This paper presented a modular structure for the design and implementation of a two phase switched capacitor charge pump with arbitrary integer gain ratio using minimal number of fly-wheel capacitors. Moreover, the proposed method is able to generate the switched capacitor circuit in a simple modular fashion, which assist to facilitate automation circuit generation in modern VLSI circuit design. A design example is presented in the paper to demonstrate the design efficiency of the proposed method. The deficiency of previous design methods are reviewed. The proposed method is shown to be able to achieve the minimal number of fly-wheel capacitors and offer a simple and modular physical implementation structure that is readily applicable to automatic circuit generation system.","PeriodicalId":246799,"journal":{"name":"2021 31st Australasian Universities Power Engineering Conference (AUPEC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124396374","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 Community Battery Energy Storage Systems located in the front of the meter (FC-BESS) are attracting increased attention as potential sources of innovation for the sustainable energy transition. However, there is a lack of research that are studied the possible role of FC-BESS in power system frequency regulation where most of the works relying on the Large-scale BESS (L-BESS). Therefore, this research investigates the participation of FC-BESS in the frequency regulation considering low and high renewable penetration scenarios with different overall BESS capacities. The DigSILENT/PowerFactory software was used for implementing the simulation where the modified 14-generator simplified South-Eastern Australian Power System has been used as a test system. The obtained results revealed that FC-BESS provided a better frequency regulation when compared with the L-BESS especially in the high renewable penetration scenario.","PeriodicalId":246799,"journal":{"name":"2021 31st Australasian Universities Power Engineering Conference (AUPEC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122605942","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}

It has created a new paradigm in its application for future smart grids. The multifunction features of IEC 61850 facilitate this technology to reliably monitor, protect and control critical assets. Mostly agree, the intelligent electronic devices (IEDs) and substation automation features have the same effect as “html” had in developing web technology on IT system in 1990's. However, in order to be acceptable completely, this technology needs to gain confidence of end user, it needs to be researched further using multivendor equipment and experimented in a network comprising of complex secondary protection schemes. In this paper, a practical Blocked Busbar Protection (BBP) scheme have been implemented and tested for a single bus bar scheme, leveraging on Sampled Values (SV) and Generic Object Oriented Substation Event (GOOSE) at laboratory to prove its reliability and improvement in technology. This experiment has been carried out for three scenarios in a simulated substation network related to a process plant industry. Furthermore, this laboratory-based experiment with multivendor IEDs evaluated performance of an Ethernet and FO based process bus network to validate overall performance of BBP protection scheme. It concluded with a comparison between digital and conventional protection scheme with recommendation for future applications.","PeriodicalId":246799,"journal":{"name":"2021 31st Australasian Universities Power Engineering Conference (AUPEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122840336","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}
