.
A method for exchanging power between a first grid and a second grid via a converter device comprising a first inverter connected to the first grid and a second inverter connected to the second grid, wherein the first inverter and the second inverter are connected to each other via a link circuit, wherein the converter device further comprises a solar generator connected to the link circuit, the method comprising:
- operating the first inverter in a power-regulating operation;
- and
- operating the second inverter in a link-circuit-voltage-regulating operation, wherein a link circuit voltage is regulated by the second inverter to satisfy a predetermined power criteria of the solar generator.
