Spectrograms are used to analyze the characteristics of electromechanical oscillations and to support the interpretation of the modal identification methods. The results indicate that these methods are effective in presenting the oscillatory characteristics of the system. In addition, the results show that the spectrograms help in interpretation of the modal estimates.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127051961","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}

Moreover it is important for them to analyze real time non-laboratory events. To provide this experience to the students this paper presents a remote m-learning experimental system where several types of poor power quality events can be tested.

Furthermore, the production of electricity from renewable sources is growing more and more. For these reasons Terna S.p.A. (Italian TSO) has to take advantage of existing overhead transmission lines. In order to increase the transmission capacity and the exportation of RES (Renewable Energy Sources) from Sicily to the mainland, the existing high-voltage power grid in Sicily has been studied and analysed by Neplan®, which is a powerful software tool able to analyze, plan, optimize and simulate electrical power grids. This paper, after a description of existing power grid in Sicily and HTLS (High Temperature Low Sag) Conductors, shows how it is possible to increase the active power exportation from RES to the mainland, under certain load conditions during the summer and winter.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122963831","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 power generation availability of wind turbines, solar photovoltaic panels and small hydropower are considered in the reconfiguration process. The real-time reconfiguration methodology is based on a heuristic method to determine the best settings. The method assumes that only remote controlled switches are considered in the analysis. The multicriteria analysis AHP (Analytic Hierarchy Process) method is employed to determine the best sequence of switching. The developed algorithms are integrated into a supervisory system, which allows real-time measurements and commands to the equipment. The methodology is tested in a real network of a power utility with different typical daily demand curves and distributed generation scenarios.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116592260","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}

Thus, comprehensive reliability models for wind turbines and related features are required. Composite and precise wind farms (WFs) reliability analysis includes wind turbine generator (WTG) detailed models besides wind speed (WS) probabilistic variations considering wake effects. This paper is considered as an extension to the proposed multi-state duration sampling model to asses WTG reliability integrated with a comprehensive representation for WF [1]. The paper investigates the impacts of two WTG frequency support operation algorithms on capacity factors and first hierarchical level indices. LOEE is evaluated using a novel method to emphasis the chronological coordination between load and WS attitudes. System and load points' reliability indices are estimated at moderate penetration levels of wind energy using a simplified technique. Results insure the feasibility of the composite WTG reliability model and provide reasonable indicators for WFs integration influence.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132837395","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}

In the recent years Finite Control Set Model Predictive Control (FCS-MPC) has been successfully proposed as an alternative to the traditional control techniques, due to its fast dynamic response, easy inclusion of nonlinearities and constraints in the control algorithm and the ability of incorporate several control requirements in one cost function. However, FCS-MPC is characterized by a variable switching frequency which can cause a degradation in system performance, or demand higher output filtering. In this paper a Modulated Model Predictive Control (M2PC) strategy is proposed for constant switching frequency operation and verified with a neutral-point-clamped (NPC) converter for load current regulation and DC-link capacitor voltages balancing. The aim of this control technique is to obtain a modulated waveform at the output of the converter, whilst maintaining all the desired characteristics of FCS-MPC. The feasibility of this strategy is evaluated using simulation and compared to the classical FCS-MPC strategy.","PeriodicalId":334135,"journal":{"name":"2015 IEEE 5th International Conference on Power Engineering, Energy and Electrical Drives (POWERENG)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120953411","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}

Italy and Sicily, placed in the centre of the Mediterranean Sea, play a fundamental role as a bridge between Central Europe, North Africa area and Mediterranean islands (electricity hub). This paper aims to show how power system exchanges tend to follow the direction from South to North, and how the impact of North-African power - mainly generated by RES - on the Italian system is relevant.
