Study on IoT based SCADA system for rooftop solar power systems in Vietnam

Rooftop solar power projects in Vietnam are increasingly popular and have certain impacts on the distribution power grid. Thus, solar panel systems are designed and built with many scales and features that are increasingly flexible, easy to install as well as in use. Moreover, the management and operation of distribution power grids with solar power stations also need to be improved so that local power companies can monitor the operation current status of the system. In this study, an Internet of Things (IoT) - based Supervisory control and data acquisition (SCADA) system is proposed to serve the management and supervision of the operation of rooftop solar power stations on the typical distribution grid of Ha Tinh Power Company, Vietnam. The test research results show that the SCADA – IoT system operates stably, data is sent to the server fully and there are no signs of loss, except in cases of WiFi signal loss or unstable 4G network signal due to the provider. Therefore, Ha Tinh Power Company can control the operation of all rooftop solar power systems and make appropriate distribution grid operation strategies.
