The two major classification of the DGs namely synchronous based DGs (SDG) and inverter based DGs (IDG) exhibit different impacts on the grid which may limit their penetration level. Hence, this paper proposes a two-phase approach for maximizing the penetration of DGs complying with the collective grid constraints such as voltage harmonics and relay coordination limits exhibited by IDGs and SDGs respectively. The proposed method is tested on a standard IEEE 14-bus system with different DG penetration levels. Various case studies are conducted on the test system to demonstrate the efficacy of the proposed approach. The results obtained show the choice of the suitable optimization algorithm and the impacts of the constraints considered for optimal sizing and placement of the DGs.","PeriodicalId":208739,"journal":{"name":"2015 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","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":"114877256","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 modern day generators are built with higher rating and better cooling techniques, resulting in larger machine impedances. The closely knit transmission network has resulted in decreased system impedance. These changes have increased the chances of occurrence of out of step condition with swings passing through the generator impedance circle. This paper describes an adaptive out of step protection scheme for detecting this condition. The new scheme proposed uses both impedance and power measurement to obtain a comprehensive protection scheme which uses locally available information and does not require extensive simulation studies for setting the relay. Adaptive swing classifier logic is introduced to differentiate between stable and unstable swings. The performance of the proposed scheme is compared with the conventional single blinder scheme by testing it on a multi-machine system.","PeriodicalId":208739,"journal":{"name":"2015 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"18 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":"132165391","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 medium voltage (MV) cable is an important asset of a distribution network and it must guarantee a stable operation of the supply. With the increasing age of the underground MV cables in power grids, the accident and failure arising from insulation degradation is becoming one of the main challenges against power system reliability. It is also essential economically to extend the life span of the medium voltage cable. Continuous on-line partial discharge (PD) monitoring is an excellent way to determine the overall health of the MV components and to detect incipient faults in underground cables. However, continuous on-line PD monitoring is not widely used primarily because no adequate cost-effective solution is available for permanent installation. This paper presents the development of a versatile solution for continuous on-line PD monitoring of MV cables at secondary substation. The laboratory tests and data analysis exhibit the capability of the proposed system to detect PD signals successfully.","PeriodicalId":208739,"journal":{"name":"2015 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"83 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":"132233637","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}

Solar photovoltaic (PV) systems are experiencing a world-wide rapid take-up due to their rapidly reducing cost and climate-friendly attributes. This study aims to develop a PV-Diesel hybrid power system for the remote township of Cue (27.4210S, 117.8960E), to investigate the techno-economic possibilities of integrating solar PV within the existing diesel network. Hybrid Optimization Model for Electric Renewable (HOMER) has been used to evaluate the performance of the hybrid power system based on the performance metrics: net present cost (NPC), cost of energy (COE), renewable fraction (RF) and greenhouse gas (GHG) emissions. Simulation, optimization and sensitivity analysis of the models has been performed and an optimum model selection has been made, based on techno-economic and environmental performance. From the simulation analysis, it is clearly observed that Cue, as well as other mid-west locations within Western Australia, has enormous potential for substantially increasing the use of solar PV in parallel with the existing stand-alone generators, thereby reducing the use of diesel fuel, generator operating hours, resulting in reduced energy costs and GHG emissions.","PeriodicalId":208739,"journal":{"name":"2015 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"123 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":"128415374","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}

Although EV increases the load pressure to the grid, it can also serve as the potential storage to facilitate the demand response for residential customers. In this paper, we propose an optimal and automatic scheduling scheme to exploit the benefits of EV not only from residential side but also from utility companies. Specifically we consider that the EVs can achieve a two-way discharging, either supply the power usage of its house (i.e., V2H) when the electric price is high or sell back to the Grid (i.e., V2G) if the market price is more attractive. The objective is to minimize the total cost, including electricity expenditure and storage depreciation cost, while satisfying various practical constraints. Simulation results show our proposed scheme can not only lower the cost but also share part of the pressure from utility companies.","PeriodicalId":208739,"journal":{"name":"2015 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","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":"134464300","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 requires sophisticated real-time embedded control systems to manage distributed energy resources. These network-connected systems will be exposed to wide range of security threats when incorporating information and communication technologies. Securing embedded systems has unique resource and timing constraints. We developed a real-time application-specific malware detection system that runs on a dedicated hardware implemented in FPGA. It runs in parallel with the embedded system being monitored and provides real-time feedback to the running application in case of security violation. The system adopts the anomaly-based malware detection techniques. We model the correct program behaviors as function call graph. The information is extracted from application source code offline before runtime. The system is able to detect any attack that causes the embedded application to deviate from the pre-defined permissible behavior with minimal hardware overheads.","PeriodicalId":208739,"journal":{"name":"2015 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","volume":"80 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":"133692875","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}

Although the H-infinity controller has a highly robust control performance, it has not been put into practical use because of the intricate of its theory and structure. Thus, to obtain high robustness, we deal with the H-infinity problem under the condition that the PSS structure is fixed as a lead-lag compensator. To this end, we add an additional reactive power input to the PSS. The parameter of the multi-input lead-lag PSS is optimized by Particle Swarm Optimization (PSO) that has an evaluation function which takes into account a closed loop H-infinity norm and a desired response. The damping of the PSS response is identified by using Prony method. The validity of the proposed PSS is demonstrated using a 3-machine 9-bus system model.","PeriodicalId":208739,"journal":{"name":"2015 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA)","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":"122108728","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}
