The main objective of this work is to implement a low-cost, secure, interoperable and scalable system to monitor photovoltaic installations and battery energy storage systems, integrated into distribution networks, in real time and to control them remotely for an optimal management of energy. An architecture, based on IoT technology and the Message Queuing Telemetry Transport protocol (MQTT), has been proposed and tested on a simple photovoltaic system in order to transmit the monitored data over the Internet and display them on a graphical interface. These collected data will also be used to feed the optimization and energy management algorithm, which aims to choose the optimal combination of production units having a low energy cost. Orders can therefore be sent from the interface to these units in order to execute the optimal decision of the algorithm.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"32 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115800409","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 experimental setup consists of a parabolic trough collector connected with a helical coil heat exchanger (HTX) that surrounds the external wall of a cylindrical batch reactor. This last component was partially filled with a mixture of demineralized water and dried raw olive pomace in appropriate portion. The mixture was heated by the thermal oil (Heat Transfer Fluid: HTF) circulating inside the HTX. Three K-type thermocouples were used for measuring temperature values at the entrance and at the exit of the serpentine as well as inside the batch reactor. Also, a flowmeter and a manometer measured the HTF flow rate and autogenous pressure inside the reactor respectively. Three temperature profiles are presented namely, temperature inside the batch reactor, HTF temperature at the heat exchanger entrance and at the serpentine exit. Also, different thermal powers, thermal efficiency and convective and overall heat transfer coefficients are examined.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"501 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116032205","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}

This paper presents a viable solution to the improper management of UCOs in the city of Ifrane, Morocco (14000 inhabitants). The solution consists of the collection of the city’s UCOs and their transformation into useful biodiesel. The project has been developed over the past four years and included multiple levels of intervention: research, engineering, social engagement, logistics and economics. In this paper, we focus solely on the technical and engineering design aspects of the project. An average of 300 liters of UCOs was collected each week from the various collection points in the city. A pilot unit with a production capacity of 250 liters of biodiesel per batch was developed: schematics, automation, and process flow are discussed. The pilot unit presented several opportunities for innovation beyond what is found in most literature on the subject. Solar energy and biomass are used to fulfill the heat requirement of the chemical reactions. The recycling of methanol and glycerol are performed. The entire transformation process is automated using open-source Arduino microcontrollers and switch relays. The biodiesel yield is estimated to be between 85% and 93% of the transformed UCO in about two hours of reaction. This work can be used by individuals, NGOs, actors in academic institutions, and local authorities as inspiration when tackling the issue of improper disposal of UCOs in their area from a technical design point of view.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129699626","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 technology has shown growing interest due to its numerous advantages and its potential for energy-saving. FO process is, however, still facing important limitations related to efficient membrane and draw agent to achieve higher performances. Water diffusion in FO is driven by the osmotic pressure gradient from a highly concentrated stream (draw solution) to a lower concentration solution (the feed stream) across a semi-permeable membrane. Concentration polarization (CP) phenomena have been reported to be the most important factor causing water flux decline in FO process. Reverse solute flux (RSF) is also considered as a major issue in FO. In this work, an experimental study has been carried out for the evaluation of CP phenomena and RSF in FO process. Ammonium bicarbonate and sodium chloride have been used respectively as draw and feed solutions. Results have shown that dilutive internal concentration polarization phenomena (ICP) induced a draw solution osmotic pressure reduction of 42%. Concentrative external concentration polarization (ECP) effects have shown to affect driving force to a lesser extent, the combined effect of ICP and ECP caused a water decline of 51.5%. A concentration profile based on the obtained results across the FO membrane has been defined.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125024086","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}
