The procedure involves sectionalizing the affected system into a number of sub-systems or islands. This paper describes a heuristic based strategy to determine number of islands based on lowest total restoration time, TRT. The strategy involves a searching method to identify cut-set (set of transmission lines that separate blackout system to islands). The main objective of the strategy is to search the optimum lines of the cut-set which create islands with almost similar parallel restoration time. Thus, the total restoration time for complete system interconnection can be significantly reduced. Physical properties and operation data of affected system are employed in the proposed method to assist the searching process using the graph theory model. Other than that, restoration constraints such as load power generation balance and availability of black start generators are considered. Load flow analysis is carried out on the selected islands to ensure that the voltage profile stability performance is in the acceptable range. IEEE 39-bus and 118-bus system are used to demonstrate the effectiveness of the method in determining number of islands. Promising results in terms bf TRT was compared to other methods reported in the literature.","PeriodicalId":126140,"journal":{"name":"2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127888107","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}

Carrier Based Space Vector Modulation which can be digitally implemented for N-levels is proposed. This modulation is similar to Space Vector Modulation with less complexity avoiding the sector identification. This modulation technique is compared to validate its simplicity, robustness and good dynamic response with existing Sine Pulse Width and SVPWM techniques. Closed loop control is carried out with Field Oriented Control (FOC) and Direct Torque Control (DTC). To support the simulation analysis, a prototype of three-level diode-clamped inverter is implemented and the output is fed to 3-phase, 4-pole, and 400 V, 50 Hz, 0.45kW, 1500 RPM, IPMSM. Control logic is designed using DSP TMS320f28335 controller. The results obtained are quite suitable for electric vehicle applications, which give smooth operation with stronger acceleration and less maintenance.","PeriodicalId":126140,"journal":{"name":"2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"312 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115745013","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}

In this paper, the effects of the Australian climate and building wall types on low voltage networks (LVN) are investigated using droop-based solar curtailment control. Residential solar curtailment requirements of a residential LVN is compared in ten Australian cities, covering all major Australian climate zones. In each city, two types of building walls are compared: timber cladding walls (low thermal inertia) and double brick walls (high thermal inertia). The LVN with high-thermal-inertia buildings has more over-voltage problems and has 1%-7% more solar curtailment requirement than the LVN with low-thermal-inertia buildings. Climates with more temperate summers require higher solar curtailment, e.g., 31% in Mildura, compared to the climates with hot summers, e.g., 24% in Darwin. This study shows that high thermal inertia buildings would benefit from energy storage technologies, such as battery storage or thermal storage, to alleviate over-voltage issues in the power distribution network.","PeriodicalId":126140,"journal":{"name":"2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131346706","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}

In addition, uncoordinated charging of EV would make situation more severe and require network reinforcement. One of the potential solutions to this problem is peak load management through EVs coordinated charging. In this regard, this paper put forward Time-of-Use (TOU) price based Vehicle-to-Grid V2G scheduling strategy of EV Aggregator (EVA) with the aim to optimize EVs coordinated charging and earn monetary benefits for all stakeholders such as EV owners and System Operator (So). For this, Price-based Demand Response Program (PBDRP) is proposed to enhance the value of EV owners. State-of-Charge (SOC), TOU-PBDR and modulation of charging/discharging rate is considered for the pragmatic formulation of V2G scheduling problem of EVA. Simulation result highlights the effectiveness of the proposed model regarding peak load management and monetary benefits for all stakeholders. Moreover, this model offers regulation services to SO for supporting grid stability and thus avoid inevitable contingencies.","PeriodicalId":126140,"journal":{"name":"2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131089956","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}

Solid state Transformer which power electronics converter which has characteristics that is not possessed by conventional transformer like availability of DC-port, current limit, can be used with different frequency at input and output, voltage sag compensation, better power quality, reduced size and weight because of high frequency transformer, current regulation etc. these all characteristics makes SST suitable for dc micro grid for new micro grid architecture. Three phase DAB is most suited for high power. Three phase converter is preferred in the intermediate stage of Solid state transformer due to its high full load efficiency, less RMS current, better transformer utilization factor, reduced filter and volume.
