In building energy analysis, the heat transfer through its envelope usually neglect the transport of moisture in the porous structure of the envelope and a constant thermal conductivity, k-value, of thermal insulation material is used to assess the heat transfer through the building envelope. In reality, the building envelope is subjected to the combined thermal and moisture gradients so that an accurate heat transfer determination requires a simultaneous calculation of both sensible and latent effects. Actually, the k-value is a complex function of temperature, moisture content, and density, which requires more accurate evaluation to lead to data that are more realistic to achieve a precise building energy assessment. The findings revealed that the impact of the change of these parameters on the cooling load calculation is significant, especially at a high operating temperature and moisture content.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130424512","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}

Conventionally, coal and methane are used as feedstock for methanol synthesis but its combustion generates CO2 emission, one of the main sources of global warming. The purpose of this study is to analyze through an analytical model the methanol production from algae biomass gasification from air-steam biomass gasification process. The model aims to investigate: 1) the influences of the gasifier temperature and gasifying agent on syngas production and 2) the operating conditions for methanol production. The results show that higher gasifier temperature and steam to algae ratio increased the syngas yield. The gasifier temperature and steam to algae ratio of 800°C and 0.5 respectively result in the maximum yield of syngas. In the methanol analysis, the operation at high pressure and low temperature enhances the methanol production. The temperature and pressure of 200°C and 80 bar respectively result in the maximum yield of methanol (76.56%).","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134236668","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 unbalance input voltage is divided to three case studies in this paper: C-A couple phase, A-B couple phase and B-C couple phase from threephase system. In addition, a design of transformer shape core occurred on the corner that is the intersection between vertical core and horizontal core with 5mm radius curves. The simulation results compare magnetic vector potential between the original shape of transformer core and the new design of transformer core even though the supplied voltage are unbalanced.

In this work, we propose and develop a methodology to formulate energy benchmarking for the industry. We investigate the energy benchmarking for three sub-sectors of plastics which comprise plastic packaging (plastic bags, bottles, sheet/sacks), household technical plastics, and construction plastics. The energy benchmarking is established based on specific energy consumption (SEC) in the process. The study results reveal the difference both in SEC levels and the ranges of SEC of various subsectors. The outcome of the research shows that the plastic bottle has the widest range of SEC between 0.18 and 3.35 kWh/kg. In contrast, the narrowest variation of SEC is in the construction and plastic bag. Two these sub-sectors also have a lower medium of energy efficiency index, at 0.48 and 0.49 kWh/kg, respectively. From the energy benchmarking results and the sub-sectors scale, the estimated energy-saving potential of the plastic bag is fingered out as the highest energy potential group at 148 million kWh.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133349370","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 establishment of a microgrid can enhance the integration of renewable power, resiliency, reliability, and efficiency. This paper evaluates the technical viability of developing a microgrid system that includes a mix of renewable and conventional energy along with suitable energy storage facilities for application in an Omani island. Models of different renewable energy systems are presented to evaluate their energy production. Economic indices, such as the net present cost (NPC) and levelized cost of energy (LCOE) are utilized to analyze the economic performance of the proposed microgrid system. Five different microgrid scenarios are designed, and their economic, operational, and environmental performance are evaluated and compared. Two system architectures, namely, microgrid utilizing a mix of renewable energy sources and renewable-conventional energy mix microgrid, are proposed. The HOMER Pro Microgrid software is utilized in this study to size, simulate, and optimize the microgrids. The NPC and the LCOE for a renewable-only mix (wind-PV-BS) microgrid are 108.3 million US dollars (USD) and 0.189 USD/kWh, while for a renewable-conventional energy mix (wind-diesel-PV-BS) microgrid with energy storage they are 63.6 million USD and 0.108 USD/kWh, respectively. A wind-diesel-PV-BS microgrid achieves a lower NPC and LCOE than the diesel-only, wind-diesel-BS, or PV-diesel-BS microgrid systems. A thermal load controller is introduced to the microgrid models to verify the impact of excess electricity and to better utilize the microgrid capacity. The outcomes of the sensitivity analysis indicate that a microgrid using a renewable-only mix will become cost competitive if the increasing trend in the price of diesel and the decreasing trend in the cost of renewable technologies persist.","PeriodicalId":247617,"journal":{"name":"International Journal of Smart Grid and Clean Energy","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114785732","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}
