In general, the disturbance records are stored at the utility central office or control center, leading to a substantial amount of data that in practice is not analysed in its totality. This paper describes a methodology to deal with this problem by proposing a fuzzy classification system. From the DFR phasor records, currents and voltages sampled signal are extracted. The data is processed in order to calculate some meaningful features that are applied to a fuzzy inference system. The fuzzyfied input variables are processed by fuzzy rules which emulate the engineers reasoning at the control center. The output of the fuzzy system indicate which kind of disturbance occurred and what is its degree of pertinence. The proposed methodology enables an automated pre-classification of the DFR data helping the engineers by focusing their attention to the most relevant occurrences. Related studies show that approximately 95% of the disturbance records can be automatically archived because they result from normal operational procedures. The results obtained by using real disturbance records show that the proposed scheme is able to correctly classify the occurrences and also to generalize the result from situations not directly represented in the rule set.","PeriodicalId":155801,"journal":{"name":"2014 Power Systems Computation Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121228224","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 lower (third) level models the market outcome; the intermediate (second) level models the equilibrium in generation capacity expansion by taking into account the outcomes of the market equilibrium at the third level. The upper (first) level models the expansion of the transmission network. The second and third levels are modeled as an Equilibrium Problem with Equilibrium Constraints (EPEC) parameterized in terms of the optimal decisions of the transmission planner. This three-level hierarchy is motivated by the fact that transmission planners should consider expansions in generation that may take place, as well as the clearing of the market related to generation expansion, in order to make their decisions. At the first level, the transmission planner can take different positions with different impacts in the system because a manifold of equilibria is possible with different costs for the system. Unlike previously reported hierarchical approaches, which are implicitly formulated as optimistic, we solve the pessimistic solution of the problem (the transmission planner takes a pessimistic attitude towards the outcome of the generation expansion equilibrium). Results for a test power system are presented in order to show the efficiency and interpretations of the proposed model.","PeriodicalId":155801,"journal":{"name":"2014 Power Systems Computation Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123820734","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, these programs are designed for conventional power supply systems which consist of predominantly consumers. Through the development of electrical power systems in Europe and particularly the establishment of many new offshore wind farms, these lead to an enormous change in the power supply grids (infeed grids). Therefore it is a substantial need for adaptation of these programs to determine the reliability of the overall power system in a realistic way. In this paper, additionally to the offshore specific reliability indices, three new models are presented. These models are especially created for offshore wind farms and their characteristics. These models are respectively: the weather influence model, the power infeed control model and the reliability modeling of the wind turbine generator (WTG). Based on one exemplary wind farm design, the developed models are compared with the conventional models. This work presents the impact of the different improved models on the reliability results. The importance and the necessity of these established models in order to reach more realistic and environmental depended reliability analysis results are hereby illustrated.","PeriodicalId":155801,"journal":{"name":"2014 Power Systems Computation Conference","volume":"319 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133400906","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}
