The first is a hybrid system between renewable energy photovoltaic (PV) and battery sources with Distribution STATCOM (DSTATCOM). The second is a hybrid system of (PV and battery) for a multi-input DSTATCOM. The hybrid system requires a high-coordinated design between PV, battery and output of active power for DSTATCOM or inverter. DC to DC boost circuit is used to feed Voltage Source Converter (VSC) for DSTATCOM and also to feed a hybrid inverter. DC to DC buck-boost circuit is used to charge and discharge the battery for two hybrid systems. Incremental Conductance (INC) method has been used to achieve Maximum Power Point Tracking (MPPT) in order to obtain the best duty cycle (D) for PV boost converter Isolated Gate Bipolar Transistor (IGBT). Also, the design of a Star / Delta transformer is used for the insulation of VSC DSTATCOM and to provide a circular path for zero sequence fundamental and lead to reducing the neutral current and maintain the power system balance in different load phases (unbalance load). The main purpose of using DSTATCOM is to reduce the total harmonic distortion (THD) of source currents and reduce the compensate value of current source and the neutral currents. Synchronous Reference Frame (SRF) with Unit Vector is used to control the circuit of DSTATCOM.","PeriodicalId":273236,"journal":{"name":"2020 6th International Engineering Conference “Sustainable Technology and Development\" (IEC)","volume":"42 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114123547","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}

Users may get assigned into other bands to balance the radio spectrum congestion. In this paper, radio spectrum is sensed for void detection and secondary user assignment. Cognitive users are participating the white band either by transmitting alongside with primary users or waiting until the hole is getting vacant. During the period of transmission, the behaviors of primary users are studied for determining the spectrum occupancy status. The activity of primary users is simulated as random variables due to uncertain behaviors from time perspectives. Issues like channel noise and fading effects stand as interrupters of spectrum sensing which make spectrum holes to appear busy due to such incidents. Cognitive Radio network is modeled by using MATLAB software so that both primary and secondary users can sense the spectrum and share the spectrum effectively by employing the approach of waiting time estimator which provides behaviors and activity matrix. Candidates are made to share the spectrum and hereafter transmission delay and throughput are examined when underlay and interweave spectrum sharing were in use. Three techniques are used to share the spectrum which are underlay, interweave and Feed Forward Neural Network. The results shown that feed forward neural network is outperformed in both time delay minimization and throughput enhancement.","PeriodicalId":273236,"journal":{"name":"2020 6th International Engineering Conference “Sustainable Technology and Development\" (IEC)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127007644","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}
