Title:
ENERGY MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/170811
Kind Code:
A1
Abstract:
This energy management system (1) is provided with a power generating device (20), a bidirectional DC-DC converter (30) and an inverter (40), which are connected to an HVDC bus (10). The bidirectional DC-DC converter (30) and the inverter (40) each have the same voltage change gain relative to a change in current. If the output power from the inverter (40) or the bidirectional DC-DC converter (30) varies concomitant with a variation in the output current from the power generating device (20), the energy management system (1) adjusts an offset ΔV of the gain characteristic of the bidirectional DC-DC converter (30) relative to the gain characteristic of the inverter (40), and causes the output power from the inverter (40) to converge to a target value. In this way it is possible to provide an energy management system with which the output power of an inverter can be stabilized using simple control.
