In this paper, the impacts of adding renewable resources and changing generators’ voltage regulating buses on static power flow convergence and voltage profiles are studied and reactive power status of critical areas as well as online and offline reactive power reserve capacities are visualized. The results show that if renewable resources are added without adding sufficient reactive power resources or if the voltage regulating bus of all generators move to the low voltage side of step-up transformers without tuning the voltage set points of generations, voltage violations and even voltage collapse may occur, which have a negative impact on the reliability of the power system. The paper also reviews possible solutions such as tuning the voltage set points of generators for reactive power management and adding voltage control devices such as switched shunts or static var compensators (SVCs) to the grid to compensate for this change.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"13 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":"115056914","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}

ACE is used to correct the generation dispatch to compensate for frequency deviation. ACE also indicates the required power export or import in an interconnected power system. Unlike wind and solar power prediction, there has been no work to forecast the ACE in the power system. For an interconnected extensive transmission system, the ACE is considered a volatile time-varying signal. For an accurate ACE prediction, this work represents a deep learning-based forecasting model. The model decomposes the ACE signal using the discrete wavelet transform (DWT) and utilizes the bidirectional long short-term memory (BiLSTM) for the prediction. The proposed forecasting technique is trained to capture the deep temporal features of the signal with higher accuracy when compared to other methods. Two ACE datasets with sample times 1-minute and 10 minutes are predicted. The real data is gathered from Pennsylvania, New Jersey, and Maryland interconnection (PJM), USA. To evaluate the proposed technique, it is compared to other benchmark forecasting networks.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"1 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":"115780579","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}

Single-stage SSTs can be of significant interest in these grids because they employ fewer passive components besides offering a simpler power flow control. In this paper, a closed-loop feed-forward PQ controller is investigated for a single-stage bidirectional ac-ac SST that consists of two H-bridge cells and a high-frequency transformer in a dual active bridge (DAB) configuration. Single phase-shift PWM is used to meet the active and reactive powers demands of the single-phase ac grids. A second-order generalized integrator (SOGI) in conjunction with a phase-locked loop (PLL) ensures proper grid synchronization. The operation of the controller is validated through simulations performed on a 3.6 kVA, 120/120 V SST. With the designed controller, the SST can meet 20% of its rated kVA as reactive power without exceeding the maximum allowable total harmonic distortion (THD) injection to the grid as per the IEEE 519-2014 standard.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"8 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":"128829950","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}

However, the success of data-driven algorithms such as machine learning algorithms heavily depends on the availability of SG data. Currently, SG data mostly stay with the data generators such as utilities, market operators and system operators. The flow of SG data among various stakeholders is currently limited due to the lack of a proper data exchange platform. Recently, the concept of data markets for SGs has been introduced to address this issue. However, the success of data markets in SGs heavily depends on the large-scale participation of the various stakeholders. So, there is a need to understand the opinion of the stakeholders on various aspects of SG data markets. This paper presents the results of an online survey that was conducted in order to investigate the feasibility of data trading in SGs. A comprehensive analysis of the survey responses is also presented. It is found that the majority of the survey participants support the formation of data markets in SGs to increase the accessibility of practical SG data. However, a section of the participants raised concerns regarding privacy, grid security and money availability. The results of this survey will be helpful in deciding future research directions in this area.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"463 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":"127005485","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}

Wave Energy Converters (WECs) are a technology being developed to extract the energy from the ocean efficiently and economically. The main components of a WEC include a buoy, an electric machine, an energy storage system, and a connection to the onshore grid. Since the absorption of the energy in the ocean’s waves is a complex hydrodynamic process a power-take-off (PTO) mechanism must be used to convert the mechanical motion of the buoy into usable electric energy. This conversion can be done by using a rack-and-pinion gear system to transform the linear velocity of the buoy into a rotational velocity that is used to turn the electric machine. To extract the most energy from the ocean waves a controller must be implemented on the electric machine to make the buoy resonate with the frequency of the waves. For irregular wave climates a multi-resonance controller can be utilized to resonate with the wave spectrum and optimize the power output of the WEC.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"4 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":"132261902","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}
