HAPF is a sophisticated type of harmonic filter that incorporates the advantages of both active and passive filters. Better quality concerns, reduced complexity, superior efficiency, and lower costs are significant criteria that must be met in terms of quality of electricity. There is a passive filter and an active control filter in the framework adopted. The passive power filter (PPF) with a high-power rating is utilized to filter the low order harmonic current. An active power filter (APF) is utilized to filter other high order harmonics with a low power rating. The cost of the HAPF is also considerably lower than that of the APF. TSO achieves better results than the other recent algorithms. The study takes into consideration the widely used HAPF topography for model validation. In a system containing non-linear loads and non-linear source, a clear specific function representative of both total voltage harmonic distortion (VTHD) and total current harmonic distortion (ITHD) is established which helps to decrease the harmonic pollution (HP). The findings of the TSO algorithm are compatible with the associated previous analysis and with other excellent optimization techniques.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117002803","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 article investigates the technical feasibility of a hydrogen-powered fleet, in the context of a microgrid with renewable generation. The hydrogen demand is satisfied through the electrolyser powered by local RES and periodical external refueling of a local hydrogen storage system. The model of the microgrid is implemented in the open-source GNU Octave environment and is exploited to size the local storage capacity. Different types of vehicles were considered and hydrogen pressure levels were distinguished among the system components. The model was applied to the waste collection fleet and the headquarters of ASM S.p.A., a utility located in the center of Italy, chosen as a case study. The dataset of 143 vehicles was used to model the hydrogen-powered fleet. Three scenarios were evaluated: hydrogen production using i) Reverse Power Flow, ii) PV production and iii) electricity drown from the grid. The storage capacity depends on the scenarios and in the case study it ranges from about 35 to 47 m3, in comparison with 13.6 m3 of current diesel refueling system, assuming the same frequency of external refueling.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126257354","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}

To maximize the generated power from renewable energy sources while reduce the cost and improving the reliability, the concept of the Microgrid has been adopted.

As a first step a planning stage of Microgrids is, maximize the benefits of distribution generation installation where the central power plant is not practical or in case of remote areas. The main objectives of optimal sizing and siting of distribution generation are loss minimization; maximize the reliability and power quality and improvement the voltage profile and system efficiency. This paper gives a brief review on the fundamental of distributed generation technologies and the classical and modern siting and sizing approach techniques. In this context, the comprehensive reviews is carried out with a comparative between the applied methods, goals, advantages and disadvantage.

Such components are usually heavy, noisy and causes greenhouse effect. The bulky power transformers for both STATCOM and the wind farm generator hinders this configuration from applications where volume and weight are issues. As such, STATCOM-interfaced wind farm cannot be sited where size, weight, compactness, cable solution, multiport capability and environmental friendliness are critical. This paper demonstrate how solid state transformer (SST) replaces the STATCOM, the bulky transformers, and the additional reactive power compensation devices in grid integration of wind farms thereby providing smaller footprint, compactness and high performance. It is concluded that, SST-interfaced wind farms can be sited anywhere because of the reduced size, weight, compactness, cable solution, multiport capability and environmental friendliness.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130768264","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}
