摘      要：This paper proposes a control strategy for interface of distributed energy sources into the weak grid system with a focus on the energy and ancillary services.A novel controller has been designed and implemented to tackle the challenges of coupling terms in the LCL filter,the transient behavior under sudden changes,and the voltage support under fault condition using the feedback linearization *** controller proposed has been implemented on the PV system connected with the weak grid using the LCL filter and the performance of the controller has been verified using Matlab/Simulink through simulation under different *** results of the controller proposed have been compared with the conventional PI dual loop *** simulation results obtained demonstrate the effectiveness and simplicity of the controller design strategy.
