A robust transient energy function‐based controller for enhancing transient stability of virtual power system

This paper offers non-linear control for enhancing the transient stability in power systems containing a photovoltaic (PV) and doubly fed induction generator (DFIG) by energy function (TEF) method finite-time observers. At first, TEF is utilized to enhance system PV, DFIG, synchronous (SG) constructing hybrid Lyapunov function. Then, derivative terms are estimated with The main contribution of research application technique evaluation consisting SG, DFIG. Another innovation simultaneous DFIG whose uncertain parameters use observer. proposed scheme robust against changes configuration system. In order show capability this scheme, time domain simulations performed on IEEE 9-bus, NEW ENGLAND Standard 39-Bus Using obtained result, some comparisons made back-stepping clarify superiority method. that can properly provide extra damping reduce first-swing fluctuations less time.
