The Feed-in Tariff (FiT) has been implemented in Malaysia since 2011 and end in 2016. Net metering will be the next renewable energy implementation mechanism. This paper presents the comparative study of FiT and Net metering for UCSI University North Wing Campus solar photovoltaic system at the economy and energy perspective. A 100kWp solar photovoltaic (PV) system model, real recorded solar radiation...
This paper presents the DC-DC converter model, implementation and simulation using state space modeling approach. Three DC-DC converters including Buck, Boost and Buck-Boost converter are developed using state-space modeling approach and implemented in Simulink. Each converter is modeled based on its circuit topology and its state space matrix are derived in detail. The state space model simulation...
This paper presents a comprehensive set of Simulink models, utilizing SimPowerSystems blockset to simulate various power quality events in distribution system. These models include distribution line fault, induction motor starting and transformer energizing models which are used to simulate various types of voltage sag. Capacitor bank switching model is also presented to simulate voltage transient...
This paper present the tolerance analysis and evaluation of flicker severity Pst short term perceptibility assessment for 1 minute observation time based on IEC61000-4-15 flickermeter standard. The evaluation approach takes a complete range of standard rectangular modulated test waveform set for evaluation of both 10 minutes and the 1 minute observation time. The tolerance is then derived from the...
This paper presents a real time power system harmonic distortion assessment instrument implemented using virtual instrument concept. The measurement hardware consists of measurement probes with signal conditioning circuit connected to a data acquisition module. The data acquisition module is interface to computer through a USB interface. Harmonic distortion assessment algorithm using Fourier transform...
This paper presents a power quality event source directivity detection based on V-I scatter graph. The proposed method is capable to detect both voltage sag and transient power quality event source direction in term of upstream and downstream based on one bus measurement. The V-I scatter graph are plotted based on the RMS voltage and current magnitude at the same instant of time sample onto the voltage...
