The charging of plug-in electric vehicle (PEV) imposes an additional burden on the utility grid, particularly during the (day) peak hours. This burden is normally controlled by shifting PEV charging to the grid off-peak hours. This shifting not only reduces the autonomy of anytime charging but also creates the uncertainty about the charging price every hour. To mitigate this problem, this paper proposes an energy management scheme (EMS) for the charging station that combines the photovoltaic (PV) and energy storage unit (ESU) with the grid. The models for PV power, ESU, PEV demand and grid electricity price are developed as the components of EMS. The scheme is capable of providing interruption-less charging during day-time. Moreover, the EMS has the capability to charge PEV with constant per unit price at and below the level of solar grid parity. The additional feature of EMS is that it can fulfill charging demand of each PEV within one hour at a lower price than standard grid (SG) charging while reducing the extra burden on the grid. The idea to reduce the economic loss of charging station due to cheaper and constant price charging is the involvement of valley-filling operation by both ESU and PEV along with selling the surplus PV energy to the grid. The EMS algorithm comprises of rule-based strategies. To determine the effectiveness of the scheme, numerous charging scenarios are simulated using Matlab. The initial results indicate that the charging through proposed scheme is much cheaper than the charging by conventional SG scheme. Moreover, it has shown to reduce the considerable amount of EV charging burden from the grid. It is envisaged that this is the first effort to propose constant price PEV charging and it will provide an exciting prospect in the field of PEV charging using renewable energy sources.

Harmonics and voltage flicker are increasing dramatically in power system due to wide use of non-linear loads. Specifically, voltage flicker is detected due to fluctuation of Root-Means-Square (rms) value. Meanwhile, harmonics with certain components may lead to fluctuation of rms value too. Then, harmonic components may give significant impact on voltage flicker measurement. Therefore, this paper points out a worthwhile research gap regarding investigation of harmonic components on voltage flicker measurement. For further validation of the work, various harmonic orders and percentage injections generated from programmable AC source are analyzed by flickermeter (Fluke power analyzer 435 series II). From the findings, it is confirmed that second order harmonic component gives the most significant impact on voltage flicker measurement. Most importantly, a new linear expression is formed to clearly describe relationship between Short Term Perceptibility (Pst) and percentage of second harmonic component.

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.

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.

This paper presents the results of an exploratory study aimed at investigating the impacts of optimisation of PV plant locations in South Africa in the context of the seasonal and diurnal cycles associated with the system load profiles and solar generation profiles. The distribution of a normalised per-unit generation capacity is optimised across a set of locations chosen to represent the diurnal cycle along a west-east axis and the seasonal cycle along a north-south axis, using local solar irradiance profiles for the candidate sites. Optimisations are conducted for a range of objective functions representing different scenarios defined in terms of seasonal considerations and time-of-use (TOU) periods using both genetic algorithm (GA) and pattern search methods in the MATLAB simulation environment. Comparative analysis of the optimisation results indicate that the latitude of PV plant locations plays a significant role in seasonal performance, while optimisation along a longitude dimension offers higher power generation during daily peak demand periods.

Thermoelectric generator (TEG) converts heat energy into electrical energy when there is a temperature gradient between top and bottom surface of the device. Generally, large electronic system or electronic display generates heat which dissipate via the surface of the device which may affect the functionality and lifetime of the systems or devices. Therefore, TEG can be used to utilize the heat and converts into useful electrical energy while keeping the temperature down. This paper discusses the application of the TEG in powering an RF transmitter circuit. This mechanism is referred to as self-powering whereby the RF transmitter is powered by the heat itself without the use of a battery. Once the threshold of the voltage, which is 2.9 V is being generated by the TEG, the RF transmitter controller unit will be trigger and a bit signal will be sent to a receiver station at a few meters away. In the experimental setup, hotplate is being used to simulate the heat dissipated from the ambient environment. A power conditioning circuit for the TEG is also presented in this paper.

This paper evaluates a micro generator based on a piezoelectric transducer bending mechanism where impact force is being exerted onto the bending beam and hence generating electrical power across an external resistive load. The proposed bending mechanism prototype has been manufactured by using 3D printer in order to conduct the evaluation. A free fall test has been conducted as the evaluation method with variation of masses and different fall heights which produce different forces. In this experiment a piezoelectric transducer with size of rectangle 32mm in width, 70mm in length, and 0.55mm in thickness used to conduct the experiment. The experiment results show that the instantaneous AC volt output peak is increasing toward the maximum voltage of about 50V when an impact force of about 80N and above is being applied. It is also found out that a maximum DC power of about 8.8mW is generated at an impact force of 50N when it is connected to an external resistive load of 0.175KΩ.

This paper proposed a Cuckoo Search Algorithm (CSA) method to identify the optimal location and size of shunt capacitor in radial distribution system. The main objective is to reduce the power loss in the system by using the reactive power compensation strategy. The proposed method is tested on IEEE 33-bus and 69-bus system and then verified with Particle Swarm Optimization (PSO). The proposed method results seem to surpass the solution given by PSO technique not only in power loss reduction, but also in convergence performance.

In this paper, a fast-synchronization between grid and inverter based on virtual synchronous converter (VSCon) technique is achieved in single-phase inverter. Consequently, this technique is designed and simulated in Matlab/Simulink platform to perceive the significances during variation of grid load parameters. The VSCon is implemented for inverter output control that has a behavior of grid voltage and frequency synchronization using droop control mechanism. This technique has been tested in inverter-microgrid connection with several loads connected. In case of 0.1 Hz grid frequency changes in grid test, it takes nearly 230ms to synchronize between inverter and grid frequency even with loads connected to the test system. Hence, this proposed technique can be implemented in microgrids with several distributed generation sources without using the PLL for fast synchronization between grid-inverters.

In the photovoltaic (PV) emulator application, an accurate PV mathematical model is needed to ensure the emulator can produce the same current-voltage (I-V) characteristic of a PV panel. The PV circuit model is able to simulate the PV panel accurately. However, this model requires the numerical method to solve the implicit equation of the model and the complex parameter extraction can burden the PV emulator controller. A simple and flexible PV model is needed for the PV emulator without compromising its accuracy. Two interpolation models are compared in term of adaptability, simplicity and accuracy with single diode model with series resistance (1D1R model) to determine the suitable PV model for the PV emulator system. The 1D1R Model is more accurate and adaptable compared to the interpolation models. However, the Interpolation models perform faster compared to the circuit model.
