Application of PLC as a Gateway in a Network of Smart Power Transducers

The modern control of the electrical power system faces various challenges caused by the introduction of renewable energy sources and rapidly changing loads. Key problem in reaching successful and sustainable control is the smart sensor networks development. The paper presents an approach for development of such network using the possibilities of the programmable logic controllers. The considerations in the organisation of the network and the choice of a PLC as a gateway are discussed. The main options of the proposed software solution are explained.
