Previous Research

Multi-carrier Optimization


Previous: My PhD Research

To develop a scheduling tool for small-

scale systems that contain multiple

energy carriers at district level

(residential) by using the energy hub

approach.

Optimal Usage of Multiple Energy Carriers in Residential

Systems: Unit Scheduling and Power Control

Keywords: multiple energy carriers, micro-cogeneration, optimization, real-time control


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
