Recent: Zero-Watt Project
• Sponsor: Croon Elektrotechniek
• Objective: To minimize the exchange of power between the grid and a real
building that contains several micro-generation units and a local energy
management system. The building has several urban wind turbines, 130 PV
arrays, a CHP of 5,5 kWe and a battery system of 30 batteries in series.
• Partners: Croon Elektrotechniek, Alphen
• Keywords: autonomous networks, integration of renewable energy, storage
optimization, multi-carrier systems
