The newly developed motorcycle system is highly efficient, user friendly, and offers a solution to global environmental problems. Described is a newly developed EDLC scooter system with Dynamic Wireless Power Transfer (DWPT) as a next generation mobility concept for further diffusion of electric scooters. One of the important problems of the DWPT system is the charge and discharge cycle life of the storage device on the electric scooter. The Li-ion battery, which is widely used in EVs etc., has a limit of about 4,000 cycles. EDLCs, whose life performance is superior by far to conventional batteries, are applied for the new DWPT scooter as a power supply unit. A prototype using DD coils and a current controlled SEPP inverter has been designed. Experimental results are discussed from a practical point of view.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123347684","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}

However, this new generation model does not have natural inertia and damping properties, which is a classic feature of synchronous machines. The lack of system inertia in such power system has mainly two implications on system frequency stability, namely: higher frequency deviations (nadirs/zeniths); and larger ROCOF, which results in possible tripping of grid components. Many researchers have shown how to use inverters and energy storages with synthetic inertia control algorithms; by then, it will be recognized as synchronous generators by power grids, maintain and improve frequency stability. This paper aims to show the process of identifying the optimal placement of energy storage with SIC in order to improve frequency stability in a high RESs penetration power system using Mean-Variance Mapping Optimization (MVMO) algorithm.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123372538","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}

If not properly controlled, it will adversely affect the surrounding radio reception. Relying on ±1100 kV Zhundong-Wannan UHVDC project, the wideband model of the converter valve, the transformer, the filter and other equipment is established. And then, the research and calculation of RI levels of the converter station is carried out. The applicability of the radio interference limit of ±500 kV project for ±1100 kV converter station is also checked. The results show that when RI filter is properly installed, the total RI levels of the converter station, the RI levels of the AC line, DC line and neutral line are below the limit. Therefore, the radio interference limit of the ±500 kV converter station can be used as the radio interference limit for ±1100 kV converter station.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123184731","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 proposed method consists of hybrid clustering method and ensemble learning method. Hybrid clustering method combines the advantages of equal-length and unequal-length segmentation. Sample segments with the same trend can be clustered regardless of whether they are equal in length. The selection of segmentation points can be optimized by Bayesian algorithm, which can accelerate the K-Means clustering speed and efficiency. Ensemble learning can combine multiple weak learners into a strong learner. Finally, the data from a wind farm in southern China show that the wind power forecasting method based on the above method is more effective than the single learning model method.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121890887","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 mainly studies the impacts from the herding behaviors of electricity retailers on the monthly electricity market. We model the herding behavior model mathematically based on the relationship network of electricity retailers. Then the herding behavior model is imbedded into an electricity market model with agent-based bidding model based on reinforcement learning. We carry on a systematic simulation on MATLAB, and the simulation results illustrate that the herding behaviors might bring positive or negative effects to electricity retailers depending on different bidding strategies.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122104828","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}

With some current object detection algorithms as the core, a power grid image recognition system can be built to detect abnormal operation or foreign invasion in the power grid, which could save manpower and material resources and improve the security of the power grid. Deep learning requires a number of effective samples to work. There are few real images of hidden dangers, which cannot meet the demand. This paper aims to explore a feasible data expansion scheme.

Since higher disturbance rejection capability of GSC benefits the resolving of such stability problem, finite set model predictive control (FS-MPC) is applied. However, in weak grid, conventional FS-MPC shows poor performance as the total harmonic distortion (THD) of GSC output current is too high. To solve the problem, Kalman filter (KF) is used. The filtered signals are fed into the predictive controller instead of the directly measured current and voltage, which significantly reduce the harmonic distortion of GSC output current in the middle frequency range around 300~600Hz. Besides, in order to reduce the THD of output current, a three-level neutral point clamped (3L-NPC) grid side converter (GSC) is used. A simple sequential finite set prediction is applied to reduce the computational burden. The performance of proposed strategy is verified by simulation. Moreover, the impedance characteristic of the proposed MPC controller is presented, which is obtained by the perturbation test. From impedance viewpoint, the stability performance of proposed method in weak grid is analyzed, which is found promising.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130016275","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}
