The power system analysis tools should harmonize the new technologies in a way that autonomous and interconnected systems can be automated, simultaneously operated and visualized for maximum grid benefit by distribution engineers.Classic analysis based on static snapshots of loading is an inadequate practice for scheduling future investments in distribution systems and distribution management systems. This is a common practice that has been used for decades to maintain power systems over time. However, the needs of future systems require the integration of modern computing technologies and interfaces with advanced distribution system analysis. This accelerates the analysis and providing to the distribution engineer the information to make the right choice.In this paper, we discuss the needs mentioned above, and propose a flexible framework to support the development of distribution systems analysis. This multidisciplinary framework is supported by a set of open source tools developed by EPRI and other parties for presenting a modular approach to enable the next generation of distribution system analysis tools. These tools have been developed to advance the capabilities EPRI’s Open Source Distribution System Simulator OpenDSS to guide the industry on the distribution power system analysis tools and techniques.","PeriodicalId":192905,"journal":{"name":"2019 IEEE Workshop on Power Electronics and Power Quality Applications (PEPQA)","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133629967","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 magnetic system is the most-important part to its operation because energy conversion process will always be defined and bounded by the electromagnetic characteristics of its ferromagnetic core. This paper proposes an experimental method based on electromagnetic principles to obtain an approximated magnetization curve of an electric transformer, which can be used as a reference to analyze magnetic-system-behavior evolution through time. Moreover, the obtained magnetization curve considers voltage and current harmonic components produced during the test. Therefore, a detailed division of input transformer power is done, assuming the total active power are magnetic losses and the total non-active power corresponds to magnetization power. Obtained results showed the proposed method relevance, after comparing it with a magnetization curve which rejects harmonic content of signals and a magnetization curve released by a ferromagnetic material manufacturer.","PeriodicalId":192905,"journal":{"name":"2019 IEEE Workshop on Power Electronics and Power Quality Applications (PEPQA)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131627858","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 paper presents the study case of the LV electrical network of a university building (Colombia), which has a 9.1 kW PV system. Specifically, the electrical variables monitored were voltages (V), frequency (f), active power (W), voltage distortion (THDv), and harmonics at the Point of Common Coupling (PCC), to determine impairments according to Std. IEEE 1547-2018. PV systems could change the RMS value of voltage at the PCC, therefore, this variable was analysed. Likewise, the frequency was analysed to corroborate the no affectation of the interconnection of the PV system to the electrical network; it is due to the absence of rotational inertia. The solar irradiation information was measured by a pyranometer and the electrical variables by an smart meter, recording the information every 10 minutes for 32 days. The above is an initial step for a comprehensive evaluation of electrical variables with PV generation and future integration of parameters for the resilience evaluation of the electric network.","PeriodicalId":192905,"journal":{"name":"2019 IEEE Workshop on Power Electronics and Power Quality Applications (PEPQA)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125239090","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}

For this reason, several studies approach the modeling of these lighting loads to analyze their impact on the harmonic distortion in low-voltage networks. Currently, the massive penetration of LED lighting in replacement of fluorescent technology is evident; however, fluorescent lighting remains as a representative load in the energy consumption of buildings. Therefore, this paper presents the modeling of both types of lighting loads from two Norton equivalent models, the coupled matrix model and the decoupled matrix model, used to estimate the distortion of the current signal, the power consumption of the luminaires, and an escalation analysis of the models. In addition, 10 specific voltage signals were used to validate these models, thus presenting active power errors, NRMSE estimation percentages, and an escalation analysis of the models from the THDi indices.","PeriodicalId":192905,"journal":{"name":"2019 IEEE Workshop on Power Electronics and Power Quality Applications (PEPQA)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124317438","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}
