Thus, in this work where an ultrafast mechatronic circuit breaker (UFMCB) is implemented in real-time on the field-programmable gate array, a detailed nonlinear thyristor model is proposed for extra device-level information regarding design evaluation. The cascaded thyristors impose a heavy computational burden on the UFMCB simulation, and node elimination is achieved following the proposal of a scalable thyristor model. For the convenience of the circuit breaker’s integration into DC grid, a pair of coupled voltage-current sources is inserted as its interface, which achieves a reduction in the dimension of system admittance matrix, and the subsequent proposal of a relaxed scalar Newton-Raphson method further expedites the simulation by decomposing the nodal matrix equation. Meanwhile, the modular multilevel converter as a DC grid terminal adopts half-bridge and clamped double submodule topologies to test system performance in conjunction with the UFMCB. Realtime execution is achieved and the results are validated by ANSYS/Simplorer and PSCAD/EMTDC in device- and system-level, respectively.","PeriodicalId":106476,"journal":{"name":"2020 IEEE Power & Energy Society General Meeting (PESGM)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129843497","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}

Contingency-constrained unit commitment (CCUC) satisfying the “N – 1 rule” is extremely complex, and the complexity is now compounded by the drastic increase in renewables. This paper develops a novel interval optimization approach for CCUC with N – 1 transmission contingencies and renewable generation. A large number of transmission contingencies are innovatively described by treating corresponding generation shift factors (GSFs) as uncertain parameters varying within intervals. To ensure solution robustness, bounds of GSFs and renewables in different types of constraints are captured based on interval optimization. The resulting model is a mixed-integer linear programming problem. To alleviate its conservativeness and to further reduce the problem size, ranges of GSFs are shrunk through identifying and removing redundant transmission constraints. To solve large-scale problems, Surrogate Lagrangian Relaxation (SLR) and branch-and-cut (B&C) are used to simultaneously exploit separability and linearity. Numerical results demonstrate that the new approach is effective in terms of computational efficiency, solution robustness, and simulation costs.","PeriodicalId":106476,"journal":{"name":"2020 IEEE Power & Energy Society General Meeting (PESGM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129880958","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}

A deeper analysis of AC Circuit elements is also presented with statistically significant findings regarding voltage class, outage initiation code, outage mode code, initiating cause code, and outage duration.

VSC based on their control mechanism can be categorized as line-frequency switched and pulse width modulation converters. The line-frequency switched VSCs are based on angle-control method and hence also referred as angle-controlled VSCs. Over the past few years, angle-controlled STATCOMs have been deployed by the utilities for the purpose of voltage regulation and stability and to improve transmission capacity. Apart from the advantages offered to increase voltage transient, the on-site STATCOMs suffer from over-current trips and DC bus voltage oscillations under system faults. The negative sequence current during the faults tend to trip the overcurrent protection and possibly saturation of the interfacing transformer. It also leads to second order harmonic oscillations of the DC bus voltage which can trigger over-voltage protection. Dual angle control (DAC) is a control methodology that generates angle oscillations control signal during system faults which reduces the negative sequence current flow and dc-link oscillations compared to conventional angle controlled STATCOMs. The procedure was effective but deals with complexity of calculating the reference signal for angle oscillation. This paper proposes a simplified dual angle control based on DC-link voltage oscillation. The main advantage over the DAC is its simplified control structure, without compromising the performance in reduction of the negative sequence current and DC-link oscillations. Since the dual angle control is based on DClink voltage oscillation and hence it is called DC-link based dual angle control (DC-DAC). PSCAD/EMTDC results for 48-pulse STATCOM connected to a three-bus power system verify the validity of proposed DC-DAC control under unbalanced system condition and faults.","PeriodicalId":106476,"journal":{"name":"2020 IEEE Power & Energy Society General Meeting (PESGM)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130161651","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 sense, the power converters participate in the conditioning and control of the power delivered by the generators, requiring an analysis of the impact caused by situations that lead to possible damages or lifetime shortening due to abnormal operations. Considering this problem, in this paper a case study is performed in order to evaluate the impact of the double fed induction generator (DFIG) low-voltage ride-through (LVRT) on the switches of the back-to-back converters. For this purpose, modeling of the DFIG-based WECS has been performed in MatLab/Simulink, including a linear model for the converter switches, which are of insulated gate bipolar transistor (IGBT) type. The analysis presents the main impacts on the IGBT internal currents and voltages under symmetrical and asymmetrical grid faults, making possible to guide the application of methods and techniques to minimize the impacts caused to the converters.","PeriodicalId":106476,"journal":{"name":"2020 IEEE Power & Energy Society General Meeting (PESGM)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126972428","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}
