Data exchange between distributed energy resources and active customers for stable grid and energy saving by efficient storage

The increasing share of renewable energy sources in relation to the total generated energy increases the requirements for the flexibility of energy systems. This paper explores some methods and technologies for building an interoperable interface between the IoT devices related to energy consumers and producers in order to allow reliable operation and savings based on demand side management and energy storage. In the particular showcase the IoT devices use public data from the distributes service operator or the energy exchange to reduce the electrical energy cost for the customer, but also to reduce the peaks in the generation profile.
