This paper proposes a model of Human to Nanogrid (H2N) that is based on the distributed generation technology to harness and store the human energy wasted during a workout on different gym equipment into a bank of supercapacitors. Targeted machines at the health club are selected based on the maximum load that can be lifted and also based on specific muscle group exercise that can be performed on them, such as bench press and Lat pulldown machine. Mechanical energy generated from a machine by different users over a period is studied and a comparison between the human power output and the energy consumption at the gym is carried out to find the change in monthly and yearly electricity bill. Finally, the collected data is utilized to analyze the energy savings, emission reduction and also the break-even analysis is performed to determine the payback period.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124418155","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}

Based on the elaborated analysis of PWM rectifier under unbalanced grid voltages, a new defined negative conjugate of complex power vector is as control variable, and the principle of selecting best voltage vector is deduced. Compared to LC-MPC based on conventional instantaneous power theory, the proposed strategy regulates the constant power references while no power compensation. Comparative study of the proposed method with conventional method is conducted under nonideal grid condition, and simulation results in the MATLAB demonstrate superior performance of the proposed LC-MPC strategy.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125361558","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 aspect of their optimal coordination is studied to assess transformer loss of life and hottest spot temperature (HST). Monte Carlo simulation is employed to provide synthetic data of EVs load in a residential complex and model their stochastic behavior. For load, temperature, energy price and PV generation, data for City of College Station, Texas, USA in 2018 is acquired and a case study is developed for one year.

The undispatchable nature of wind turbine generators (WTGs) causes the operating conditions of power systems to be more volatile. At the same time, the converter-based interface of WTGs are capable, and are increasingly expected to, provide voltage and frequency regulation capabilities. Monitoring of power systems becomes critical under these anticipated conditions and high resolution data, such as synchrophasors, are crucial for this task. This paper presents an approximate low-order model of WTGs that can be readily estimated from available synchrophasor measurements. The identification of the parameters of the model can be used to approximate the control performance of WTGs and their contributions to frequency and voltage regulation.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123037916","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}

Power utility companies use different software to calculate line impedances based on the conductor and structure types. However, the calculated values cannot remain accurate due to atmospheric condition. Also, due to lack of communication between the line construction, maintenance, and other departments, a line conductor/structure may be partially/totally changed without notifying the affected departments. Various estimation methods are used to dynamically obtain line impedance values. The majority of these methods use phasor measurement units (PMU s) for the impedances estimation. These methods require PMU s in the substations and fail to measure zero-sequence voltages/currents due to inadequate zero-sequence components under normal operation. The estimation of zero-sequence impedances is even more challenging for parallel transmission lines which are mutually coupled. This study proposes a method for estimating the self and mutual zero-sequence impedances for mutually coupled transmission lines using recorded fault data by protective relays. Extensive simulation results in RSCAD/RTDS indicate that the proposed approach has high accuracy in estimating the self and mutual zero-sequence impedances as well as the fault location in parallel transmission lines.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117269563","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}

Therefore, transformation and re-development of the island's grid system is of high interest. A key part of this re-development is the passing of an updated renewable portfolio standard (RPS), originally enacted in 2010, which states that by 2050 the energy needs in PR will be met entirely by renewable resources. The purpose of this paper is to determine the amount of renewable generation and energy storage necessary to meet these energy goals. An increase in renewable generation within any system poses several difficulties such as meeting night-time demand and handling the operation of the existing thermal fleet. A mixed-integer linear program optimization is formulated to identify the required investments in photovoltaic solar and energy storage to meet the RPS and to minimize the investment and operational costs. Within this RPS case study a sensitivity analysis is performed with different energy storage investment costs scenarios.","PeriodicalId":325598,"journal":{"name":"2020 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128232320","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}
