Investing in the technology, however, is not enough to ensure the widescale replication and adoption of smart city technologies necessary to achieve decarbonization goals. Commonwealth Edison (ComEd), the electric utility serving over 4 million customers in northern Illinois, including Chicago, is building strategic partnerships in academia to measure the impact of resilience efforts. This paper will explore partnerships ComEd has developed with the National Center for Disaster Preparedness (NCDP) at the Earth Institute of Columbia University and Lawrence Berkeley National Laboratory (LBNL) to study the impacts of emerging energy technology for widescale replication worldwide. Electric utilities must go beyond investment in smart grid technology. Studying, sharing, and modelling best practices through strategic partnerships is a necessary part of investment in emerging energy technologies to benefit rate payers and stakeholders.","PeriodicalId":127126,"journal":{"name":"2021 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131946416","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 study is carried out in the context of Pakistan, a country that has been struggling with energy crises for a very long time. Previously, it has been shown that a CSP plant in Pakistan is a feasible option. This paper aims to find an optimal combination of nanoparticles and molten salt for a CSP plant in Pakistan. The selected site Nara desert, Nawabshah in the province of Sindh receives an annual direct normal irradiance of 1955 kWh/m2. A 100 MW Parabolic Trough Collector (PTC) plant is modeled using the System Advisor Model (SAM) and is integrated with thermal energy storage of up to 10 hours. The model is validated by comparing results with commercial-scale plants. From literature, nanoparticles with the highest share of usage in performance enhancement of PTC collectors (CuO, Al2O3, and TiO2) with different fractions are selected and Hitec Solar Salt is considered as the base fluid. Parametric optimization is carried out for each of the working fluids. The performance is compared based on annual power generation, capacity factor, plant efficiency, and required Thermal Storage volume. The comparison shows that by using nanofluids, the annual power generation, capacity factor, and efficiency are increased by 8.86%, 8.88%, and 8.9% respectively, whereas the volume of thermal storage is reduced by 36.02%. The optimal fraction of nanoparticles is found to be 1%, 2%, and 5% for CuO, Al2O3, and TiO2, respectively.","PeriodicalId":127126,"journal":{"name":"2021 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114068597","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}

This research seeks to contribute to the limited research-based understanding of the dynamic, and potentially harmful relationship between sediments and water quality. To fill the gap, this study utilized the Hydrologic Engineering Centre-River Analysis System (HEC-RAS) model to forecast the river’s sediment volume and water quality from the period of January 2020-2021 using average weather flow under existing river geometry and characteristics. Additionally, water samples collected from three stations of the river were used for the analyses. This research has found that significan sediment volume will accumulate in the river, BOD will also increased, and the DO on the other hand decreased by the end of the year. Statistical analyses have also revealed a strong inverse relationship between the DO and the cumulative sediment volume; and a weak direct relationship between the cumulative sediment volume and the BOD. A potential increase in sediment volume will be particularly significant in the river's outlet based on the projection made which suggests that the Naic River might receive high amounts of pollutants. Furthermore, there was a strong agreement between the actual data and the HEC-RAS predicted data — which accounts for the efficiency of the method used in the study. Finally, because its water quality falls short of DENR's standards, this research confirms that the river is polluted. The results of this study may be used for close monitoring of the parameters that cause degradation of the water quality in the river. Various engineering solutions such as decentralized wastewater treatment and sustainable sediment management strategies are suggested to improve river water quality.","PeriodicalId":127126,"journal":{"name":"2021 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123526690","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 condition assessment of watermains is one of the key strategies that can pinpoint risky pipes and maintain their sustainability. Intelligent systems such as fuzzy inference system (FIS) and adaptive neuro-fuzzy inference system (ANFIS) have proved their efficacy in simulating and predicting intricate water infrastructure problems. This research paper proposes a novel methodology for the development of a risk scale, along with the evaluation and quantification of water network’s condition index. The Arequipa region in Peru that comprises eight provinces is chosen to demonstrate the proposed methodology due to the fast pace of urban sprawl, as well as the economic boom that make sustaining underground pipelines a difficult task. The methodology builds on various algorithms, computational intelligence and interactions between different variables. It involves developing two intelligent models; the first is the ANFIS model that is designed to estimate the watermains condition index of each province through the grid partitioning and hybrid optimization function. Several neuro-fuzzy networks are created and tested through different statistical indicators to select the optimal network that can be used to predict the condition indices of each province. The produced condition indices are then streamlined and entered into the FIS engine to develop the second (FIS) model, which is built on the basis of Mamdani system. The FIS engine runs an iterative simulation process through which the input variables are fuzzified, fuzzy rules are evaluated, outputs are aggregated, and results are de-fuzzified. Finally, the fuzzy consolidator generates one crisp number that represents the water network condition index of the region. The resulted risk scale indicates that the condition of water distribution networks of the Arequipa region is medium, in accordance to the questionnaire of professionals and field experts. This research provides insights for infrastructure managers concerning their maintenance, replacement or rehabilitation plans.","PeriodicalId":127126,"journal":{"name":"2021 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127744055","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}

New insights make a case for using resiliency metrics instead of traditional reliability metrics to direct investments designed to harden the grid. The data also underscores the growing importance of the role of external stakeholders including regulators and the general public in setting priorities as we match the capabilities of an increasingly responsive grid to an increasingly dynamic risk environment. While there are key differences between the impact of the COVID-19 pandemic on utility operations and the grid versus the typical impact of weather-related events, a grid that is more resilient to weather-related events also provides resilience during a pandemic. The timeline to a post-pandemic normal is still unknown, but utilities can leverage the economic recovery that will follow the current economic recession to build a more resilient and sustainable grid with the support of analytic tools, models and metrics that enable dynamic grid operations and investment that address immediate and longer term risks.","PeriodicalId":127126,"journal":{"name":"2021 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"365 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121657901","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 networks are known to be nonlinear, dynamic, and involve a multitude of influential factors that cannot be measured accurately in any conventional metrics. In general, deterioration factors obtained from field inspections reports or from experts’ survey have certain degrees of ambiguity and subjectivity. One of the potent methods that have emerged in the last four decades to solve civil infrastructure problems, is the fuzzy inference system (FIS). This method can encode the deterioration factors into risk indices while coping with the inaccuracy, ambiguity, and fuzziness of data. The objective of this paper is to develop a risk index model for water transmission pipes based on simulation and FIS. First, the input and output datasets of the proposed model are defined based on inspection reports and experts’ questionnaire; both the input and output datasets are fed into the FIS engine.

It is a reliable solution for overcoming the inefficiencies and mismanagement in a power system. Due to the increased power consumption, the current electric power system is experiencing grave operational challenges and as a result, the transmission line blackouts occur occasionally. The paper presents and analyzes a microgrid system based on RES with a focus on the smart use of demand and generation in a microgrid. In the proposed system, power sources are scheduled as per requirement and the loads are categorized as critical and non-critical loads. The power to the critical load must always be maintained therefore, in a critical situation the power to the non-critical load is shed off to make the critical load running. Moreover, the load management is done by using the Demand Side Management (DSM) technique, in which load is shifted from peak hours to off-peak hours. The proposed system is simulated in MATLAB and a prototype has also been developed. The results indicate the smart supply to the critical and non-critical loads as per the defined conditions and availability of the power sources.","PeriodicalId":127126,"journal":{"name":"2021 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132713891","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}
