People have begun to examine the potential positions of dc systems in both current and future power equipment due to the rise in the use of renewable energy and the implementation of energy storage in recent decades. Because of its efficiency and power density, dc voltage representation has found use in a wide range of fields, including data centres, the aerospace industry, and dc micro-grids. Resonant DC-DC converters, with their gentle switching and minimal EMI, provide a promising solution to these problems. Finding and examining the various modes of operation of the converter while employing the pulse-removal approach is the primary objective of this study. The new method of operation utilises variable frequency and variable phase displacement in sub-resonant mode, which promises to reduce the transformer size while also facilitating the soft-switching change of the insulated gate bipolar transistors (IGBTs) and line frequency diodes on the rectifier side. The pulse elimination approach, a revolutionary mode of operation for the converter, involves phase and frequency shift modulation at varying rates. Using the results of MATLAB/SIMULINK simulations, the suggested control technique may be utilised to establish the baseline switching function configuration necessary to attain high power efficiency.","PeriodicalId":199980,"journal":{"name":"Journal of Energy Engineering and Thermodynamics","volume":"2021 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128060272","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}

The notion of the microgrid combines several microsources without interfering with the functioning of the larger utility grid. The DC and AC networks of this hybrid Microgrid are powered by photovoltaic and wind generators. Both AC and DC Microgrids may couple with energy storage devices. A microgrid powered by a combination of renewable energy sources, such as wind and solar, is shown and controlled in this project. The wind energy conversion machine is a doubly fed induction generator (DFIG), and it is coupled to a battery bank through a DC bus. Solar power is efficiently converted utilising a DC-DC boost converter from a solar photovoltaic (PV) array and then evacuated at the common DC bus of DFIG. With the line side converter's droop characteristics implemented, voltage and frequency may be regulated using an indirect vector control. A battery's energy level is monitored, and the frequency set point is adjusted accordingly to prevent excessive charging or discharging. When wind power is not available, the system can still function. Maximum power point tracking (MPPT) is a feature of the control algorithm used by both wind and solar energy blocks. All conceivable operational scenarios have been accounted for in the system's design, making it fully autonomous. An external power supply is included into the system and may be used to charge the batteries whenever needed. The feasibility of wind and solar energy, imbalanced and nonlinear loads, and a depleted battery are only some of the scenarios simulated in this paper, along with the corresponding simulation findings.","PeriodicalId":199980,"journal":{"name":"Journal of Energy Engineering and Thermodynamics","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130685095","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}

In order to optimize the power output, an electronics device should be integrated with solar PV system. A high classical classical single ended primary inductor converter SEPIC converter for renewable energy applications was designed, constructed and experimentally tested. The voltage multiplier cell (consists of two diodes and two capacitors) was incorporated with SEPIC to design a DC – DC boost converter for PV application. The new converter can improve the capacity of 10 V DC input to output 60 V DC, the design circuit will boost input voltage and maintain a constant voltage output. The performance of the proposed topology was authenticated and the result achieved from the implemented prototype are in good agreement with the design strategies. The effects of input parameters such as sun radiation and useful power input on PV system and DC-DC converter outputs were investigated. Results comfirmed that the DC-DC converter was perfectly designed using Multisim software and accurately constructed, when integrated with solar PV system under no load and on load conditions.","PeriodicalId":199980,"journal":{"name":"Journal of Energy Engineering and Thermodynamics","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134404569","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}

According to data compiled by the Prevention Council while the Environmental Protection Association, the average mortality toll from fire is 10.5% and from petrol is 11%. This research endeavour addresses the issue of electrical appliance safety. IoT-based control system with gas, fire and temperature sensors; lcd(16x2) displays system status and sensor data. In this setup, loads are managed mechanically based on sensor readings. The Internet of Things (IoT) can store and track this information. The system provides safety against toxic gas and fire hazards. Wi-Fi networks with IEEE 802.11 wireless standards are ideal for homes and offices with little space. The primary goal of this project is to ensure the safety of the building in which this design is implemented; for example, if a fire is detected by a fire sensor, a motor pump will be triggered to disperse water as part of a sprinkler system, and if a gas sensor detects harmful gases, an exhaust dc fan will rotate to vent the area. The temperature sensor will monitor the interior temperature and activate the exhaust fan if the temperature rises beyond the set limit. All of the sensor data and the status of each linked function will be shown on an LCD, and a buzzer will sound a warning. Proteus, a professional design suite, version 8.6, may be used to simulate this proposed safety solution, and Arduino IDE, version 1.8.19, can be used to write the necessary code. A working prototype is built and put through its paces as an experiment.","PeriodicalId":199980,"journal":{"name":"Journal of Energy Engineering and Thermodynamics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122564810","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}

Power quality issues in the distribution system have received a lot of attention in recent years due to the extensive integration of variable renewable energy generation. Modern digital grid technology, electric spring (ES), has previously been utilised to stabilise voltage and power in a system that relies heavily on unregulated or completely renewable energy sources. To control voltage and power, it has been recommended as a demand-side strategic approach. It has been suggested that electric springs (ES) might be used as a request technology to boost the reliability and efficiency of future power grids that rely heavily on intermittent renewable energies. At now, ES is mostly used for controlling grid voltage and service frequency. This study describes a method for controlling and balancing power in a newly integrated ES and PV system configuration, and it examines how this method may be used to achieve responsive supply equilibrium in electricity distribution networks. The suggested system allows for the maximum amount of collected PV power to be sent to the grid via the ES, while also actively regulating the energy usage of its ES-associated smart load in order to maintain a constant supply-demand power balance. Because the smart-load power associated with the ES follows a suitable usage patterns to adjust for possible forecast failures of the PV power output, battery storage is unnecessary in the suggested architecture. Excellent performance of the suggested design method is demonstrated using Matlab/Simulink simulations.","PeriodicalId":199980,"journal":{"name":"Journal of Energy Engineering and Thermodynamics","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131836934","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}
