Currently, the electrical smart grids are very effective in solving the problems of traditional electrical networks. The smart implementation of Demand Response Programs (DRPs) has significant impact on the decreased costs and increased network reliability. In this paper, the integrated model of time of use demand response program and issue of Dynamic Economic Emission Dispatch (DEED) is presented. In the integrated model, the production cost and emission are minimized and the optimal price rate is determined at different periods at the same time. Considering the various non-linear conditions such as point-valve effect, prohibited operating zones and spinning reserve, the problem become completely nonlinear and complex, which is solved using Random Drift Particle Swarm Optimization (RDPSO) algorithm. The final model is applied to a ten-unit system and proves the results of final model implementation advantages.

In this paper, Electrostatic-Discharge (ESD) reliability study of 45-V HV pLDMOS devices with the source-side discrete islands is investigated. A pure pLDMOS transistor is always frail in ESD harms (It2= 0.107-A). However, if a pLDMOS device with two embedded SCRs (drain side npn-arranged); the corresponding It2 current can be upgraded to 0.644-A. Furthermore, as a pLDMOS-SCR (npn-arranged stripe type) extra with the source discrete technique, the trigger voltage (Vt1) values of these pLDMOS-SCR devices have slowly increased with the OD-rows number decreased. And, a highest Vt1 value on DIS-3 of 48.49-V can be obtained. Meanwhile, the best secondary breakdown current (It2) value is 4.032-A. Then, a source discrete technique is good for ESD robustness in these pLDMOS-SCR compound devices.

Mineral oil is a petroleum-based oil which is nonrenewable and is running out in the future. It is also non-biodegradable, thus, it can be harmful to the environment when there is oil spillage. Therefore, this work is conducted with an intention to reduce the usage of petroleum-based oil by mixing it with natural ester oil. This is achieved by mixing the mineral oil (MO) and palm fatty acid ester (PFAE) oil with a ratio of 20:80 and vice-versa by using homogenizer machine. Through the homogenizing process, each mixing sample is vibrated for 20 minutes to complete the miscibility of both insulating liquids. AC breakdown voltage test compliance with ASTM D1816 standard is conducted on the oil mixtures to investigate their dielectric breakdown performance. Comparison is made with the virgin MO and PFAE that used as benchmark. The results suggest that the optimal breakdown voltage was obtained by blending an 80% MO with 20% PFAE to improve the dielectric breakdown performance of mineral oil alone.

The electrical energy consumption associated with sanitary water heating makes up a large part of the total load associated with residential energy consumption, and therefore load models thereof could find use in various Energy Management (EM) applications. This paper presents the results of an investigation to model the electrical load associated with the combined sanitary hot water heating systems of 21 university residences using Adaptive Neuro-Fuzzy Inference Systems (ANFIS) within the MATLAB platform. The desired prediction horizon is defined as medium term, i.e. up to a year ahead forecasting. The training inputs considered include temperature, day of year, day of week, and daily time interval. The effects of compartmentalising the dataset into subsets representing different characteristics, thereby deriving different models representing different cyclic periods, are explored. K-fold cross validation is used in conjuncture with Mean Average Percentage Error (MAPE) calculations to provide a comprehensive breakdown of model performance.

The paper presents an analysis on the effect of control surface of the Single-Input Fuzzy PI Controller on the brushless DC motor performance. The analysis is carried out to determine the most suitable and appropriate control surface that could be used for the BLDC motor drive control system. The control surface of SIFPIC is mapping in one dimension using a piecewise linear approximation as the SIFPIC is simplified to sole-input variable. The analysis is done through simulation work using MATLAB/Simulink with different degrees of non-linearity of control surface. The performance of BLDC motor is observed through speed, current and torque response. From simulation result, an appropriate control surface is chosen for SIFPIC that most suit for the current system.

This paper presents a scheme to improve the input current ripple of capacitor-less inverter system using a predictive control algorithm. The capacitor-less inverter, which is using small capacitor in the dc-link, has several advantages such as competitive cost, compact size, enhanced reliability, and elimination of initial charging circuit. However, the dc-link voltage shows instability because the energy storage capability of the small capacitor is not sufficient. Therefore, DC-link shunt compensator (DSC) should be used in capacitor-less inverter to stabilize the dc-link voltage and nullify the negative impedance by injecting the compensation current. However, the general proportional integral (PI) current controller, which has wide bandwidth to track the compensation current having a sinusoidal waveform, is weak for the noise and disturbance. This paper proposes a model predictive control (MPC) algorithm to improve the performance of DSC. Given the optimal duty cycle calculated by estimating the next state current, the proposed algorithm has a fast dynamic response and accuracy. The proposed method is verified through PSIM simulations.

Glazed glass cap and pin insulators that have been removed from the transmission line, have electrical characteristics ensuring them to be reused and reinstalled on lower voltage distribution level lines. The electrical properties determination involving insulator resistance, self-capacitance, corona inception voltage and flashover voltage were measured using AC high voltage generating unit. The advantage of this paper is that it presents, an effective new technique to select aged glazed glass insulator based on measured characteristics, in combination with likelihood of flashover occurrence and compatibility factor, making I-type string insulator design more deterministically and particularly for 33kV distribution line application. Using technique employing coefficient of compatibility, it was found that transmission line glazed glass cap and pin insulator can be recycled, selected and reused for distribution line insulation application.

This paper presents the performance analysis and improvement of electric power generation for Oscillating Water Colum (OWC) wave energy converter using Finite Element Analysis (FEA). The existing power take-off system in OWC is based on induction machines which not only suffer from poor efficiency but require significant maintenance also. Conversely, synchronous permanent magnet (PM) generators offer numerous advantages and are adopted largely in wave energy conversion systems. This work proposes a synchronous permanent magnet (PM) generator with segmented magnets which enhances the electromagnetic characteristics and improves the efficiency as compared to conventional generators. In order to determine electromagnetic performance FEA has been carried out, two modes; no-load and full-load operations are analyzed in detail. The proposed synchronous permanent magnet (PM) generator is compared with conventional and the results such as; magnetic flux density, induced-voltage and flux linkage along with efficiency evaluation are presented.

The use of renewable energy such as solar is nowadays exceptionally used in electrical systems due to increasing on power demand. Thus, power electronic converters are widely used to perform the required energy conversion. However, the device such as multilevel inverter (MLI) is designed without harmonic-less. This phenomenon will create power quality problem such as increases in total harmonic distortion (THD). Moreover, increasing of the nonlinear loads usage also contributed in harmonic problem. This paper presents the single phase shunt active power filter (APF) based on instantaneous power theory. The performance of APF depends on instantaneous power theory control strategies which combined with the cascaded MLI to reduce the THD in load current. It enables to provide compensation of harmonic and reactive power in good performance. Generally, the instantaneous power theory is implemented in three phase APF. However, it can be used in single phase by assuming equal voltage and current and the other two voltages and currents are duplicated with 120° angle shifting that will be used for input of instantaneous power theory. The system is validated through extensive simulation with the aid of MATLAB/SIMULINK Toolbox to analyze the output waveform and THD values of current and voltage. The implementation of shunt APF to MLI, the THD of current can be reduced around 70% to 84%.
