This creates the need for both active and reactive power support systems at the Common Coupling Point (CCP) of a renewable power generating station. Considering the aforesaid requirements, a distinct configuration using a Modular Multilevel Converter (MMC) with Hybrid Storage System (HSS) has been recommended in this paper. These kinds of systems are termed as “Statcom Embedded with Storage System”(SESS). The SESS helps to pump invariable power into the grid by absorbing fluctuating components of active power generated by the renewable power generating plant. Apart from this, provides ancillary services at CCP like, voltage regulation and compensation for negative sequence currents, and ride through capability during the faults in the ac system are to be provided by SESS. The required control methods to operate the proposed configuration for the aforesaid necessities are discussed in this manuscript. The economic advantage of the proposed configuration in comparison to other multilevel topologies has been identified using a techno-economic study and it is presented. The competency of the recommended configuration for SESS application along with its control is verified through PSCAD/EMTDC simulation and the results show its efficacy.","PeriodicalId":13252,"journal":{"name":"IETE Technical Review","volume":"40 1","pages":"380 - 396"},"PeriodicalIF":2.4,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44661562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, they inject harmonics into the power system. To deal with the problem, the use of filters has become almost inevitable. Active power filters controlled by direct power control (DPC) have overtaken this responsibility from the passive filters because of their numerous advantages. To deal with the real-world power system grid which is far from the idealized character of being balanced and sinusoidal, the proposed method uses the extended pq theory integrated with the dual second-order generalized integrator (D-SOGI) for the correct estimation of the all-important instantaneous powers. In contrast, the conventional pq theory is used in the existing works, which doesn’t hold in a non-ideal grid. In addition to that, here, for the selection of the switching vector, an advanced and more accurate predictive DPC method which is specifically designed to operate in a non-ideal grid, replaces the static look-up tables used in the previous works. Further, to make the filter designing easier, the proposed method focuses on constant switching frequency operation eliminating the problems arising from variable switching frequency used in literature. The proposed technique is tested in MATLAB/Simulink environment and the real-time system to validate its feasibility.","PeriodicalId":13252,"journal":{"name":"IETE Technical Review","volume":"40 1","pages":"521 - 534"},"PeriodicalIF":2.4,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43879247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Partial Shading (PS) significantly contributes to power loss in LSBA. One effective solution to mitigate the adverse effect of PS in LSBA is the application of fixed or static BIPV array configurations (BIPV-ACs). This research article critically compares the different fixed BIPV-ACs for modelling, designing and critical analysis of LSBA. Different existing and proposed fixed BIPV-ACs are modelled and simulated in MATLAB/Simulink under six dissimilar cases of PS patterns. Further, the performance is investigated in terms of global maximum power point (G-M-PP), mismatch loss (ML), fill factor (FF), efficiency (η), relative power loss (RPL) and relative power gained (RPG) to identify the best BIPV-AC. Experimental justification of simulation results under two PS pattern cases is reported. The best BIPV-ACs with high G-M-PP and low ML are Total-Cross-Tied (TCT), Triple-Tied (TT), Modified Triple-Tied (M-TT) and Hybrid Bridge-Linked Total-Cross-Tied (H-BL-TCT). Finally, the comprehensive critical analysis reveals that the H-BL-TCT array is the best performing array with low ML, high FF and η, and high G-M-PP with low wiring requirements than the TCT array. The simulation results conclude that the H-BL-TCT array improves G-M-PP by 6.40 %, reduces ML by 4.23 %, and improves FF & η by 4.58 % and 0.54 %. The experimental results infer that the H-BL-TCT array improves G-M-PP by 0.83 %, reduces ML by 0.75 %, and improves FF & η by 0.88 % and 0.09 %.","PeriodicalId":13252,"journal":{"name":"IETE Technical Review","volume":"40 1","pages":"465 - 497"},"PeriodicalIF":2.4,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48759142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sentences of the input set of documents are represented by the nodes of the network. Weighted edges are added between the nodes to represent the semantic similarity between the corresponding sentences. The network has a multilayer structure, where each layer corresponds to an individual input document. This helps in effective differentiation between the inter-document and intra-document edges. A hyperparameter, namely layering factor, has been used to alter the strength of inter-document connections through reinforcement or weakening. It is hypothesized that the summary sentence nodes must act as effective information spreaders in the sentence network. Summary generation is performed by identifying the influential nodes of the network using VoteRank scheme. A comparative study with different network measures, such as Weighted Degree, PageRank, Betweenness centrality, and Closeness centrality reveals the efficacy of the proposed VoteSumm technique for multi-document text summarization. Improved performance is observed when an additional pre-processing step of syntactic simplification is applied on the raw text. Performance is further improved when keyword information is included in the simplified texts.","PeriodicalId":13252,"journal":{"name":"IETE Technical Review","volume":"40 1","pages":"535 - 548"},"PeriodicalIF":2.4,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44264337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
