In previous studies, the feasibility and effectiveness of an automatic real-time control strategy of HVDC in a single HVDC link system have been discussed. This paper focuses on the application of this control strategy in a multi-HVDC links system and the mutual influence between different HVDC links. Simulations in a transient simulation model of China Southern Power Grid (CSG) by the EMTDC/PSCAD software show that the coordinated control of multi-HVDC links contributes a significant improvement of the system transient stability after a large disturbance. When all of the four HVDC lines in CSG involve in the coordinated control, the stability of the system will be most obviously improved after a large disturbance. Meanwhile the mutual influence between the HVDC links is very limited.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129561164","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}

This paper proposes two real-time coordinated charging strategies to improve the charging costs of electric bus fast charging station (EBFCS) by responding to the Time-of-Use (TOU) electricity prices. At first, a mixed integer linear programming (MILP) based optimal charging strategy is formulated by considering the constraints of PEB charging needs, continuous charging and distribution transformer capacity. To reduce the computation time, a suboptimal strategy is presented with a two-stage model. At the first stage, an ideal charging load profile is optimized without consideration of continuous charging; at the second stage, the continuous charging loads are scheduled to follow the ideal profile through heuristic method. In case studies, charging costs and load profiles under the distribution transformer are respectively simulated under optimal charging strategy, suboptimal charging strategy and uncoordinated charging scenarios. Simulation results demonstrate that the proposed two strategies reduce both the charging costs and the peak load effectively. Comparison between two strategies indicates that the suboptimal charging strategy improves computation efficiency dramatically with only a little charging cost increment.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124720593","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 alleviate the curtailment, optimizing the integrated wind and solar power capacities becomes an urgent need. This paper proposes an improved method to optimize the wind and solar power capacity based on the time sequence simulation technology. An optimization model is proposed to maximize the environmental benefit for a regional power network with considering the constraints of system power balance, thermal unit peak load regulation ability, system spinning reserve, power and heating coupling of the co-generation unit and tie-line transmission capacity. To handle the transmission capacity constraint, the regional power network is aggregated for simplicity. The annual wind and solar power time sequences are incorporated as inputs for optimization. By giving a series of scenarios with different proportion of wind and solar energy, the optimal capacities are obtained by comparing the environmental benefit and the curtailment. Case studies are conducted with a provincial power network of China and testing results verify the effectiveness of the proposed method.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126670422","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}

These uncertain factors usually will aggravate the difficulty of reliability evaluation. On the other hand, the renewable energy generator likes a single wind turbine usually has small capacity. A wind farm has a plenty of wind turbines. The enormous increase of system dimension due to the integration of a plenty of wind turbines will also causes the decrease of system reliability evaluation efficiency. Hence, a high efficient reliability evaluation algorithm aiming at the composite system with the high proportion of renewable energy should be developed. As far as we know, high computation efficiency is an eternal topic of power system reliability evaluation. Recently, a Cross Entropy-Importance Sampling (CE-IS) based reliability evaluation method has been developed successfully in the application to power system reliability evaluation. All cases verify that the method can improve the evaluation efficiency remarkably, especially in those highly reliable systems (i.e. cut-load events are rare events). This paper studies the approach to deal with the composite system reliability evaluation considering the integration of wind energy using Cross Entropy (CE) method, and proposes three different approaches to deal with the problem. Finally, a modified test system with the integration of renewable energy is proposed to compare the effects of these integration approaches.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127032728","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}

Only single-phase grounding faults caused by external factors including lightning faults, wildfires faults, guano-caused flashovers, insulator contamination flashovers, object contacts and vehicle accidents are considered in this paper. From detailed analysis of the fault mechanisms and the waveforms of fault recorders, six influential factors are selected to characterize the six types of outages as follows: weather, season, time of day, DC component and high-frequency harmonic component in the zero sequence current and fault impedance magnitude. Discrete Fourier transform (DFT) is used for the analysis the frequency components of the fault phase voltage and current waveforms. The combination of these characteristics are used for training and testing the SVM architecture. In addition, genetic algorithm is applied to the SVM classifier to determine the optimal parametric settings which is proved that it can achieve higher classification accuracy. Successful testing of the proposed methodology proves its validity for identification of different fault reason types.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"15 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120899554","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}
