The new analysis of the unbalanced three-phase system is achieved by symmetrical components method. The method is based on the properties of the Hilbert transform. At the beginning, relations are developed for calculating the symmetrical components in “abc” natural coordinates of a three-phase system. In the end, similar relationships in “$boldsymbol{alpha}boldsymbol{beta}$” coordinates are developed. There are also presented the conversion relations between different quantities expressed in both coordinate systems. The analysis is done for the general case of an unbalanced, non-sinusoidal, distorted three-phase system. Symmetrical components will be implicitly determined for each group of harmonics of the same frequency. The main conclusion is that the Hilbert transform based method represents an important analytical and computational tool regarding the unbalanced three-phase systems.","PeriodicalId":397346,"journal":{"name":"2019 8th International Conference on Modern Power Systems (MPS)","volume":"119 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":"121862031","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 renewable energies and the energy efficiency measures have an essential role in energy transition. Presently, there is a need for a holistic approach of the sustainable investments that significantly contribute to the reduction of carbon footprint, giving the answers to all stakeholders and converting the project's results in relevant information for each of the involved party. The energy performance contracting model faces difficulties in facile implementation in Romania, as in other European countries, due to the disconnection between expectations of involved parties. The energy performance investment project is contributing to CO2 reduction, involves sustainability, needs legislative framework and technological development, jobs creation, comfort increase, political support, provide replication model or allow incremental implementation if the case. The present paper intends to contribute to the development of the energy efficiency contracting model in Europe proving a new approach of the energy investment projects from the perspective of all relevant stakeholders: beneficiaries, technicians, financiers, authorities, community and environmental activists. The paper propose a methodology for evaluation the performance of energy efficiency solutions to tertiary consumers based on a multi-criteria assessment built to analyze the technical, energy efficiency, environmental, economic and social impacts associated with the analyzed energy system. The proposed methodology for evaluation the performance of the energy efficiency improvement solutions will allow the development of sustainable energy efficiency projects technically and economically feasible and environment friendly to assimilate as attractive investments with priority to implementation.","PeriodicalId":397346,"journal":{"name":"2019 8th International Conference on Modern Power Systems (MPS)","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":"127097326","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 load forecasting model quality is directly related to two factors, the definition of the input variables of the forecasting model and the mathematical modeling of this model. About the first aspect, the most significant exogenous influences on demand in the short-term load forecasting horizon are the weather variables, mainly temperature, humidity and wind speed. Regardless of the weather variable considered, it is necessary to perform a correlation study of the influence of this variable on demand, in each different region and climatic season. Thus, the objective of this work is to present a study of feature selection related to weather variables considering the application of a short-term load forecasting model to four different climate zones. This study, based on a feature selection tool that generates results of relation between the demand and the weather variables, aims to justify the definition of different weather inputs for each region, seeking to increase the quality of the load forecasting results. Also, the feature selection tool is based on different math definitions, that contributes to a better pattern recognition.","PeriodicalId":397346,"journal":{"name":"2019 8th International Conference on Modern Power Systems (MPS)","volume":"116 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":"124239940","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 analysis of the circuit is realized with two different types of software which have the same method of compilation. The presented study was used as a reference point for the integrated circuit (IC), ISL “78227”, circuit that has been used in the series production for automotive industry projects, especially as a boost converter driver. The DC-DC boost converter was designed to rise up the voltage from $mathbf{V}_{mathbf{in}}=9mathbf{V}$ up to $mathbf{V}_{mathbf{out}_1}=50mathbf{V}$ and $mathbf{V}_{mathbf{out}_2}=55mathbf{V}$. During the simulation, the main focus stayed on the circuit design within two simulation software and also on the component parametrization in according with the components that were taken in consideration within the project requirements. Nevertheless, the paper presents the results that were obtain after the simulation and also shown both variants of the output voltage in according with the project requirements.
