The microgrid has a capability to be operated in both grid-connected and island (off-grid) modes. The microgrid supplies its own load while it is equipped with an energy storage and a wind turbine as a renewable energy source. Herein, fuzzy approach is used in MILP to address the uncertainty issue of the renewable’s power. It is demonstrated that the application of fuzzy MILP can remarkably decrease the operation cost of the microgrid. Moreover, it is shown that the fuzzy MILP is robust to the inaccurate prediction of the uncertain parameter of the problem.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"374 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134326247","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}

These sources not only help in providing voltage and frequency reference for other inverters but also mimic the inertia of the synchronous generator. This paper proposes a control strategy for emulation of virtual inertia in inverters operating in islanded operation mode. A delay based control strategy is implemented and by varying the inertia constant it mimics the performance of a synchronous generator. Finally, to verify the above statement, similar loading is done on a synchronous generator with similar inertia constants and compared with the proposed grid forming inverter. Transient response parameters are compared in both the cases using EMTDC/PSCAD.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127317536","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 paper utilizes the Iterative Matrix Pencil Method (IMP) to determine the most significant electro-mechanical modes and their associated mode shapes after the system has been perturbed by generator or load outage contingencies. The paper shows that the resultant values can be dependent on both the applied contingency and the set of signals used in the IMP with this sensitivity due at least in part to the system nonlinearities. The techniques are demonstrated using three synthetic grids ranging in size between 2000 and 70,000 buses. Visualization methods are used to show the mode shapes and compare and contrast how modes manifest themselves on the grid.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130004498","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 paper, the economic feasibility of DWPT is evaluated for major highways in the state of Indiana using a levelized cost metric.

The converter consists of two series connected transformers. The leakage inductances are utilized as LLC circuit components, forming the resonant series inductance while the other is the magnetizing element of each transformer, the external capacitance is added to complete the LLC circuit structure. One of the transformers is used to inject voltage into the LLC network to enlarge the voltage gain, while the other operates as a regular LLC converter transformer. The proposed topology presents multiple advantages: 1) high voltage gain is achieved with reduced switching frequency range, 2) higher efficiency at higher voltage gains. The simulation results proved that the converter achieved high efficiency over a wide range of voltage gain using the adopted strategy.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128125452","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}

Electric machines like the induction motor (IM) and permanent magnet synchronous motor (PMSM) have stationary frame models with sinusoidal states: currents, fluxes or EMFs. Sliding mode observers constructed based on these models use switching terms that sometimes need to be filtered in order to obtain the equivalent controls: they are needed for subsequent processes like calculations or estimation. These can be obtained based on simple low pass filtering; however, this method is not accurate and affects the performance of the downstream processes. The paper presents three methods that allow to obtain accurate equivalent controls. The methods can be used when the expected equivalent controls are a pair of sinusoids 90 degree out of phase. The methods presented require knowledge of the operating frequency - this is estimated using a phase locked loop.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130363290","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 scope includes determination of converter ratings, device selection, other component selection, PCB layout and testing. The converter ratings are determined based on the design of AMB and an estimate of the residual mass unbalance in the high-speed rotor to be supported.

A harmonized automatic relay mitigation of nefarious intentional events (HARMONIE) special protection scheme (SPS) is being developed to address that need. However, for evaluating the HARMONIE-SPS performance in classifying system disturbances and mitigating consequences, a cyber-physical testbed is required to further development and validate the methodology. In this paper, we present a design for a co-simulation testbed leveraging the SCEPTRE™ platform and the real-time digital simulator (RTDS).
