This paper prioritizes the different passive parameters on the basis of performance capability in selecting the parameters for intelligent islanding detection techniques. The responses of 16 different passive parameters are analyzed under all possible islanding and non-islanding conditions. As a result of this, it has been found that rate of change of frequency over reactive power shows the highest capability to distinguish islanding from other events of similar signatures followed by rate of change of reactive power and rate of change of power.

Modular Multi-level Converters (MMCs) are considered as one of the promising multilevel converter topologies specially in high voltage applications such as HVDC transmission systems. The idea behmd MMC is to use floating capacitors as a voltage sources along with a switchmg circuit (chopper cell) to form what is called “submodules”. These submodules are inserted or bypassed according to the required output voltage level. To ensure a stable operation, submodule capacitor voltages should be kept m the same level, total converter energy should be uniformly distributed between the three phases. This can be achieved by controlling the current that circulates between the three phases. In this paper a grid connected three phase MMC is considered. An analytical study has been done, operating principles, mathematical model and control system have been described. Also, the system performance has been verified usmg shnulation with Matiab-Shnulink.

This paper presents an investigation on active components in nature based dyes as well as the electrical characteristic of both dyes from hibiscus and bougainvillea. Experiment was conducted using the Fourier transform infrared (FT-IR) spectroscopy to investigate the working components in the dyes pigment as well as solar simulator to simulate 1 sun radiance for the purpose of electrical data collection. Fabrication of the DSSC was done using Dr. Blade's method and as well as by using the carbon counter electrode. FT-IR shows that H-DI and H-Etha has important component such as the carboxyl and hydroxyl group which can bind to TiO2 to produce electron generation. As for the B-DI, carbonyl component as well as hydroxyl components was observe as well. In terms of its electrical performance, hibiscus pigment extract from di-water solvent exhibits high photoelectrical characteristic compare to B-DI, though the margin is small. Overall experiment shows that both dyes have potential in being used as dye as an alternative to their synthetic partner.

This paper presents a simple solution to the variable switching frequency and high torque ripple which encountered by hysteresis-based Direct Torque Control (DTC) drive. To solve this two major problems, a new carried-based torque controller is introduced to replace the previous hysteresis torque controller which operate by comparing torque error with the triangular waveform. Since the dual-inverter supplied drive is implemented, an optimal switching strategy scheme is adopted for ensuring the most appropriate amplitude of voltage vectors is selected according to machine operation condition. As a result, the torque error become easier to be control inside triangular waveform since the rate change of torque or torque slope become lesser then the slope of triangular waveform. By combining this simple carrier-based torque controller with optimal switching strategy scheme, the DTC performances able to be improved further by providing constant switching frequency as well as torque ripple reduction. Then, all this improvement offered by proposed schemes are validated through the experimental results.

Petroleum-based mineral oils are insulating media that are typically used in the industry, particularly for high voltage (HV) applications. In recent years, however, there is growing interest among researchers to formulate novel dielectric liquids in replacement of petroleum-based mineral oils since mineral oils are non-biodegradable and highly flammable. In addition, the dielectric performance of mineral oils is somewhat limited and therefore, there is a need to develop alternative insulation oils with superior dielectric performance in order to fulfil the demanding requirements of dielectric liquids. One of the promising substitutes for mineral oils is ester oils. In this regard, this research investigates the bridging phenomenon in two types of ester oils with different values of viscosity, i.e. natural and synthetic esters under the influence of direct current (DC) electric field. Three different sizes of contaminants are used, i.e. 100, 300 and 500 μm. The results show that both the size of particles and oil viscosity play important roles in the formation of cellulose bridge and breakdown behaviour.

The increment rate of gross domestic product (GDP) and electricity consumption had been consistent until the mid-1990s where Malaysia experience a slump in GDP but our electricity consumption continued to increase until now. To reduce the energy consumption, we need to perform an energy analysis based on factors that affect the energy consumption and trends of data from two different commercial buildings. There are five main factors which are equipment's, outside temperature, building structure, operating hour and people. Among these factors, temperature will be considered to analyse energy consumption in two different commercial buildings in Malaysia. The motivation to conduct this analysis is to establish the benchmarking of the energy efficiency of the commercial buildings since it has not established yet in Malaysia. In this paper, Multilayer Perceptron (MLP) based on Artificial Neural Networks (ANN) has been implemented for energy efficiency analysis. The results of this analysis showed that the energy prediction by using artificial neural network is better than traditional method used by industry which is linear regression where linear regression show the highest error square for both buildings which is 30491.23 for Skywarth and 91738.31 for Skymage building. By comparing the results of two different buildings, we can conclude that outside temperature plays an important role in determining energy consumption of commercialize building. For future study, an advanced method such as k-Nearest Neighbor or Support Vector Machine can be used to predict the energy consumption, so we could obtain better prediction results.

Studies on photovoltaic (PV) arrays have demonstrated that some arrays suffer from mismatch power losses even under uniform illumination. This mismatch power loss that is attributed to the inequality of characteristic parameters between a PV array's modules is conventionally addressed by sorting techniques — which stands for sorting PV modules in an array by one of their characteristic parameters such as Isc, IMPP or PMPP-Another recently suggested method to address this problem is arranging modules by genetic algorithm (GA). This paper applies this new technique to three PV arrays with relatively high mismatch losses. I-V curves for each array's modules are measured under different levels of radiation to provide a precise model. This precise modeling is used to run an annual simulation of energy yield and mismatch losses. Simulations carried out in this study show that a proper arrangement of modules in arrays decreases the mismatch losses and increases annual energy output more than what is gained by sorting techniques.

The common insulating oil used in oil-filled transformer applications is mineral oil. In recent years, significant attention has been paid to alternative insulating fluids such as synthetic and natural ester liquids. The natural ester liquid is considered to be the best substitute of mineral oil in future. In order to apply natural ester liquid in transformers safely, it is important to have detailed information on its dielectric properties and its performance should be proven to be comparatively at par with mineral oil. This paper mainly focuses on a comparative study of ac breakdown voltage, dielectric constant, dissipation factor (tan δ) and resistivity of five different types of natural ester liquid under a variation of temperature. The natural ester liquids used in this experiment are rice bran oil, palm oil, corn oil, sunflower oil and canola oil. Based on the results, the dielectric constant and resistivity of all types of natural ester oil decreased with the increase in temperature. However, the dissipation factor properties in this experiment increased with the increase in temperature. In general, among all types of natural ester oil, the canola-based ester oil has the best potential to replace the current transformer oil due to its good dielectric properties as shown in this paper.

Harmonic that occurs in electrical power distribution system can disrupt and even decrease the quality of power services, so that reduction or removal of those harmonic are needed to be done. Wavelet transformation can give resolution of both frequency and time at the same time, this capability is often called Multi Resolution Analysis (MRA). Wavelet transform is applied in order to remove those harmonic voltages. Simulation has been done using Matlab. The result showed that the wavelet transformation is very effective to reduce harmonic voltages up to seventh harmonic.

Power system operation became a challenging with the integration of variable and uncertain Renewable Energy Sources (RES) generation. The operational flexibility describes the technical ability of the power system to respond to the net-load within a controllable power at a certain time to accommodate the RES power output. The main objective of this paper is to analyse and evaluate the impact of the variation of ramping and capacity weights on the flexibility quantification of the IEEE RTS-96 test system. This paper contributes to the up-rising field of flexibility by providing a precise analysis of a deterministic metric and weights variation to assets the available flexibility from the individual generator and as well as when aggregated within the power system. The analysis is executed using a deterministic metric with an iterative variation of both ramping and capacity weights simultaneously to quantify the technical flexibility of the overall system and each different technology of the test system. The results demonstrate that the increment of the capacity weight has more influence on the individual generators flexibility and the overall system flexibility as well. The incremental rate of flexibility is not linear for all the units at the test system. This metric is useful for the power system operators and planners who requires simple, fast and offline metric to quantify the technical flexibility of the power system.
