However, concurrent modeling and formulation of multiple services in grid management is a challenging problem. This paper proposes an energy management approach for microgrids including electrical and thermal forms of energy sources. The proposed approach takes advantage of battery storage devices for providing multiple services by applying chance-constrained optimization. The battery storage is deployed for 5-minute load following and energy arbitrage purposes. In addition, we have formulated a set of flexibility constraints, taking advantage of battery’s fast ramping capabilities, to enhance microgrid reliability in response to short-term solar power and load fluctuations. That is, the battery is deployed for load following, energy arbitrage, and regulation reserve procurement. Chance constraints are implemented to handle uncertainties of solar generation and load forecasting errors. Interdependencies between thermal and electrical energies are taken into account in the proposed approach. Numerical results show the effectiveness of the proposed approach to handle uncertainties, alleviate the short-term fluctuations, and enhance grid flexibility and reliability.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114649768","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 concept, magnetic flux between the inner and outer rotors is modulated through an array of magnetic pieces called the cage rotor. Despite the non-contact nature of magnetic gears in torque transmission, a minimal air-gap between the three rotors is required to achieve the best performance, which leads to more prerequisites in the design process, including bending analysis, thermal stress analysis, dynamic analysis, etc. Due to the fact that there are segmented magnets in a circumferential direction in the inner and outer rotors, as well as segmented pole pieces in the cage rotor, rotation of the gears causes oscillating forces in the active region. On the other hand, in order to increase the performance of the magnetic gearing system, steel bars in the active region are substituted with laminated stacks to gain stronger flow of magnetic flux throughout the system. The presence of the laminated parts is a potential candidate for failure under static and dynamic loads in the system, especially in long term system operation. Due to the lack of contact failure modes in magnetic gears, they are originally designed to be utilized in remote access applications, e.g. offshore, marine hydro-kinetic, and wind turbines, which require the longest operational life time. This demands fatigue analysis in all the critical parts under dynamic loads, specifically the laminated parts and rods holding magnetic components still. In this study, dynamic and fatigue analysis of a flux focusing multi stage magnetic gearbox is investigated through a multi-body dynamics and Finite Element Method, respectively.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116106383","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}

To reduce the computational burden associated with this optimization problem, distributed optimization is introduced. Since EVs randomly move from one bus to another bus, this paper proposes a temporal, rather than a geographical, decomposition approach to divide a ramp-constrained NCED. Thousands of EVs are considered over the scheduling horizon in order to take advantage of parallel computing and achieve reduced solution time. A ramp-constrained NCED is formulated for each sub-horizon while the connections between subproblems are modeled as shared variables/constraints. In order to coordinate the subproblems and find the optimal solution for the entire operation horizon, distributed auxiliary problem principle (APP) is proposed. Further, an efficient initialization strategy is presented to enhance the convergence time of the solution algorithm. The proposed method is employed to solve a week-ahead NCED on a 6-bus and IEEE 118-bus test systems. The results are compared with those of a centralized approach and effectiveness of the proposed method in reducing the solution time is verified.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123366413","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 switchgear and power cables, multiple PD faults may exist, which make the detection and location of such incipient faults challenging. This paper deals with identification of multiple PD faults by a hybrid detection technique, by combining conventional and unconventional measurement methods.Unconventional PD measurements rely on detection of physical emissions due to such faults, e.g. detection of radio frequency (RF) electromagnetic (EM) fields in the vicinity of PD activity, ultrasonic waves, optical emissions and heat produced by the PD, whereas the conventional measurement methods are based on detection of high frequency current and voltage, superimposed on the power frequency current and voltage.In this paper, the apparent charge of PD events is calculated by using conventional measurement technique and EM signal energy is calculated based on unconventional method. The high frequency electric field was measured using a D-dot sensor. The comparison between the two parameters show that a second degree polynomial relation exists between the EM energy and apparent charge. The scatter plots between the two variables show a number of patterns due to the number of PD faults. Therefore, the detection of multiple faults is possible.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128340777","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}
