Remote Control of Distributed Generation System

The dynamic nature of distributed generation (e.g. from wind) makes to design a control system for wind turbines that utilize wind energy. The design of a wind turbine control system becomes more difficult when the system is operated in grid-connected mode. The major i sues include connection standard, control system complexity, cost and required instrumentation. A low cost control system and its associated instrumentation development is very important for commercial success of a small grid connected inverter based wind turbine. The proposed grid connected inverter based remote control sy tern i a good candidate for distributed generation system such as a small wind turbine. The main purpo e of this research i to present a novel remote power control for a small single phase grid connected inverter using a DC-DC converter and an ADRIOl serial data acquisition card. Before grid connection characteristics of the inverter are programmed for a desired input DC voltage for generating the output electrical power. Input de voltage of the inverter is adjusted by controlling the DC-DC converter. A PC is employed to receive the required output power signal from a di patch center via the Internet. The PC determines the power being fed by the inverter to the grid and uses an ADRl 0 I to control the de-de converter to adju t the power flow to the grid.
