Energy Hub Scheduling Method with Voltage Stability Considerations

Abstract

Energy Hub is expected to be one of the most effective methods to address the integrated system with multiple energy carriers. In this work, an Energy Hub scheduling method is proposed, which could not only meet various energy load demands but also address the transmission line loss and voltage stability influences. The proposed method is then evaluated by case studies, where the electricity network and thermal network are implemented on the Real Time Digital Simulator (RTDS). The proposed scheduling method is run online with real-time monitoring of the whole system operation status. Results show that the proposed Energy Hub scheduling method is able to reduce the hub operating cost while improving the overall voltage profile.
