Grid connected energy storage system to profit from net-metering and variable rate electricity

This article analyses an application of a grid connected battery-based storage system to profit from net-metering and variable rate electricity available in some Canadian provinces. It is possible for customers to manage their energy consumption in response to energy prices variation over a day by integrating an energy storage system in a home. In the present analysis a prototype of the battery based energy storage system has been designed and implemented. A control algorithm has been proposed to investigate the impacts of different charging and discharging scenarios. The proposed control algorithm is able to control the battery energy system as required in a typical home. Sizing and cost calculations indicate that such a system can profit from variable rate electricity. The outcome of this case study can be extended and used by residents who are interested to generate profit from variable rate electricity.
