In this paper, a preliminary idea of a new dc-dc boost converter is presented, which contains a unique feature of series resonating network. In the proposed circuit all the fundamental operations are controlled through a single low side switch. The main philosophy behind the designing of the boost converter is to offset the conventional thinking of placing the diode at the output. In this sense, the current from output capacitor is allowed to return back through the resonant network along with natural input current from source, giving rise to higher voltage gain. Compared to the conventional boost converter, the higher gain is achieved in the proposed converter using a single switch and few more components. The proposed converter is tested using PSIM simulations and under three distinct duty ratio value. It is seen that the simulated outputs are in harmony with the theoretical value and that the output voltage obtained using these duty ratio values is higher as compared to conventional boost converter.

Increasing energy requirements due to population growth, urbanization, and industrialization push to adopt energy resources that will not deplete. Pakistan is among the category of those under-developing countries that are facing an electricity shortfall of 6997 MW. Pakistan is an agricultural country and has diversified sources of biomass. The geological location of Pakistan around the Sun Belt reveals that the average solar irradiation is 5 kWh/m2/day. A case study has been done focused on a rice mill in Layyah city in Punjab province. The targeted renewable resources are rice husk (biomass) and solar energy to produce electricity. Homer Pro software is used for optimization and techno-economic analysis of the PV/Biomass hybrid systems. Eight configurations are designed against the off-grid and on-grid systems (four for each system). It is seen that the most feasible design, case-3 from the off-grid (PV-BM-DG-B) system of 300 kW configuration, shows the NPC, LCOE, and renewable penetration of 5.91 M$, 0.125 $/kWh and 99.8%, respectively, whereas, in on-grid system, case-6 (PV-BM-G) shows 3.51 M$, 0.0503 $/kWh and 97.9%, respectively. Environmental analysis reveals that these models would help in carbon emission reduction compared to grid.

The adverse environmental impact of using Chlorofluorocarbons (CFCs) and Hydro-Chlorofluorocarbons (HCFCs) as refrigerants in traditional refrigeration and air conditioning systems has been revealed. Thermoelectric coolers may present a more ecologically sound alternative since they do not require any refrigerants or other hazardous substances that contribute to the depletion of the ozone layer or global warming. In this study, a thermoelectric cooling module was built, and its cooling performance was examined by experimental and simulation approaches.

Smart grid (SG) will transform contemporary businesses by offering efficient solutions to improve existing power systems' efficiency, stability, and resilience. SG provides long-term power supply by interconnecting electrical grids and communications infrastructures. However, SGs are plagued with problems and complexities, particularly regarding capacity, reliability, and security. The main concerning issues for consumers are data breaches and malicious hacking of personal equipment. In addition, the growing integration of distributed generation (DG) and electric vehicles (EVs) has exacerbated the problem in numerous ways, including synchronization challenges, voltage regulations, malfunctions, and harmonic components in current and voltage waveforms. This paper examines the challenges and issues associated with SG, such as communication, security, energy integration, and power quality.

The most important and growing problem in the Microgrid is the power quality issues. As an excellent solution to the power quality, energy crisis, and environmental pollution, solar energy has drawn more attention. Power converters are used to integrate these renewable energy sources into the grid. The DC input energy is extensively transformed to AC output power by a two-stage conversion system consisting of a DC-DC converter at the front end followed by a DC-AC inverter. When the DC-DC converter and the DC-AC inverter are connected in a cascaded configuration, this cascaded configuration will generate harmonics in the system due to the inverter's pulsating output power. These harmonics flow in the system, affect the source (Solar PV), and significantly impact the voltage variation. This paper proposes to design power converters that will convert the DC power of solar PV into AC output power while producing minimum harmonics at the input. This research paper will employ an active power filter to reduce or eliminate harmonics in the cascaded power converters to increase solar PV lifetime.

This study proposes a novel Disturbance Observer based Adaptive Backstepping Sliding Mode Controller (DOABS-SMC) to overcome the adverse effects of parametric uncertainties and external disturbances on a single-phase inverter in stand-alone power supply mode in addition to improving the tracking time of the output voltage. Firstly, the dynamical model of the inverter in stand-alone power supply mode is established with parametric uncertainties. Thereafter, a traditional Backstepping controller (BSC) is combined with disturbance observers (DO) to remove the adverse effects of the disturbances and confirm the system's stability. To ensure the robustness of the controller, an SMC is combined with the BSC to further improve the performance of the controller. The effectiveness of the proposed controller is then experimentally verified by comparing it with traditional BSC and PID controllers. The results indicated that the proposed controller's performance is better than the other ones under the parametric disturbances and changing load.

As part of the fourth industrial revolution, low-power electronic devices require a power harvesting system to provide energy for their operation because energy harvesting technologies are crucial for enabling 90% of wireless sensor networks. While solar and thermal energy harvesting are popular methods, they have limitations such as dependence on sunlight and thermal gradients, which make them unreliable for low-wattage electronic equipment and wireless sensing networks. Power harvesting from ambient vibrations can lead to a sustainable system. Currently, there is a focus on different power harvesting principles such as electromagnetic, piezoelectric, and electrostatic. This research work presents a novel power harvester design that uses three in-plane capacitive transducers - gap-closing, overlap-varying, and pattern-varying - to operate under ambient vibrations as input energy. With low levels of input vibrations, the device moves, leading to changes in capacitance and the harvesting of reliable electrical power. The design analysis includes capacitance, frequency, and electromechanical evaluations to acquire capacitance matrices, natural frequencies for different modes, displacement covered by moving mass, charge distribution, and pressure distribution.

Perovskite solar cells (PSCs) have shown tremendous potential in photovoltaic (PV) technology over the last decade due to their outstanding optoelectronic properties and high power conversion efficiency (PCE) of more than 25%. PSCs, on the other hand, have stability and toxicity problems, which have hampered the development of this technology. Lead (Pb) is poisonous in perovskite materials and can be substituted by non-toxic materials such as tin (Sn), germanium (Ge), bismuth (Bi), and others. Furthermore, replacing organic cations in perovskite structures with inorganic ones aids in the resolution of PSC stability problems. Using SCAPS-1D, an all-inorganic lead-free cesium tin-germanium tri-iodide (CsSnGeI3) PSC with TiO2 electron transport layer (ETL) and Kesterite CNTS as hole transport layer (HTL) is numerically modelled and optimized. The device optimization of the PSC structure TiO2/CsSnGeI3/CNTS contributed to an increase in PCE of up to 4%. The modelling results showed that the PCE of the PSC structure is 27.21%, the open-circuit voltage (Voc) is 1.15V, the short-circuit current density (Jsc) is 27.69 mA/cm2, and the fill-factor (F.F) is 84.97%. Furthermore, the impact of temperature (K), defect density (Nt), and interface defects on PSC performance is thoroughly examined. This research delves into the numerical structure and device manufacturing factors for commercializing Pb-free cesium tin-germanium-based PSC technology.

The use of solar photovoltaic (PV) systems as a renewable source is gaining popularity as a means of reducing greenhouse gas emissions and meeting energy demand. However, losses associated with solar PV systems remain a challenge. In this study relationship between the average power output of a solar PV system in clean and cotton dust configurations using linear regression analysis is investigated. The data is being collected over a period of 12 days, with daily measurements of 8 hours of the average power output in both configurations. Based on the t-test, it is found that the average power output in the cotton dust configuration was significantly lower than that in the clean configuration. Linear regression analysis verified that the power output of the system decreased over time in both configurations. The coefficient of determination for the clean model is 0.1905 and the R-squared value for the cotton dust model is 0.8436. These outcomes highlight the importance of considering the effects of cotton dust growth on the performance of solar PV systems and the potential for improved maintenance strategies to overcome the related losses.

Voltage regulators, such as Buck-Boost converters, are necessary to provide constant voltage within an operating range for electronic devices. The Buck-Boost converter's duty cycle determines whether it operates in a buck or boost mode, depending on the input DC voltage amplitude. A Fractional Order PID (FOPID) controller generates the control signal based on the duty cycle, as it provides flexibility and stability for non-linear systems. Tuning the controller's parameters to achieve desired response characteristics is necessary. This study aims to compare the new Mayfly algorithm's performance with other optimization algorithms such as Particle Swarm Optimization (PSO), Artificial Bee Colony (ABC), RAO-series, etc., including meta-heuristic and non-meta-heuristic, in estimating the controller's optimal parameters for a given Buck-Boost converter model. A variable voltage input is used to test the controller's stability. The study compares results from three objective functions using different implemented algorithms. Overall, the study highlights the importance of selecting the right optimization algorithm to ensure optimal performance and stability of the controller for non-linear systems.

Overall, the study highlights the importance of selecting the right optimization algorithm to ensure optimal performance and stability of the controller for non-linear systems.","PeriodicalId":350869,"journal":{"name":"2023 International Conference on Emerging Power Technologies (ICEPT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130476818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
