This paper presents the influence of non-conventional sources like central station solar photovoltaic model and wind plant model in multi-machine power system for transient stability. Modified four-generator system is studied by replacing one of the conventional synchronous generators with solar photovoltaic and wind generator model. The performance is compared with the classical four-generator system...
The paper proposes a Frozen Riccati Equation based approach for the construction of Lyapunov function to present a control law for the terminal voltage regulation in a post-fault transiently stable situation in a multi-machine power system. The test system is modelled in nonlinear singularly perturbed manner. Without linearization or complex solution of Hamiltonian-Jacobian Bellman equation, the gain...
The importance of parasitic parameters in the study of a dynamical system is brought out in this work. The neglect of these parameters in the context of invariant manifolds for a multi machine power system for transient stability is studied. Singular perturbation approach is used for the calculation of critical clearing time of a large disturbance fault using equilibrium and invariant manifolds. It...
