Performance evaluation of power sharing model applied to virtual aggregations

The European Directive 2018/2001 promotes energy communities to enhance renewable energy use and reduce costs, but regulatory barriers limit their widespread implementation. In Italy, the virtual regulatory model allows renewable energy sharing via the public AC grid, avoiding the need for new infrastructure but raising concerns about overload and regulation. This paper introduces an innovative smart microgrid based on low-voltage direct current (LVDC) distribution and a shared control system, the Power Sharing Model (PSM), designed to optimize renewable energy use, mitigate AC grid limitations, and enhance energy management. The integration of a 'Power Alert' device enables real-time monitoring and optimization of self-consumption. Simulation results demonstrate the effectiveness of the PSM in balancing supply and demand, while maximizing the economic and environmental benefits of renewable energy communities. This approach offers a significant step forward in improving energy efficiency, system stability, and the overall sustainability of energy sharing frameworks.
