Within this context, a novel approach to the integrated formulation of the natural gas and electric power flow problem is proposed in this paper. This formulation is developed in a single frame of reference that allows an integrated energy flow analysis. Contrary to the current proposals for performing this type of analysis, the generator-governor characteristics, as well as the voltage and frequency dependence of loads, are incorporated into the system of equations of the electric power flow problem. This permits a better representation of the interaction between both energy infrastructures and of their actual operating conditions. The applicability of the proposed approach is demonstrated by analyzing an integrated multi-energy system composed of the IEEE 118-bus electrical system and a 15-node natural gas infrastructure.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126408406","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}

Distribution companies have corporate supervisory, control, monitoring, georeferencing and management systems and have invested in automation and modernization projects of their electric grids for this purpose. Thus, this paper presents an approach for the development of a DMS – Distribution Management System, for Advanced Distribution Automation (ADA) applications, which includes state estimator, Volt/VAr control, fault location, isolation, and self-restoration tools, so that an interoperability bus (BCIM) integrates the corporate systems with the operational management. The developed applications were tested for real networks, in a computational environment, and integrated with the environment of the NAPREI / USP Smart Grids laboratory. The results demonstrate the processes of integrating ADA applications into a commercial service bus, which communicates the company’s legacy systems, of testing their applications, and its challenges.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129026487","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}

EMS simulations are usually performed at the planning stage and by system operators using phasor methods to accelerate the analysis of very large systems under several fault contingencies. EMT analysis is performed with very detailed models and small integration steps to simulate fast transients and control dynamics. Determining the risk of multiple HVDC commutation failures and the resulting power transfer capability of large multi-infeed HVDC inverter systems would normally require performing EMT simulation using detailed HVDC controller models. However, using traditional singleprocessor EMT software is normally not practical to analyze the EMS of large systems with several HVDCs due to the long calculation times. This paper analyzes the performance of parallel EMT software to analyze the transient stability of practical and large AC/DC systems using standard multi-core computers. It will be demonstrated that a simulation speed of two real-time speed can be achieved with a reasonable number of processors, even for a system as large as the Brazilian grid.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115419885","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}

So, this paper presents the ranking of customer buses supplied in Low Voltage (LV) in order to install lithium BESS in DG plants based on PV systems, under a R&D project, whose goal is to study the impact of BESS in urban DS feeders. The bus ranking and BESS allocation problem was solved through Analytic Hierarchy Process (AHP), because this technique allows to evaluate the alternatives computing technical criteria related to electrical magnitudes, and subjective criteria related to customer aspects. The main contributions achieved were the model from the hierarchical structure of BESS allocation problem, the weights obtained with adapted pairwise analyses resulted of specialists evaluation which reduces Saaty scale complexity, and the LV-customer-buses ranking for three different scenarios.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115958470","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 analyzed methodology applies the multiProny method by area and integrates local modal estimates in a consensus optimization process that determines a global solution for the entire system. In each area, multiple measurements are processed corresponding to ringdown data, recorded in case of contingencies by PMUs (Phasor Measurement Units) of a WAMS (Wide Area Monitoring Systems). The distributed method of optimization and consensus used here is based on the distributed ADMM (Alternating Direction Method of Multipliers) algorithm. The performance of the distributed Prony method is evaluated by processing known analytical signals and synchrophasorial voltage measurements recorded at low voltage by the MedFasee BT Argentina Project: Observatory of the Dynamics of the Sistema Argentino de Interconexión (SADI). The results show that more precise oscillatory modes are obtained with the distributed multiProny method than with the simple Prony method when processing a single signal or a set of signals in a centralized way.","PeriodicalId":448644,"journal":{"name":"2020 IEEE PES Transmission & Distribution Conference and Exhibition - Latin America (T&D LA)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131802600","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}
