Switched-capacitor (SC) based inverter topologies are very attractive for renewable energy applications to step-up low dc voltage to higher ac voltage in single-stage without the need of front-end dc-dc converters, thus improving overall system efficiency, reliability and power density. This paper presents a new modular multilevel inverter based on switched-capacitor technique. Herein, series-parallel conversion technique is utilized to effectively self-balance the switched-capacitor voltages. Compared to other latest SC-based MLIs topology, the proposed structure features several advantages such as: low number of conducting semiconductor devices in load current paths and SC Charging paths. In addition, each capacitor is charged for at least half of the fundamental period that reduces voltage ripple and improves the inverter efficiency. Consequently, the presented inverter is suitable for high levels generation to achieve the rated ac voltage directly from a low voltage dc source. The merits and feasibility of the proposed inverter are verified through simulation for seven levels with sinusoidal PWM at different modulation indices and load conditions.

This paper proposed a method to determine the optimal location and sizing of Distributed Generation (DG) for power loss minimization using Ant Lion optimizer (ALO). The analysis also covers the effect of DG installation to voltage improvement and maximum system loadability index. ALO is an optimization algorithm that based on the nature interaction between ants and antlions. The nature interaction consists of five steps of hunting prey such as random walk of ants, building traps, entrapment of ants in traps, catching preys, and rebuilding traps. The ALO algorithm is tested on IEEE 69-bus distribution test system. The system will find the optimal location and sizing with corresponding load increase until it reaches the maximum system loadability (MSL) of the network. DG are usually attached to the end terminal at the load side of the system that refers to a technology that generate electricity at or near where it will be used such as solar panels and combined heat and power. The result of test function shows that the proposed algorithm can provide accurate yet competitive result in terms of power loss minimization, maximum system loadability enhancement and consistency.

Since the commercialization of Lithium ion batteries (LiBs), strong strides have been taken to enhance the performance (power and energy density, cycle life) while reducing manufacturing cost per kWh. With the push for adoption of electric vehicles worldwide, LiBs are the preferred choice for rechargeable energy storage systems (RESS). The performance and cost of electric vehicles (EVs) are driven by the research in battery technology. With the EVs presenting huge potential towards sustainable energy futures, driving down carbon emissions, improving air quality index (AQI) – a critical problem in world’s most metro cities and reducing dependency on oil and petroleum, government has taken strong strides in promoting EVs as a viable business opportunity. Government plans to phase out internal combustion engine (ICE) vehicles over the next 10 to 30 years. Many OEMs have launched EV platforms and global EV sales totaling 2.3 million in 2019. Albeit government subsidies and regulations, EV market captures a small share (~2%) in the global automotive market. Thus, to prove as a feasible replacement for ICE vehicles, rapid advancements are required in battery technology. This paper provides a detailed review of the current battery technology analyzing the current EV RESS requirements and challenges faced in integration. Lastly, future scope and directions for EV centric LiB research discussed.

This manuscript proposes a robust hydrogen-based grid system to improve the power quality of the microgrid. Advancement in hydrogen technologies such as electrolysis and fuel cell in recent times allow for more efficient and less costly conversion between electrical energy and hydrogen. Electric frameworks dependent on hydrogen energy are now being used as a replacement for big energy storages like battery. The power variations become smoother when a hydrogen-based energy system is used that has a storage of high levels of pressure as opposed to electrical systems that generate significant amount power from conventional wind or solar energies. In order to interconnect an electrolyser and fuel cell inside of a grid distribution system with low level of voltage, higher efficiency, and reliability, a bidirectional multilevel current source inverter is utilized. A simulation model of the planned structure is developed utilizing MATLAB/Simulink, showcasing the appropriate behavior under different circumstances.

Palembang is one of tropical area with high lightning density as it is located on wind reversal area. The position of Palembang Light Rail Transit rolling stock is higher than surrounding object, thus it is an easy target for lightning strike. External lightning protection systems, with lightning event counter, for Palembang Light Rail Transit only protect stations and important objects in viaduct such as signal and telecommunication poles, and most of the track are not covered. The objective of this paper is to find lightning detection system efficiency from ground and space as well as its correlation with lightning event counter data on existing external protection system. Lightning detection system data from ground and space in Palembang have positive correlation, even though flash rate density map from space have lower resolution than the other one. Data from lightning event counter also have positive correlation with lightning detection system data from space. Even though they all have positive correlation, it turns out that lightning strike density from lightning event counters are 5 times higher than the space one. So, we can conclude that lightning detection system from ground absolutely have higher sensitivity and resolution than the space one. For initial or general monitoring reasons, lightning detection system from space might be enough to provide yearly, monthly, or diurnal lightning activity data in certain area. With all these correlations, it is clear that we can use lightning detection system data from ground and space to improve safety of Palembang Light Rail Transit.

Forecasting is an essential element in supporting the integration of large-scale Grid-Connected Photovoltaic System (GCPV). However, meteorological data vital for accurate forecasting may not be available for a specific location of interest. This paper investigates the use of data obtained from online weather platforms in forecasting photovoltaic (PV) output power when site data is missing or unavailable. Three online platforms were compared and one is chosen as the basis of this paper. The analysis is benchmarked using real ground-based measurement installed at the Faculty of Electrical Engineering, Universiti Teknikal Malaysia Melaka (UTeM). For forecasting, the Linear Regression (LR) method is used because the performance is easier to interpret. Comparison has been made between the real, calculated, and forecasted PV output power. Root Mean Squared Error and coefficient of determination are the statistical metrics used to evaluate the forecasting performance. The results show that the chosen online weather platform has the capability to complement missing or unavailable local weather parameters. On top of that, forecasting using a simple machine learning algorithm provides marginal improvement compared to calculated values with RMSE of 5.95% and 7.62% respectively.

The concern regarding the Extremely Low Frequency (ELF) Electromagnetic Field (EMF) exposure to the surrounding has been a rising topic since the rapid advancement of technology over the past decade. One of the main concerns is from power line such as electrical substation, transmission line or tower that carry high amount of voltage and current from power plant to the distribution substation, since these systems and technology are among the contributing factors of emanating ELF EMF for magnetic and electric fields. By using 3D electromagnetic software, a transmission cable line and a shielding barrier were designed and simulated in the software to observe the behaviour of electric and magnetic field emission performance. The experiment is done by mitigating the distance of shielding barrier from the source and changing the thickness of the barrier. The simulated results show that the electric and magnetic field strength are decreasing with increasing distance or shielding barrier. The emissions also can be mitigated by varying the geometry of the shields and changing the shielding barrier material.

The growing demand on the renewable energy systems that work through battery cells has provided a high interest in the DC/DC Buck-Boost converters due to their capability to both amplify and attenuate the voltage that is supplied from such cells. An important feature in the design of these converters is the ability to operate in continuous conduction mode (CCM) so as to lower harmonic distortion and avoid the need for active control on inductors. In this paper, we investigate the design requirements for CCM operation in a reported single switch quadratic DC/DC converter by constructing a simulation model to validate the theoretical gain equations of the converter and check their agreement with the reported results. The simulation results obtained not only revealed inaccuracies in the reported gain equations but also confirmed the agreement between the proposed gain equations in this paper with the expected behavior of the converter.
