The uncertainties of load distribution and variation have introduced a great complexity to the task of maintaining system voltage within the permitted range. In this paper, small-scale generator, known as distributed generation (DG), is employed in the system and acting as a voltage regulator. The output of DG is controlled in such a way that acceptable level of electrical supply quality is achieved with a reasonable operating cost. The DG controller is tested with a non-uniformly varying load on the time domain basis. Simulations have been conducted with both short term (few hundred seconds) and long term (weekly) load data to validate the proposed control technique. Results have proved that the system is well functioning not only technically but also economically.","PeriodicalId":262597,"journal":{"name":"2006 International Conference on Power Electronic, Drives and Energy Systems","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125435436","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 topology of the IPQC itself ensures variable bi-directional DC voltage and reversible current in both buck and boost modes, however, application of the hysteresis-band current control based closed loop technique renders operation of the converter in either mode at any power factor, in any quadrant, with a harmonic profile at the utility interface conforming to the IEEE 519 stipulations by appropriately modifying the switching pattern of the 4QSWs. The control strategy is evaluated for the IPQC by simulations implemented in the single and three phase topologies of the converter. Results confirm that the technique confers IEEE 519 compliance on the converter with regard to the total harmonic distortion (THD), and, are presented for unity, leading and lagging power factor operations in both modes for the four quadrants.","PeriodicalId":262597,"journal":{"name":"2006 International Conference on Power Electronic, Drives and Energy Systems","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122751638","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 converter is operated in buck converter mode. An additional switch is used to operate the devices in such a manner, that the charging and discharging take place in a resonant fashion. A higher efficiency can be achieved by turning off the switch under zero current switching (ZCS). The converter is further modified to operate with two switches in a diode bridge converter instead of three switches. Complete theoretical analysis, simulation results and experimental data on a 500W converter are presented to demonstrate the superiority of the new control strategy with reduced device stress.
