Cloud Connected Power Inverter

In the Industry 4.0 paradigm, the control of electrical power production and consumption in small energy nodes remains an important objective. The new energy production nodes are usually installed in locations with reduced power requirements. They can produce energy to cover the needs of the consumer and the excess can be pushed in the national power grid system. This paper proposes a scheme to control the balance between produced energy, the locally consumed energy and the energy pushed into the national power grid system, using grid controlled inverters. The inverter connects the local energy source, with the local consumer and also ensures a bidirectional connection to the national power grid system. The inverter can be programmed to satisfy the local consumer power requirements, from the local source or from the national power grid system, and it can also deliver the local excess energy to the national power grid system. The controller is connected with the Internet and is able to send data to an IoT server. This paper presents a solution, along with its supporting technology, to create a network infrastructure based on thinger.io IoT technology. We present this solution for control, monitoring and optimization the electrical power production and consumption for small consumers using the IoT technology. This device can be used in small farm areas where we can monitor and control the balance between energy production and energy consumption from local sources or from the national power grid system. The device can also be used to monitor and control energy flow in remote small industrial plants or agricultural farms.
