Conversion of DC to AC is widely used as an essential need for the power system to harness renewable power source in this era. Multilevel inverter is a mechanism which capable of harnessing these renewable energies. Unfortunately, harmonics occur in the system due to distortions and causing much unwanted problems at the power output. Therefore, the elimination of harmonics and reduce Total Harmonics Distortion (THD) are needed to maintain good power output. Application of Selective Harmonics Elimination Pulse Width Modulation (SHEPWM) can be used in the multilevel inverter to solve the problem. In this paper, optimization algorithms such as Particle Swarm Optimization (PSO), Whale Optimization Algorithm (WOA) and Sine Cosine Algorithm (SCA) were applied for finding suitable switching angle for SHEPWM. The calculated switching angle was applied into seven-level five-phase multilevel inverter for various modulation indexes. In addition, the simulation of the multilevel inverter also done using PSIM software. The results show that the selective lower order harmonics, 3rd and 7th are completely eliminated for all three algorithms. In addition, the time taken for newly discovered algorithms to find switching angles for seven-level five-phase inverter is faster compared to PSO.

Evaluation of crashworthiness safety of lithium ion batteries is of growing importance due to their usage in battery packs for EV applications. Crash event may lead to deformation of cells in the battery pack causing short circuits or contact of cathode and anode due to separator damage. This leads to hot spots and subsequent electrolyte decomposition, heat and vent gas generation and hazardous thermal runaway events. Battery state of charge (SoC) is an important factor while evaluating the mechanical response of cell to deformation and the short circuit and thermal runaway behavior. In this research, quasi static deformation tests are performed on 18650 battery cells with different SoC values to understand the SoC dependent mechanical behavior and short circuit of Lithium ion Batteries. The structural and electrical response of the Lithium Ion battery (LiB) under loading is assessed. The failure stresses and buckling loads are computed for compression and bending tests respectively. Results show that mechanical and electrical behavior of LiB is highly dependent on SoC. The results shed light on the failure behavior of the Lithium Ion batteries and aid in enhancing crash safety of LiBs and design of related systems.

Non-intrusive load monitoring is widely appreciated technique for managing segregated-level energy-efficiency. Event detection algorithms play a crucial role in non-intrusive load monitoring applications. This paper proposes a new unsupervised hybrid event detection algorithm that tracks the difference and standard deviation of the aggregated load data. To evaluate the performance of the proposed algorithm, simulations are carried out on 24 hours of real-world load data from a single household having diverse load elements. This paper also assessed the sensitivity of the input parameter on the performance of the proposed event detector. The proposed hybrid event detection algorithm performed well and accomplished highly promising results.

Cost/benefit analysis of power system is one of the most challenging task due to the impact of electric utility deregulation and market competition. However, it becomes an essential factor in order to determine the system reinforcement and expansion projects. A major role in the application reliability concepts and accomplishment of an acceptable level of reliability is economic. Therefore, it is important to determine the optimal reliability level at which the reliability investment achieves the best results in reducing the customer damage costs due to power supply interruption. This paper presents an assessment of reliability cost/benefit index of expected customer interruption cost (ECOST) by considering power system contingency which are load adjustment and transmission line tripping by applying the sensitivity analysis. ECOST index quantifies the reliability of power system in terms of monetary. The value of ECOST is evaluated based on load increment/decrement and transmission line tripping. In order to calculate ECOST, load curtailment is performed. IEEE Reliability Test System 1979 (IEEE RTS- 79) is used to validate the assessment of ECOST due to load adjustment and line tripping. The findings have proved that the ECOST increases with the increased of the total loading condition and line tripping. Therefore, this method could be applied in order to assist the power system utility in monitoring the contingency in the system.

Overhead transmission lines are prone to various natural disaster and phenomena which lead to system fault. System fault causes tripping which can be due to various root causes such as lightning strikes, tree encroachment, crane encroachment and defect equipment. In this paper, fault characteristics from different root causes are studied and analyzed based on field data extracted from the Digital Fault Recorder (DFR). It is found that different fault types of overhead transmission line have identical fault signatures in terms of current and voltage waveform. Moreover, to quantify the fault signatures, several indices are extracted to identify the root cause of fault. The indices are based on pre-fault and fault event current and voltage waveforms. These findings can be beneficial to enhance the decision making on identifying the root cause of fault.

Malaysia is strategically located in the tropical region which is abundant in solar resources. Nevertheless, countries with tropical climatic condition is known for the high passing cloud events. This phenomenon has introduced technical challenges to the integration of solar photovoltaic (PV) system to electricity networks. The high intermittency of solar irradiance will lead to rapid solar output power fluctuations, which is harmful to the operation of the electricity grid. Hence, this paper aims to utilize a battery energy storage system to smoothen solar output fluctuations under real weather conditions in Malaysia. More specifically, two smoothing methods were considered to determine the required battery capacity probabilistically for a grid-connected solar PV system installed at the Faculty of Electrical Engineering, Universiti Teknikal Malaysia Melaka.

In this paper, the dielectric properties of five HVDC cable-grade polypropylene (PP)-based dielectric materials are discussed. Two type of nanofiller, codename N1 and N2, with different weight percentages (% wt), were considered. Breakdown strength, temperature-dependent dissipation factor, dielectric constant, and space charge behavior were measured to characterize the materials. It is found that the addition of nanofiller could increase DC breakdown strength. Temperature-dependent dissipation factor on filled samples is slightly higher than unfilled sample but still below 0.4% at 200 C. 1% wt N1-filled samples shows slightly higher dielectric constant than unfilled sample, while as wt is increased to 2% it becomes slightly lower than unfilled sample. 1% wt N2-filled samples shows slightly lower dielectric constant than unfilled sample. Space charge injection threshold of 1% N1-filled samples is slightly higher than unfilled ones, while the accumulated charge is strongly dependent on the electric field applied. At 50 kV/mm electric field of weight percentages of N1 and the addition of N2 filler could decrease space charge accumulation, lower than the unfilled sample.

By the decision of the Government of Mongolia, work was initiated to electrify remote cities and rural areas and connect them to the central electricity supply. In this context, new methods and technologies have been introduced to transfer long-range, high-quality electricity and to save investment. This is evidenced by the introduction of a new voltage standard, which currently uses a voltage level of 15 kV in the distribution network. Since the pilot launch of 15 kV, 4,279 km of 15 kV transmission lines and 268 substations have been built and are in operation. Electromagnetic pollution is one type of environmental pollution. The main sources of electromagnetic pollution are power electrical equipment. We have developed a simple calculation methodology to determine electrical and magnetic field intensity at a particular point using basic parameters and geometric dimensions of power transmission lines and support. This article discusses the theoretical foundations of the developed methodology and mathematical apparatus.

In residential energy management (REM), time of use (TOU) of appliances scheduling based on user-defined preferences is an essential task performed by the home energy management controller. This paper devised a robust REM technique that capable of monitoring and controlling residential loads within a smart home. The method is based on an improved binary grey wolf accretive satisfaction algorithm (GWASA), which is founded on four hypotheses that allow time-varying preferences to be quantifiable in terms of time and device-dependent features. Based on household appliances TOU, the absolute satisfaction derived from the preferences of appliance and power ratings, the GWASA can produce optimum energy consumption pattern that will give the customer maximum satisfaction at the predefined user budget. A cost per unit satisfaction index is also established to relate daily consumer expenses with the achieved satisfaction. Simulation results on two peak budgets from $1.5/day and $2.5/day are carried out to analyze the efficacy of GWASA. Accordingly, the result of each of the scenarios is compared with the result obtained from three other different algorithms, namely, BPSO, BGA, BGWO. The simulation results reveal that the proposed demand side residential management based on GWASA offers the least cost per unit satisfaction and maximum percentage satisfaction in each scenario.

Govt of India has aimed to create 100 smart cities with the help of recent technological advancements. In the state of Tamil Nadu, the capital and an industrial city Chennai is going to become a smart city soon. Presently most of the electrical systems used in Chennai are overhead systems, and these systems were severely damaged by Vardah cyclone on Dec 2017. It took more than a weeks’ time to restore the power supply to the city. The idea behind smart city is to monitor and protect the system from unexpected outages. By converting the overhead systems into underground systems, uninterrupted power supply can be provided. EMI studies have become an important part in planning & implementation of power systems, design of high voltage power apparatus, healthcare etc. Whenever underground systems are planned, it is essential to perform EMI studies as a part of design procedure. The objective of this paper is to analyze the EMI produced by these underground power cables and to determine the optimized value of the radius of the cable using Genetic Algorithm (GA) also understand the remedies to suppress the exposures within safe limits. EMI studies have been conducted using Ansys 2019.
