The main challenge of dynamic analytical modelling of DC-MMC is the nonlinear multiplication terms in ABC frame equations for modulating oscillating signals. This paper uses the rotating DQ frame for mitigation of this challenge. This requires simultaneous modelling in zero sequence, fundamental frequency DQ and second harmonic D2Q2 frames. The proposed dynamic model is implemented in state-space within MATLAB environment. A reduced-order model is also developed by equating the second harmonic components of the proposed model to zero. The validity and accuracy of the two models are verified against a detailed DCMMC model in PSCAD/EMTDC in time domain. The results show that the proposed full-order dynamic model is in excellent agreement with the detailed PSCAD model across all variables, both in steady-state and in transient operating phases. The results of the reduced-order model show that the accuracy is decreased if the second harmonics are not considered in the model. A simple eigenvalue analysis is also presented as an application of the model.","PeriodicalId":169048,"journal":{"name":"2023 IEEE Conference on Power Electronics and Renewable Energy (CPERE)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123947665","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}

High steady-state performance, a power factor at the input side that is almost unity, and a quick dynamic response are the proposed converter performance characteristics. The number of cascaded units can be used to get a high voltage gain. In the cascaded connection, the basic architecture of one unit requires just four IGBT switches with low-voltage ratings. The converter may keep running while achieving the required voltage gain even if one of the cascaded units fails thanks to a suitable PWM-based control mechanism that is developed. Furthermore, it can solve the commutation problem in singlephase AC-AC converters. The suggested AC-AC converters may be short-and open-circuited without damaging the switching devices by employing a basic switching cell construction and coupled inductors. The operation modes and mathematical analysis for the cascaded converter are described. The proposed technique’s effectiveness and reliability are proved using computer simulation using MATLAB/Simulink. In addition, an experimental setup for the system is built on the laboratory to confirm its practicability and tested under various conditions. Already, the excellent match between theoretical and experimental data is obtained.","PeriodicalId":169048,"journal":{"name":"2023 IEEE Conference on Power Electronics and Renewable Energy (CPERE)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124149402","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}

It is used to convert the DC power produced by many strings of the PV modules to AC power which is injected into the grid. So, it is considered the core of the PV plant. It affects distinctly the PV plant availability. So, the partial or total failures of inverters negatively affect PV plant availability. The inverter is designed to operate under specific conditions. Also, it is designed to produce AC power with technical specifications based on the input DC power characteristics. There are two types of data monitored during the inverter operation. The first type is the instantaneous data stored in the communication board memory. It is continuous time values that represent the waveforms of inverter outputs such as voltage, current, frequency, etcetera. Often, in the event of catastrophic failures that lead to the complete burning of the inverter, the instantaneous data is lost and can’t be restored. The second type is the operational data monitored and recorded by the SCADA system for each interval. It includes discrete RMS of inverter outputs such as voltage, current, frequency, etcetera. Most SCADA systems are designed to record data per minute. Hereby, the operational data is considered the sole data source in the event of catastrophic failures of the PV inverter. This paper presents an analytical model of the inverter operational data before fault occurrence. The objective of analyzing the inverter operational data is to deduce the thread-tip observation that indicates the failure causes of the grid-tie PV inverter.","PeriodicalId":169048,"journal":{"name":"2023 IEEE Conference on Power Electronics and Renewable Energy (CPERE)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126514663","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}

An energy management system (EMS) algorithm using MATLAB and Simulink was designed to efficiently manage equipment in the Hybrid Microgrid with aim of maximizing the contribution of renewable sources and minimizing the operation of the diesel generator. A sensitivity analysis of the installed capacity for both PV and Wind was performed and it was found that the optimum ratings were $300 mathrm{~kW}$, and $200 mathrm{~kW}$ for the $P V$ and Wind respectively. The optimum size of the tank to achieve the minimum levelized cost of electricity (LCOE) was determined to be $40 mathrm{~kg}$ of stored H2, this would achieve an LCOE of $1.565 mathrm{EGP} / mathrm{kWh}$ which is lower than the LCOE of $2.213 mathrm{EGP} / mathrm{kWh}$ in case the load is completely dependent on the diesel generator. The optimum ratings of the electrolyzer, fuel cell, and diesel generator were found to be $150 mathrm{~kW}, 100 mathrm{~kW}$, and $250 mathrm{~kW}$ respectively. In addition, a sensitivity analysis was carried out for different parameters of the system such as project discount rate and annual increase rate in fuel price. Moreover, the carbon dioxide $left(mathrm{CO}_{2}right)$ emissions of the load on the diesel generator alone and the micro-grid are $9.187 times$ $10^{5} mathrm{~kg} /$ year and $2.557 times 10^{5} mathrm{~kg} /$ year respectively. Using the proposed sizing of the micro-grid leads to a decrease in emissions by around 72.44 % per year.","PeriodicalId":169048,"journal":{"name":"2023 IEEE Conference on Power Electronics and Renewable Energy (CPERE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132028028","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}

On the other hand, excessive penetration of Distributed Generation (DG) systems into electrical networks may lead to several issues and operational limit violations, including over and under voltages, excessive line losses, overloading of transformers and feeders, failure of the protection system, and high harmonic distortion levels that exceed international standards. Many issues arise when the system goes above its Hosting Capacity (HC) limit. Without a system upgrade, the HC is a maximum solar system that is connected to the grid. This paper presents the methods for quantifying the solar PV hosting capacity of low-voltage distribution grids. Three fundamentally different methods are considered: i) deterministic ii) stochastic iii) time series. In addition, these methods are different in input data, output data, accuracy, time that can be used to obtain the desired output, and consideration of the time-related influence and the models used. Moreover, the present advantages and disadvantages of this method, and select the best method to find hosting capacity. The second objective of this paper present types of inverters controlled for the improvement of hosting capacity in low-voltage distribution grids, the inverters control such as reactive power control (Volt-Var) control, an active power control (Volt-Watt) control, combine active and reactive power (Volt-Watt & VoltVar).","PeriodicalId":169048,"journal":{"name":"2023 IEEE Conference on Power Electronics and Renewable Energy (CPERE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126391526","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 main electrical energy consumers in hot strip mill are the main six (or seven in some other plants) rolling stands and the coiler. However, auxiliary equipment cannot be neglected, as it accounts for approximately 25% of the total electrical energy consumed by the mill. Classical Static VAR Compensators (SVCs) are widely used in conjunction with Hot Strip Mills to regulate PCC bus voltage, improve system power factor and to reduce flickering when connected to (EAF). Production of higher carbon content steel grades, wide, and thin strips requires frequent higher reactive power that may exceed the designed VAR capacity of the currently installed SVC. There are two methods to overcome this challenge, the first method is to upgrade the capacity of the currently installed SVC by adding additional fixed capacitor banks (FC) and increasing the capacity of the Thyristor Controlled Reactor (TCR), the second method is to replace the TCR by a Static Synchronous Compensator (STATCOM). This paper presents the study of both methods and verification of results is carried out using MATLAB/SIMULINK.","PeriodicalId":169048,"journal":{"name":"2023 IEEE Conference on Power Electronics and Renewable Energy (CPERE)","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125730199","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}
