The paper presents the project to Power System Stabilizer applied to the generators of the gas turbines of Combined Cycle Power Station. The project developed used MATLAB software for the stabilizer’s parameters calculation. The calculation was gotten from the linear model based on a machine connected on an infinite-bus. The stabilizers had been used to increase the machine eletromechanic oscil...

In this paper the use of artificial neural network in power system stability is studied. A predictive controller based on two neural networks is designed and tested on a single machine infinite bus system which is used to replace conventional power system stabilizers. They have been used for decades in power system to dampen small amplitude low frequency oscillation in power systems. The increa...

To enhance the inertial response and damping capability during transient events this paper investigates an improved active power control for variable speed wind turbines. The optimized power point tracking (OPPT) controller, which swings the turbine operating point from the maximum power point tracking (MPPT) curve to the virtual inertia control (VIC) curves by the frequency deviation, is propo...

Although the virtual synchronous generator provides a grid-friendly operational mode for power converters, it may also introduce disadvantages similar to traditional such as oscillation in parallel due large inertia. This article proposes an additional damping strategy suppress oscillation. After analyzing relationship between output and angular acceleration, is designed by acceleration control...

This paper presents a parameter modeling to Power System Stabilizers (PSS) using MLP and RBF neural networks. The application of neural networks in PSS aims to improve the dynamic stability of electric power systems by reducing the machine eletromechanic damping oscillation when a disturbance occurs. According to the current plant operating conditions, the PSS parameters are automatically adjus...
