Mini-Grid, Micro-Grid and Embedded Network are terminologies that are frequently used but rarely delivered due to technical and financial challenges. To develop a true Mini-Grid or Micro-Grid running solely on renewable energy is the holy grail for many communities, housing developers, and even network operators. The technical challenge though requires the overarching grid voltage and frequency to be generated and maintained as well as supported in the event of storms or weather events causing intermittent or unpredictable renewable generation. The simplest method to create stability is to simply build a large commercial scale PV system with massive house battery, this is often cost prohibitive and the alterative being conventional gas or diesel generation is undesirable. Case study and further technical explanation to be delivered within the presentation.
The embedded network principle can easily be viewed from two ends of the process as there are key benefits to both facing entities of the concept. For end users / consumers, to have networked systems all joined through a common retail trading platform such as sonnenCommunity will share for them the risk and burden of unreliable production, differing user profiles as well as seasonality. The greater grid, also with fluctuating production and demand cycles can be supported by the model via demand response and energy trading on markets such as the FCAS all bringing to the end user / consumer financial and electrical independence. Case study and further technical explanation to be delivered within the presentation.
From the perspective of the network operator, an embedded network of domestic scale storage systems offers great potential benefit too. In the future, private households will can contribute to the stabilization of the power grid by enabling better integration of renewable energies. As such, sonnen and power grid operator TenneT in Germany have partnered to successfully launch a pilot project integrating storage batteries into the power supply system via a blockchain solution.
