Vector control strategy for motor‐generator pair drive inverters in parallel operation

IET Renewable Power Generation, Volume 15, Issue 11, Page 2383-2395, 17 August 2021., 2021
Abstract In view of the weak moment of inertia for power system with high penetration of renewable energy and limited transient voltage support of power electronics, a synchronous motor‐generator pair (MGP) is proposed as a possible solution for renewable energy integration to improve grid stability. In order to realize the large‐scale renewable energy
