Multi-RCAT modem for Small-Scale PV Systems and Renewable Energy Communities

Abstract

In recent years, there has been a significant trend in the energy sector to build small-scale photovoltaic plants (PVPs). Such PV plants are a good tool to accelerate the drive towards zero-emission infrastructure in Europe. At the same time, however, they bring a lot of pressure to adapt the existing power grid to their unique requirements. This paper discusses the key features and typical communication technologies in Smart Grid systems, which can be utilized by small-scale PVPs. Based on the discussed features and challenges of small-scale PVPs, a modem prototype unit for reliable and secure communication is introduced. The proposed modem utilizes multiple wired and wireless technologies to ensure the best possible scalability and adaptability for most scenarios that may occur in Smart Grid communication scenarios.
