Description: In this paper Static Synchronous Compensator
(STATCOM) is used for voltage stability and the
compensation of reactive power. The STATCOM contains an
Insulated Gate Bipolar Transistor (IGBT) based voltage
source converter for voltage control and reactive power
compensation. The STATCOM is used to control the reactive
power with the voltage source converter in combination with a
DC voltage source. The values of the DC link capacitor and
battery source were optimized using the Genetic Algorithm
technique and the simulations results for the same were
observed under the inductive as well as capacitive load
conditions. The comparison of voltage compensation for
various conditions show that the performance of STATCOM
tuned with GA was the best and closest to the nominal value of
voltage. The simulation is done in MATLAB for STATCOM
and Voltage Source Converter (VSC). Platform: |

Description: The fast control capability of the VSC-HVDC and
the process of area mode oscillations are analyzed. An auxiliary
fuzzy logic controller designed in Matlab for the Voltage Source
Converter based HVDC transmission system, VSC-HVDC, to
improve the stability of the AC/ DC system is designed to enhance
stability by increasing the deceleration energy of oscillation.
Simulation results on the IEEE 4-generator AC/DC power
systems have shown that the controller can enhance the dynamic
stability of interconnected power systems effectively and is robust
to the variation of system operating conditions and oscillation
modes. Platform: |

Description: This paper deals with the design and implementation of
a multilevel voltage source converter based static synchronous
compensator (STATCOM) employing an effective modulation
control technique simulated in a MATLAB Simulink
environment. The main objective of this paper is to maintain the
voltage stability by compensating the reactive power in the power
system. Hence, a new efficient control strategy is proposed, in
order to reduce the voltage fluctuations like sag and swell
conditions and also to isolate current and voltage harmonics in
the transmission system. The multilevel STATCOM which can be
used at the point of common coupling (PC C), for improving
power quality is modelled and simulated using proposed control
strategy and the performance is compared by applying it to an
llOkv line with and without STATCOM. Relative Harmonic
analysis is also discussed in this paper based on the total
harmonic distortion (THD) calculations. Platform: |

Description: This paper investigates the effects of Static Var
Compensator (SVC) on voltage stability of a power system. This
paper will discuss and demonstrate how SVC has successfully
been applied to power system for effectively regulating system
voltage. One of the major reasons for installing a SVC is to
improve dynamic voltage control and thus increase system load
ability. This paper presents modeling and simulation of SVC in
MATLAB/Simulink. In this paper A SVC is used to regulate
voltage in a power system. When system voltage is low the SVC
generates reactive power (SVC capacitive). When system
voltage is high it absorbs reactive power (SVC inductive). The
SVC is rated +100 Mvar capacitive and 50 Mvar inductive. The
SVC more effectively enhance the voltage stability and increase
transmission capacity in a power system. Platform: |

Description: The objective is to present a nonlinear approach to design a suitable controller system for the photovoltaic (PV) single-phase grid-connected system. The system structure includes a PV generator, Boost converter, and DC-AC inverter coupled to grid network. A backstepping controller is developed to extract maximum point power tracking (MPPT), to regulate the DC bus voltage, and to generate a sinusoidal current into the grid in phase with grid voltage in order to achieve unity power factor. The stability of the control algorithm is demonstrated by tools of Lyapunov analysis. Simulations show that the proposed controller system completely accomplishes listed aims even under atmospheric conditions variation. Theperformance of the proposed controller has been validated by numerical simulation in MATLAB SIMULINK(The objective is to present a nonlinear approach to design a suitable controller system for the photovoltaic (PV) single-phase grid-connected system.
