Sizing is an indispensable step in the optimization of renewable energy systems because of their intermittent nature. In this context, the research work presented focuses on the development of a methodology for analysis and technical-economic evaluation carried out for a hybrid (PV/wind) system where the results are compared and discussed. Two models describe this methodology; the reliability model developed using the Loss of Power Supply Probability Concept and the Life Cycle Cost Model. As the proposed optimization problem is strongly nonlinear, to solve it we opt for the use of metaheuristic methods. In order to achieve our goal, we proposed four optimization algorithms namely: BAT Algorithm, Cuckoo Search Algorithm, FireFIy Algorithm, and Flower Pollination Algorithm. A case study is conducted to analyze a hybrid water pumping system to supply in water a habitation, located in the site of Ghardaia, south of Algeria. The results of the simulation relating to the different configurations of the system and their corresponding costs are promptly presented.","PeriodicalId":110091,"journal":{"name":"2018 International Conference on Wind Energy and Applications in Algeria (ICWEAA)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120814925","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 maintenance cost of these machines represents a big part of the total price of the kWh (40% for offshore wind energy). New maintenance practice such as e-maintenance or proactive maintenance need accurate degradation model to avoid costly corrective maintenance. The assessment of the reliability of wind turbines has become increasingly important in recent years. Majority of existing works in the literature deal with the reliability at a component level. However, the maintenance task aims to repair all the system, which cannot be guaranteed by the knowledge of the state of a single component without the consideration if its interactions with the rest of the system. In this paper, we propose a new classification of the component of a wind turbine that consists in grouping the various components by their causes of failure. The purpose of this classification is to improve the future design of the system and to allow the performance of proactive maintenance by eliminating the cause of failure and prevent their re-occurrence.","PeriodicalId":110091,"journal":{"name":"2018 International Conference on Wind Energy and Applications in Algeria (ICWEAA)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124576692","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 investigated methods are least square method (LSM), the maximum likelihood method (MLM), the empirical method (EM), the moment method (MOM), the modified maximum likelihood method (MMLM), the energy pattern factor method (EPFM) and empirical method of Iysen (EML). The results obtained from these methods have been compared with the provided data to find their accuracy and precision based on three statistical tests namely: the root mean square errors (RMSE), the correlation coefficient (R2) and the Chi-square test (χ2). Wind speed data used in the present study have been measured at six (06) Algerian weather stations. These data were recorded at 10 m above the ground during the period from 1981 to 2004. Results in this paper indicate that modified maximum likelihood method present the best fit to Weibull distribution and moment method provides the lowest degree of fit for all the stations. This study gives also a detailed analysis of wind characteristics in the study area. It appears from the results that Tindouf station is the windiest site especially in winter months.","PeriodicalId":110091,"journal":{"name":"2018 International Conference on Wind Energy and Applications in Algeria (ICWEAA)","volume":"88 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127439549","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}
