In recent years, deep learning techniques such as Long Short -Term Memory (LSTM) neural networks have shown great potential in improving the accuracy and efficiency of time-series forecasting tasks, including electricity demand forecasting. This research proposes an LSTM-based neural network architecture for short-term electricity demand forecasting. The proposed model is evaluated on real-world electricity demand data, and the results demonstrate its effectiveness in predicting future demand patterns. The model's performance is evaluated using the Mean Squared Error loss function and the Root Mean Squared Error metric. The proposed model shows promising results compared to traditional time-series forecasting models. The results suggest that LSTM-based neural networks can be a powerful tool for electricity demand forecasting, providing more accurate and efficient forecasting models that can help improve energy system planning and decision making.","PeriodicalId":383103,"journal":{"name":"Journal of Electrical Engineering and Automation","volume":"2 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120916929","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 presence of harmonics in electrical supply can lead to a number of problems, including: Overheating of equipment, Power quality issues, Extra energy consumption etc. This research aims to provide a cost-effective solution to reduce harmonics in three phase inverters and improve power factor without using any hardware components such as filters and multi-level inverters and by simply changing control pulses of the inverter switches. This research provides a comparison of three most popular inverter control techniques SPWM control, THPWM control and SVPWM control techniques of three phase inverters. All these techniques were compared with the help of MATLAB-SIMULINK and the best control technique with lower order harmonics and less power factor was determined.","PeriodicalId":383103,"journal":{"name":"Journal of Electrical Engineering and Automation","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132199200","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}

During severe voltage sags, weak grid integrated VSIs may fail synchronization with the grid.These inverters' transient stability under severe grid disruptions is weak and significantly different from that of synchronous machines. To prevent the side band oscillations in the weak grids, the emerging inverters based on grid-forming are preferred over the grid following inverters in the weak grids. These inverters synchronise with the grid using a power-based synchronisation technique in order to prevent the instability brought on by a typical Phase Locked Loop in weak AC grids. This study presents a comprehensive review of the transient stability improvement of Grid-Forming VSIs.","PeriodicalId":383103,"journal":{"name":"Journal of Electrical Engineering and Automation","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115122975","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}

Due to its inexpensive cost and electrical isolation properties, it is mostly employed in low power applications. It is well known that high frequency switching results in losses and lowers inverter efficiency, particularly at low powers. Consequently, a flyback DC-DC converter that is run in a closed control loop is explained in this study. Closed-loop control is the proposed topology for the flyback converter. For the same input/output conditions, the findings from the closed-loop converter are compared to those from the open-loop feedback topology. A closed-loop flyback has been found to be more effective than an open-loop flyback. MATLAB simulates the outcomes. One of the high frequency devices is the flyback converter.","PeriodicalId":383103,"journal":{"name":"Journal of Electrical Engineering and Automation","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117116825","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}

Although MPPT's incremental behaviour algorithm is simple and easy to implement, despite its usefulness, this method is beset by several limitations which include a slow convergence rate towards the optimal operating point, significant oscillations surrounding the maximum power point at steady state, and momentary system movement away from the maximum power point after sudden changes or variations in irradiation. For these reasons, an improved MPPT Fuzzy Logic Control-Incremental conductance (FLC-IC) algorithm is proposed in this study. And the adjustment in the input variables of the MPPT Incremental Conductance algorithm controlled by the fuzzy intelligent control algorithm increases the convergence speed, decreases the oscillations, and remains stable despite radiation variations. The algorithm is simulated and applied in a charge controller that operates using the solar energy, and the outputs observed highlights the effectiveness of the proposed algorithm that is proposed over the IC algorithm in terms of speed and efficiency.","PeriodicalId":383103,"journal":{"name":"Journal of Electrical Engineering and Automation","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133737088","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}

With the rapid development of social technology, the application field of robots is expanding. In this paper, the control core of the proposed dancing robot is STM32F103C8T6 single chip microcomputer, the upper arm is controlled by the steering gear, the feet are two flexible wheels, and the DC deceleration motor is used as the driving motor of the wheels, so that the wheels of the robot can realize free movement and complete the dancing action of the robot. The power needed for robot movement comes from 18650 lithium battery. In the process of robot movement, the LD3320 voice recognition module is used to control the robot's movement direction and state, the MPU6050 is used to control the robot's balance, and the JQ6500 music playback module is added to the robot to control the music playback through voice recognition. After the power of dancing robot is turned on, the dancing robot starts to adjust itself to make its posture in a balanced and upright state, and then waits for the user to issue a command. The dancing robot has simple human body function and can complete simple dance actions such as moving forward and backward, walking left and right, turning left and right, and has voice function, and can also play music. The operation password is simple in the process of application, which makes it convenient for the user to use. In addition, the dancing robot is small in size and can move freely with good practical effect, regardless of the user’s age.","PeriodicalId":383103,"journal":{"name":"Journal of Electrical Engineering and Automation","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125866956","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 management of infrastructure manually in any organization or institution is a tedious task. In order to make the management of infrastructure in courts automated, an application is developed that maintains every detail of all infrastructures and IT stocks in the courts. Users can view the purchase date, warranty period, and location of the infrastructure in the court. A unique QR code is generated for each piece of furniture and IT stock to access its details. The Infrastructure Management System is touted as a revolution in court management. This application saves time and workload.
