Embedded generation including solar rooftop PVs and other demand management means do not only change the demand profile of the system but also other electrical characteristics of the distribution network. Advanced power system analysis tools are required to address the needs for more accurate modelling. The ability to integrate with other enterprise software systems offers opportunities to achieve efficiency gains in day-to-day operations as well as investment planning. Three projects undertaken by the authors are selected to illustrate how the new challenges are resolved using advanced analysis tools. The projects include the modelling of PV and battery inverter systems on distribution system, calculation and optimization of distribution losses, and fast assessment of domestic PV connection based on GIS and asset management data.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114665507","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}

Therefore, power flow solver for the whole network is highly required. A flexible power flow solver for the interconnected transmission and distribution network is designed based on decomposition and coordination method. Two commercial software, PSASP and DIgSILENT are applied to solve power flow for transmission and distribution respectively. The coordinator is designed to be model-free and solved by Jacobian-Free Newton-GMRES(m) algorithm. The provided test results validate its good accuracy and convergence performance for unbalanced power flow solution.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116128252","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}

Firstly, the concept of FGM and its effect on electric field (E-field) optimization is introduced. Secondly, optimization of permittivity FGM (e-FGM) insulator is studied. A numerical technique for the optimization of permittivity distribution in e- FGM spacer is proposed and simulated on three typical spacer models, i.e. cone type, disk type and basin type. It is confirmed that the FGM application could significantly improve the E-field distribution. Moreover, the effect of the shrinking coefficient in the algorithm is discussed. Finally, concept of a novel fabrication method for FGM spacers is proposed based on the rapid- developing 3D printing technology. The process and advantage of this `bottom to up' method is discussed.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121788080","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 dynamic performance of the interconnector is relatively less certain due to modelling complexity and difficulty in testing, despite its importance to power system security. This paper firstly presents the calibration result of the small signal power system dynamic models of the Australian National Electricity Market (NEM), using the field test measurements of SVC Power Oscillation Dampers in Queensland. Based on the calibrated models, the sensitivities of a number of parameters to system damping are evaluated. The results show that apart from the generator PSS design, the inter-area mode damping is also significantly influenced by the modelling of loads, generator (inertia in particular) and governor.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123614053","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}

Advocating to bring attention to the impact of climate change and to reflect on the actions individuals can take to alleviate its effects, this study aimed to assess whether the event resulted in any significant reductions in energy consumption. Examined at both a state wide and residential level in New South Wales, the results of this study determined that at a state level it was extremely difficult to observe any notable impact. At a residential level however the influence of Earth Hour is much more prevalent with the event being seen to slowly gain momentum resulting in significant reductions between the years of 2008 to 2012. In recent years however its popularity has declined and the event has ceased to have any significant reduction in consumption.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127675799","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 investigate the behavior of these decision makers in local energy and reserve equilibrium, a bilevel optimization model is presented. In the proposed bi-level model, Disco and MGs are considered as the leader and the followers, respectively. Disco decides about energy and reserve price in local markets. In addition, MGs decides about optimal scheduling of their resources and energy and reserve interactions with Disco in local markets. In energy and reserve equilibrium point, the local energy and reserve prices and the amount of energy and reserve interactions between Disco and MGs are determined.

A new control system is proposed for each rectifier, inverter and DC/DC converter to enable independent operation of each terminal. DC voltage droop feedback is designed to moderate power order at each terminal which facilitates DC power balancing without communication between terminals. Simulation on detailed PSCAD model is presented for several extreme operating scenarios and responses confirm many operational benefits of the proposed topology. Loss of one terminal in this 4-terminal DC grid, for example, will not disturb operation of the remaining 3 terminals. This preliminary study concludes that there are no serious technical challenges, while operating benefits might be significant.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115489758","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}
