However, high-speed data streaming challenges the quality of communication and data server storage. To address this problem, this paper proposes an online lossless compression of synchro-waveform measurement for smart grid monitoring. The lossless compression will highly reduce the data transmission and storage burden while reserving all the critical information for both online and offline analysis. To this end, the proposed method is designed based on the delta-delta, Simple-8b, and Lempel-Ziv-Markov chain algorithm technologies, where the delta-delta consists of a two-order delta and one periodical delta. Then, the simulation experiments based on various noise levels, time windows, and sampling rates are presented and compared with some state-of-art methods. Moreover, the laboratory experiment is conducted to verify the validity of the synchro-waveform measurement compression method, where 53.1% to 77.3% of data space can be saved under 60dB to 120dB noise scenarios.","PeriodicalId":69792,"journal":{"name":"中东研究","volume":"105 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74977607","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 this study, we examine the effect of utilizing smart inverters for reactive power support, assess potential impact of this use case on the battery lifetime and State of Charge (SoC), and institute corrective action to mitigate degradation. Initial analysis showed that filter design on the DC side plays a crucial role in reducing current flow in the battery (which impacts the SoC). As a remedial measure, an inductor filter has been tested on both the DC side (between the battery and inverter) and AC side (between the inverter and grid) to reduce the battery current and keep the total harmonic distortion of the system within acceptable limits respectively. The results show that with the proper alteration of the BESS set points, i.e., regulating the bus voltages, will enhance the stability of the system. Furthermore, during intervals when there is no real power flowing to/ from the BESS (and only reactive power is being inject/absorb), the battery current is zero. This demonstrates that with proper filtering BESS can provide VAR support without impacting its lifetime.","PeriodicalId":69792,"journal":{"name":"中东研究","volume":"10 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87823966","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 simultaneous charging of a large number of electric vehicles could overload the grid. To solve this problem, sensors must be used to create observability of the low-voltage grid and to introduce control of the charging processes. The new sensors will generate large amounts of data containing personal information. For better and local handling of these data streams, edge computing approaches have been discussed. In this work, an edge computing system for the problem is presented. The structure of the software and the LoRa-based communication system is discussed in particular. Different sub-tasks are packaged in docker containers to get flexible and reusable software, that can be used for multiple use cases and hardware systems. The LoRa communication should lead to higher data security with it being decentralized and independent of the internet. With the system presented here, it is possible to determine the grid state using the sensors installed in the grid and to use this information to control the charging process of electric vehicles. The system was tested in a field test. The results show the general applicability of the approach and needed improvements for LoRa communication.","PeriodicalId":69792,"journal":{"name":"中东研究","volume":"6 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80146940","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 high active power requirements increase the cost and the size of an energy storage system (ESS) associated with the DVR. Some existing control schemes rely on decreasing the cost of phase jump mitigation by reducing the active power requirements either by limiting the injected voltage or using an optimization tool to optimize ESS energy sharing. In this paper, a control scheme is proposed to provide voltage transients compensation which relies on a phase jump mitigation in the load voltage using a phase angle transition mechanism. The proposed scheme increases the DVR compensation time by 50% compared with existing phase jump compensation approaches. For the same compensation time, this modification can be translated into a significant reduction in dc link capacitor size. The proposed scheme for voltage compensation is tested for different types of supply voltage transients, including voltage sag, harmonics injection, and balanced and unbalanced short circuit cases. The proposed scheme is validated using the MATLAB/Simulink simulation platform.","PeriodicalId":69792,"journal":{"name":"中东研究","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82026774","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 proposed configuration has reduced number of devices and components as compared to the conventional three-phase bridgeless (BL) Zeta converters. Further, the combination of this new configuration with the interleaving and discontinuous conduction mode (DCM) offers a compact design for on-board charger. DCM operation ensures the benefits of inherent zero current switching of switches and diodes. Moreover, the size of magnetics is significantly reduced and sensing requirement is less, as compared to CCM (Continuous Conduction Mode) operated converters. This is due to absence of PLL in the control circuit, as DCM provides natural power factor correction at input. Therefore, the size of converter is significantly reduced due to less sensing requirement, smaller magnetic components and fewer number of power devices. The proposed BLIL converter is designed and simulated in MATLAB/Simulink environment for 3.1 kW rating and to charge a 200V, 50Ah Li-ion battery. The charge time for the battery is estimated to be 3-4 hours approximately.","PeriodicalId":69792,"journal":{"name":"中东研究","volume":"65 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88390490","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}
