Theoretic analysis shows for an internal fault, the signs of the average values of the fault component current detected by relays on both ends of the line are identical, while they are opposite for an external fault. Through comparing the signs of the average values detected by two relays on both ends of the line, an internal fault can be distinguished from an external fault. Using PSCAD software, a 1000 kV transmission line model was constructed, and extensive simulations were performed. The simulation results indicate the validity and feasibility of the proposed protection method.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"213 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":"131478703","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 proposed a novel separating pole connection (SPC) mode to address this issue. Firstly, the paper introduced the configuration concept of SPC and presented the definition of short circuit ratio for separating pole connection mode (SPCSCR). And the abilities of power transmission related with SPCSCRs under different connection modes were analyzed. Secondly, the overall control strategies for UHVDC SPC mode were studied and suggested independent control systems for two poles respectively. Finally, the dynamic behavior of SPC mode was studied by a case of UHVDC transmission using PSCAD/EMTDC, and the results validated the advantages of this structure, which has great superiority in stable operation and flexible power transmission.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"32 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":"131547394","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 DTR technology being introduced, the thermal rating of transmission line is no longer constant but time-dependent. To fully utilize the transfer capability of transmission lines, it is necessary to provide operators with probabilistic forecasting information of DTR to make dispatch decision. In this paper, a new probabilistic forecast method based on the quantile regression analysis theory is proposed to realize the probabilistic prediction of DTR. The weather parameters which have significant influence on the real-time ampacity and historical line ratings are embedded in the quantile regression prediction model. The proposed method can not only give the point prediction and interval prediction result, but also can provide the forecasting results of probability distribution function. Finally, the validity of the proposed method is illustrated by case studies.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"44 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":"131632686","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 strategy improves active channels of the outer loop, which enhances flexibility and selectivity of control by setting droop control mode cover fixed DC voltage control mode and constant active power control mode. Only by changing the control mode selection coefficients can realize switching of three kinds of control mode and self-switching of droop control mode, which reduces the fluctuation and shock generated by using the switching hardware and improves the transient stability of the system.

However, the input data of power system is actually uncertain in practice, which makes reactive power optimization an uncertain nonlinear programming, and it is not solved properly at present. To address this problem, the input data is considered as interval and reactive power optimization incorporating interval uncertainties is proposed to model this problem. In order to solve this model, genetic algorithm is employed as the solution algorithm, where reliable power flow calculation is used to judge the constraints of the model.

However, the microgrid load point outage time and outage frequency are affected directly by island load control strategy (load shedding and restoration strategy) which is not wholly considered in existing reliability evaluation methods. This paper proposes two improved strategies based on usual load control strategy considering fluctuation and correlation characteristics of renewable distributed generations power output and load demand. Applying sequential Monte Carlo simulation (SMCS) method,this paper analyzes the impacts of load control strategy on microgrid reliability quantitatively. Simulation results show that island load control strategy has important effect on microgrid reliability ,and the proposed strategies are more reasonable which can further improve microgrid reliability.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"215 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":"133963549","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 paper studies the dynamic mathematical model and the control scheme based on the proposed topology. Compared to conventional MMC, the number of IGBTs in TSC-MMC is reduced when withstanding the same dc voltage, which effectively decreases the system cost. Due to the series connection, no circulating currents exist in TSC-MMC. When the auxiliary arms on the dc side consist of full-bridge sub-modules (FBSMs), fault currents can be eliminated by blocking the cascaded FBSMs when dc fault occurs, without using circuit breakers. Moreover, an optimization of reactive power distribution between the main arms and the auxiliary arms is presented to improve the system performance. The simulation results obtained in MATLAB/Simulink are provided to verify the new topology as well as the proposed control strategies.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"320 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":"132292621","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}

A model and method of power grid differentiated planning are proposed for the consideration of special loads power supply under disaster. By introducing the probability of the electric power equipment damage in disaster, the power grid differentiated planning model on the basis of supplying power for the special loads is proposed which optimizes the outage losses and the added generation cost. Two different types of power supply for special loads are taken into account. The one ensures the full capacity of each special node, and the other ensures part capacity of the each special node because only part capacity of the node is urgent. The simulated results of IEEE 14-bus and IEEE 118-bus system demonstrate the rationality of the proposed model, which offers reference to the anti-disaster planning in power systems.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"24 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":"115342634","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 prime mover is modelled as a first-order lag transfer function with a proportional differential (PD) controller. The lag transfer function, where the value of time constant represents response speed, is used to describe dynamics of the prime mover. PD controller is used to regulate the DC bus voltage. The voltage source inverter (VSI) regulates the voltage magnitude and frequency with a proportional integral (PI) controller.
