The proposed inverter not only inherits the advantages of traditional qSBIs but also it has the unique features: use of less number of high power passive reactive elements in the intermediate network as well as isolated DC power supply which increases the system size. On the other hand, it is able to provide both buck and boost voltages and produces a required three-phase three-level AC output voltage in a single-stage conversion. The proposed topology has continuous input current and controlled diode bridge clamped three-level inverter to avoid the reverse recovery problem. Circuit analysis and simulation results of the proposed three-level CDBC-qSBI are presented.

Therefore, maintaining the frequency within the allowable value is essential. In the case of an emergency control such as a large generator trip, an effective load shedding plan is required to avoid frequency dropping and blackout. This paper introduces a new method for determining the location of the load shedding by using the phase angle sensitivity of two buses. Load shedding is based on the calculation sensitivity from the loads to the generator outage location. The shorter the loads have sensitivity; the larger capacity loads will shed. Experiment results showed the amount of load shedding is lower, the recovery time of frequency and rotor angle are faster than the conventional load shedding.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"22 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125855727","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 paper focuses on exploring effects of design parameters on dynamic performance of IWP. A prototype of IWP is implemented. The understanding of IWP is validated through simulation results as well as experimental results.
