These variations can cause serious damages to the grid causing sometimes black-outs. In terms of technical operations, the chaotic behavior of DNI makes the dispatch in many cases impossible to provide electricity for the right place at the right time when the need is there. This study proposes an operational method to dispatch electricity based on DNI and load forecasting using statistical and machine learning techniques combined with the dispatch tool provided in SAM (System Advisor Model) software. The case study explored is the Solar Tower with the molten salt combined with Thermal Energy Storage (TES) system used in NOOR 3 Ouarzazate, Morocco. The aim of the proposed method is to reduce the effect of fluctuations on the electrical grid by anticipating them and providing an easier and more accurate operational way of scheduling and making dispatch decisions. The results show a considerable increase in the performance of the simulated grid due to the new proposed dispatch method and the machine learning techniques used.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"380 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88685681","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 weather is hot and humid in the summer, but mild in the winter. Aridity is the general characteristic of the country, while natural vegetation such as trees and shrubs can be found in some regions. The hot climate and high humidity in summer as well as aridity in Qatar impose major challenges for expansion in the agricultural sector. The government of Qatar has been and will continue to support local food production through the Qatar National Food Security Program (QNFSP) and other initiatives to develop the agricultural sector to the maximum realizable extent. The focus of this research work is on design, modeling and optimization of small to large-scale agricultural greenhouses for improving their energy and water use efficiency and equipping them with solar PV systems. The solar PV is integrated with the structure of greenhouse, as a roof mounted system, without compromising the supply of daylight and required solar energy for plants growth. The ultimate goal is to develop a Passive Solar Greenhouse (PSGH) design that reduces the cooling load drastically and integrate it with solar cooling to cover 100% of the cooling load. The aim of the optimized PSGH design is to maintain favorable crops growing conditions inside a greenhouse such as temperature, humidity, daylight, ventilation and minimize the cooling load and energy consumption. Five different sizes of pitched roof greenhouses with the optimized PSGH design (28mx8m, 28mx20m, 28mx50m, 28m×100m and 28mx150m) were modeled and compared with the conventional greenhouse design in terms of their dynamic cooling loads and overall energy consumption. The analysis showed that the cooling load of the PSGH design has been reduced by approximately 74%, while over 77% reduction in annual energy consumption has been achieved, compared to a conventional greenhouse design.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"62 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84108774","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}

These are alarmingly high levels and there are fears that if this situation is not addressed, the world will end up “drowning” in plastic. Researches that have been done have revealed the ubiquitous nature of plastic because regions which were previously thought to be virgin (untouched) such as The Arctic have been contaminated with microplastics. Little is known about the effects of microplastics on human health. But what is clear is that they have landed on our tables, in the form of table salt or fish that we consume. Furthermore, graphic images have emerged of whales that have died from ingesting plastics as well as entanglement and suffocation of other aquatic animals. Plastic use has significantly increased over the years, mainly because it's a cheap form of material, it can easily be moulded and unlike paper, plastic keeps foods fresh for longer periods. Of late, there has been a growing trend of making less durable plastic materials which makes it difficult to reuse. These plastics are referred to as single use plastics and are said to account for 40% of all plastics manufactured. Statistics also show that from the total plastics produced globally, a meagre 9% has been recycled. The need to explore the use of plastics as an alternative energy source and for material recovery has become more urgent than ever in order to protect the environment and its inhabitants.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"29 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90526169","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}
