High reliable and advanced cost effective solar production with stable organization

When connecting to the grid isolation plays a key factor in selection of power topology and system design. Isolation requirements depend on the type of PV Panel used and the local grid codes. Isolation can be at the grid connection stage, which uses low frequency transformer. In this case both the boost and the inverter stages may be controlled using a single microcontroller. However, low frequency transformers are heavy, bulky and lossy. Therefore cannot be used for low power PV inverters. Here, this project implements PV inverter topology with isolation at high frequency. This project discusses the design of a smart grid-enabled renewable energy node using a heterogeneous dual core microcontroller. Real-time control of extracting the energy from the renewable source is done on one core and the Ethernet server is run on the other core. Hardware design for the energy node to extract maximum power from the solar panel is discussed along with communication interface. Software design and integration challenges for control and communication are presented and the solution using dual core microcontroller illustrated.
