The influence of chemical composition of raw materials on the characteristics of obtained products has been investigated by using fixed bed reactor. The aim of this work is to identify the best use of products recovered after pyrolysis of plastic wastes collected from chemical and biochemical laboratories. This work is developed in a laboratory bench installation design to perform O2-free processing at atmospheric pressure. The process parameters such as pyrolysis temperature and adapted heating rate have been determined through the transposition of thermal and kinetic information provided by thermogravimetric analysis (TGA). Gas-chromatography techniques have been used to identify the chemical composition of gases (GC/TCD) and liquids (GC/FID-MS). It was established that polymer wastes can led to a valuable liquid products, with encouraging energetic properties that allow their blending with fuels currently used without altering the performances of burning devices.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129205665","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, due to the variation of wind speed, wind energy is a fluctuated source and remains uncertain. It has an impact in grid stability. In this context, in order to improve the output characteristics of wind farms, several operators are going to develop new solutions. In this study, we propose a solution that allows limiting the wind power fluctuated and increasing wind energy penetration into power network. Then, we focus our attention on the cooperation between a wind farms and hydro-storage station with a given pumping capacity.

The comparison between the two algorithms at low perturbation rates has been the subject of a number of publications. No much attention was paid to such a comparison at high perturbation rates, when system response to MPPT perturbations is never allowed to settle, although higher energy utilization efficiency and better system performance may be achieved in this operation mode. This paper presents a comprehensive experimental and theoretical comparison between the two algorithms when operated at high perturbation rates.

The studies of the thermal performances of the solar combisystem were achieved by comparing of two configurations: In the first configuration, the floor of the entire house is heated with a single active layer that passing through living room, washroom, bathroom, kitchen, dining room, bedroom and kids' room. In the second configuration, the floor of the house is heated with two independent coils, the first through living room, washroom, bathroom and kitchen and the second through dining room, bedroom and kids room. The results shows that the optimal architecture of the solar combisystem consists on using of two active layers integrated inside the floor heating.

The hybrid system is the combination of photovoltaic (PV) array, wind turbine via a common dc bus. For PV generation system, the Incremental Conductance (IncCond) MPPT algorithm is used to be compared with the Perturb and Observe (P&O) MPPT algorithm. For wind generation system, a simple and cost maximum power extraction control strategy is proposed for the permanent magnet synchronous generator (PMSG) based variable speed wind energy conversion system. The speed of PMSG is estimate using a model reference adaptive speed (MRAS) observers only by measuring phase voltages and currents. Extensive simulation results using Matlab/SIMULINK established that the performance of the controllers is quite satisfactory under to climatic condition step change (wind speed, irradiance). The effective ness of the developed controller is also tested for step no load to full load.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114744880","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}
