Abstract

Abstract: Environmental problem is a global problem. Developing clean energy and energy transformation is the best way to solve environmental problems. Building the global energy Internet is conducive in stabilizing renewable energy fluctuations and promoting clean energy development. However, there are still stability problems in high permeability power grid. Motor-Generator Pair (MGP) is proposed and its small signal stability and transient stability are analyzed to solve stability problems. Comparing with thermal power units, the stability of MGP is similar and frequency response characteristic is better. Experiment results also show the stable operation of MGP system. Accroding to results, MGP system can filter harmonics generated by power electronic inverter. Finally, advantages and possible application scenarios of MGP are summarized.

Key words: global energy internet, motor-generator pair, high penetration, power system stability, renewable energy
