Description: These set of programs are written to design a robust power system stabilizer for minimizing the effects of low frequency oscillations in electric power systems. A complete nonlinear model of the power system represented by a single machine connected to an infinite bus is developed in the Simulink environment. A fuzzy Power System Stabilizer is designed using the fuzzy logic toolbox of matlab and its parameters are tuned by a NEural Network controller.

Description: An optimal coordinated control strategy between
generator and VSC HVDC system is proposed in this paper. In
the studied system, a generator is connected with infinite bus
through parallel AC lines and VSC HVDC. The simulation
results show that both the generator and the VSC HVDC system
can be recovered rapidly from minor or severe disturbance, and
the control strategy is robust to the parameter variety of power
system. Simulation are also conducted when the generator and
VSC HVDC system are controlled independently. The simulation
results also show that the system has much better dynamic
responses with the proposed coordinated control strategy than
that with the independent control.

Description: Power system stabilizers (PSS) are now routinely used
in the industry to damp out power system oscillations. In this paper,
real-coded genetic algorithm (RCGA) optimization technique is
applied to design robust power system stabilizer for both singlemachine
infinite-bus (SMIB) and multi-machine power system. The
design problem of the proposed controller is formulated as an
optimization problem and RCGA is employed to search for optimal
controller parameters. By minimizing the time-domain based
objective function, in which the deviation in the oscillatory rotor
speed of the generator is involved stability performance of the
system is improved. The non-linear simulation results are presented
under wide range of operating conditions disturbances at different
locations as well as for various fault clearing sequences to show the
effectiveness and robustness of the proposed controller and their
ability to provide efficient damping of low frequency oscillations.-Power system stabilizers (PSS) are now routinely used
