The interconnection between different components in a power system causes failures to easily propagate across the system. The situation gets worse by considering the interconnection between cyber and physical layers in power systems. A plethora of work has studied the cascading failure in power systems to calculate its impact on the system. Understanding how failures propagate into the system in time and space can help the system operator to take preventive actions and upgrade the system accordingly. Due to the nonlinearity of the power flow equation as well as the engineering constraints in the power system, it is essential to understand the spatio-temporal failure propagation in cyber-physical power systems (CPPS). This paper proposes an asynchronous algorithm for investigating failure propagation in CPPS. The physics of the power system is addressed by the full AC power flow equations. Various practical constraints including load shedding, load-generation balance, and island operation are considered to address practical constraints in power system operation. The propagation of various random initial attacks of different sizes is analyzed and visualized to elaborate on the applicability of the proposed approach. Our findings shed light on the cascading failure evolution in CPPS.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"30 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89546156","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 hybrid compensator constitutes of Thyristor Switched Capacitor (TSC), Thyristor Controlled Reactor (TCR), a lower rating D-STATCOM and a 5th harmonic tuned passive LC filter. The Static var Compensator (SVC) or the TCR-TSC combination works in a coordinated way for the base var compensation. The D-STATCOM works in a coordinated scheme with the SVC and the single tuned LC filter to compensate fundamental var, reduce voltage flicker and also attenuate harmonic currents at the Point of Common Coupling (PCC). The D-STATCOM thus serves a dual role as a var compensator and as an active filter in Selective Harmonic Compensation (SHC) mode to attenuate the 7th harmonic current, hence improving the var compensation and harmonic current filtering at PCC. The proposed hybrid configuration exhibits very low line current THD in accordance with the relevant standards. Also the chance of resonance of the fixed passive filter with the source inductance has been eliminated in the coordination scheme. The simulation results show that the proposed hybrid system compensates var, reduces voltage flicker and harmonic currents at the PCC effectively. The proposed control and coordination scheme is simple to execute besides the hybrid system being highly robust in performance.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"87 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81278909","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}

This optimized consumption plays a vital role in resolving the complex operation and reliability issues in the electricity market. The human behaviour aspect of consumers explained by several models that have been reported in the literature. These models depend on the classical utility factor. The effect of price on the consumer’s decision in the field of energy efficiency and reduction of consumption based on behavioural characteristics are two important aspects of DR programs. In absence of such characteristics, results become non-viable. In this paper, the footprint of two time-based DR programs is explored on the peak reduction namely; Real Time Pricing (RTP) and Peak Time Rebate (PTR). Artificial Neural Network (ANN) based topologies for two DR programs are proposed. The proposed topologies employ variation in demand and price, subsequently for simulating an online DR simulator. Demand before and after the RTP and PTR were calculated and compared with four ANN based DR topologies namely; Radial Basis Function Neural Network-Demand Response (RBFN-DR), Feedforward Backprop-Demand Response (FFBP-DR), Layer Recurrent–Demand Response (LR-DR), and Generalized Regression-Demand Response (GR-DR). The proposed models are tested on hourly residential data of test smart grid. By assessing the results from test case, depicted that RBFN-DR proved its efficacy by giving better results for both price-based programs namely; RTP and PTR.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"26 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81540010","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}

Self-excited induction generators (SEIGs) are preferred for wind energy conversion systems because they are simple, low-cost, and durable. It is vital to get comprehensive insights into an induction generator’s dynamic behaviour to develop an effective control system governing its voltage, frequency, and reactive power. This study analyses the performance of two non-linear models of an asymmetrical six-phase SEIG using stator and rotor currents as state variables. The mathematical models of SEIG differ in terms of the presence or absence of a dynamic cross saturation effect. Transient events, including voltage build-up, sudden load perturbation, and unloading of the six-phase SEIG, reveal substantial performance variations between the studied modeling approaches. When comparing the full model (which contains the cross-saturation effect) to the simplified model, the full model shows a faster steady-state convergence. Experimental and simulated results are presented to support arguments.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"42 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85084890","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 $mathrm{N}mathrm{E}mathrm{I}_{mathrm{o}mathrm{i}1}$ and $mathrm{N}mathrm{E}mathrm{I}_{mathrm{p}mathrm{a}mathrm{p}mathrm{e}mathrm{r}}$ are derived from real time dissolved gas analysis data of in-service transformer and reactors having age more than a decade. Considering the positive correlation and goodness-of-fit, Gumbel copula is found to be most suitable for modeling the bivariate joint distribution. Results of the copula model indicate that for an increment of $0.5mathrm{k}mathrm{J}/mathrm{k}mathrm{L}$ in $mathrm{N}mathrm{E}mathrm{I}_{mathrm{o}mathrm{i}1}$ there is an increment in $mathrm{N}mathrm{E}mathrm{I}_{mathrm{p}mathrm{a}mathrm{p}mathrm{e}mathrm{r}}$ between 1.0 and $2.2mathrm{k}mathrm{J}/mathrm{k}mathrm{L}$. It demonstrates the importance of considering $mathrm{N}mathrm{E}mathrm{I}_{mathrm{p}mathrm{a}mathrm{p}mathrm{e}mathrm{r}}$ in addition to $mathrm{N}mathrm{E}mathrm{I}_{mathrm{o}mathrm{i}1}$ for assessing the fault severity and evaluating the internal condition of liquid and solid insulation of transformer and reactor. The study undertaken will help in monitoring, maintenance, and conditioning assessment of the equipment based on the NEI values, which will further help in saving unprecedented failure of in-service transformer and reactors.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"25 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85585427","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}
