A two‐level hybrid control strategy to augment transient stability and tracking accuracy of hybrid microgrid coupled with industrial loads

The hybrid microgrid (HMG) is an arrangement for empowering the society by using renewable energy sources (RESs) connected with common DC bus terminal. effective operation of HMG relies on transient response as well stability system state that may change due to stochastic behavior RESs and industrial loads. This work motivated develop a two-level decentralized control strategy consisting non-linear linear scheme augment tracking performance HMG. Firstly, partial feedback linearization framework combined PI regulator (PFLC-PI) designed enhancement bus. Secondly, unified controller (UC) developed guarantee constant load voltages over loads through load-side inverter. UC effectiveness measured varying parameters associated single- three-phase networks. obtained results are then compared existing controllers augmented proposed controller. Additionally, external parametric uncertainty intentionally added single-phase network dynamics studied ensure robustness
