Therefore, most countries initiate their plans to develop renewable energy on remote offshore islands. However, the integration of a significant amount of renewable power in isolated systems requires careful consideration in order to ensure high reliability and security for the power system operation. To consider system economics and stability simultaneously, an optimal algorithm to determine the real-time economic dispatch (ED) is the first step. In several island power systems, the incremental fuel cost is non monotonicity so that several conventional economic dispatch methods could not be applied to those systems. This study discussed various ED methods and implemented mixed integer linear programming (MILP) to an actual island power system.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"67 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":"125936171","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, the traditional distribution network reconfiguration method usually doesn't consider the loop closing constraints. This paper builds a new distribution network reconfiguration model considering the loop closing operation. This model takes the minimum of network losses as objective function and considers the constraints of node voltage and line power during loop closing operations. The greedy randomized adaptive search procedure algorithm is adopted to solve the new model to get the optimum reconfiguration scheme without power interruption. The numerical results in 14-bus system validate the correctness and effectiveness of the proposed new model and algorithm.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 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":"124626956","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 makes use of the method of shifted frequency analysis (SFA) in which the carrier with a frequency of 50 or 60 Hz is removed at VSC ac-side system. Using the SFA, an average-value model (AVM)-based MMC-VSC multi-scale transient model is developed, resulting in a flexible simulation of electromechanical and electromagnetic transients (EMT) by adjusting the time-step sizes. This can also be achieved in the multi-terminal DC (MTDC) transmission systems. The effectiveness of the proposed model is validated by comparisons with EMT model to simulate diverse transients such as phase-to-ground faults and wind power fluctuations in a realistic three-terminal DC grid.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"9 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":"124667628","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}

Storage could mitigate the WG volatility, so reserve provision by combination of WG and storage could be more competitive in reserve market. This paper presents a new unit commitment (UC) model, in which both WG reserve opportunity cost and storage cost are introduced into the objective, and new WG and storage reserve decision variables are also employed. Four strategies to determine WG reserve capacity and four combination modes of reserve providers are discussed. The contributions of each strategy to reduce the wind uncertainty are estimated using a statistic method based on Latin Hypercube Sampling (LHS). The simulation results show that the strategies proposed could reduce the reserve capacity allocation of conventional units and suppress the WG fluctuation, while enhancing the overall economic performance.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"29 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":"125077112","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 procedure for generating high-level synthetic information from databases containing large amounts of low-level data must therefore account for possible sensor failures and imperfect input data. Data-mining methods are widely used for recognizing the relationship between wind farm power output and wind speed, which is important for wind power prediction. Incorrect and unnatural data has great influence on the results. To address this problem, the paper presents an empirical methodology that can efficiently preprocess and filter the raw wind data using a two-stage ensemble of diverse models. First, abnormal features are extracted from raw wind data and the dataset is labeled according to the wind farm operation state records and the characters of typical abnormal data. Next, a two-stage classification model is built by Random Forest (RF) and Gradient Boosting Decision Tree (GBDT). In the first stage, a RF classifier is trained with the labeled dataset as input. In the second stage, a GBDT classifier is trained with the labeled dataset and the RF classification result as input. Finally, the testing set is predicted respectively by the two trained models and the average of forecast values of the RF model and the GBDT model are considered as the final result. The methodology was tested successfully on the data collected from a large wind farm in northeast China.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"3 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":"129901292","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}

Influence mechanism of FCLs on suppressing commutation failure is analyzed. What's more, effects of FCLs in different locations on commutation failure are compared. In addition, theoretical analysis of transient stability on multiple high voltage direct current (HVDC) commutation failure system with FCLs is discussed using the extended equal area criterion (EEAC) theory. Finally, simulation is carried out based on an actual power grid. Theoretical and simulation results show that, the action of FCLs can not only limit the short-circuit current, but also effectively suppress commutation failure and alleviate the power imbalance and the transferred system flow caused by the concurrent commutation failures, which can significantly decrease the power impact of the regional section and improve the transient stability of the system.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"9 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":"128922124","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}
