Energy Management System Control and Experiment for Future Home (Parts 1&2)
To enable zero net-energy consumption and optimal power management for future homes or buildings, the dc electric distribution systems (dc nano-grid) finds feasibility and simplicity for integrating multi-type renewable energy sources and energy storage elements. This paper introduces a 380V emulator testbed of 10~15kW, with integration of solar, wind, Li-ion energy storage, plug-in hybrid electric vehicles and smart appliance, to demonstrate the future home. Operation analysis and control laws for each source components are defined. Energy storage management and its control law in dc nano-rid is proposed. System level energy management control strategies in a day/24 hours are examined and discussed with considerations of residential load demand profile, local renewable energy source profile and schedules of electricity rate. Key scenarios of system level experiments are given for verification purposes.
