Design of renewable micro generation monitoring and control application

A multitude of flexible low-cost communication hardware with sufficient performance is available for control of microgeneration and loads in households, but proprietary software is often limited. Robust and simply maintainable solutions are often required in practical applications besides highly-multifunctional programmable logic controllers developed for large industries. Software should be flexible for adoption to control processes and environment. Open-source software is under development and requires more effort. Perspective practical approach to high-quality automation and telemetry, based on open-source software and ultralow component cost is described in this paper. Developed add-ons can be further used for control of micro generation units with power range from 0.5 to 20 kW, such as small-windmills, hydropower stations or different loads in households.
