Abstract

The steadily growing share of converter connected distributed generations have been receiving more attention in the last few years because of their high efficiency and superior reliability. This paper presents a novel remote power control method of a small single phase grid connected inverter using a DC-DC converter and an ADR101 serial data acquisition card. Before grid connection characteristics of the inverter are programmed for a desired input DC voltage versus output power. Input dc voltage of the inverter is adjusted by controlling the DC-DC converter. A PC receives the required output power signal from a dispatch center via the Internet. The PC measures the power being fed by the inverter to the grid and uses an ADR101 to control the DC-DC converter to adjust the power flow to the grid. This paper presents the control scheme and test results of a 250 W grid connected inverter.
