This study investigated an environmentally friendly method for biodiesel production from refined rice bran oil (RRBO) using calcium oxide (CaO) from eggshell waste as a catalyst via transesterification reaction. A two-level three-factor full factorial experimental design was used to determine the effect of the impregnation of silver nanoparticles (AgNPs), calcination temperature and heating rate as independent variables on the biodiesel yield. Results showed that the calcination heating rate and the impregnation of AgNPs had significant effects on the biodiesel yield. An optimum biodiesel yield of about 92% was obtained using AgNPs impregnated CaO catalyst prepared from eggshell waste using a heating rate of $5^{circ}displaystyle mathrm{C}/min$ during calcination at temperatures in 800-$1000^{circ}mathrm{C}$ range.","PeriodicalId":140641,"journal":{"name":"2020 4th International Conference on Green Energy and Applications (ICGEA)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126549906","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}

A kind transformer coupled three-phase three-port 3L-NPC IBDC was put forward in this paper, and two operation modes were analyzed in detail according to the phase shift ratio and the duty cycle relationship. The regulating strategy of power flow for the three-port 3L-NPC IBDC was to get the minimum loss, hence the zero averaged power in the storage port and/or the zero-power flow between the storage port and load port were applied. The control was the multi-loop negative feedback of output voltage and current at the load port and a single-loop feedback of output current at the storage port. The linearization small signal mode was set up to analyze the control property and to determine the parameters. The three-port 3L-NPC IDBC can improve the electromagnetic compatibility obviously for high-power high-voltage application.","PeriodicalId":140641,"journal":{"name":"2020 4th International Conference on Green Energy and Applications (ICGEA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127997937","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, with the popularization of PEVs, low-efficiency supporting facilities such as the charging system impede its future development. To improve the charging system, we focus on plug-in hybrid electric taxis (PHETs) as they are the main users of public charging system. In this paper, we first predict the order numbers and mileage consumption of orders with the help of convolutional neural networks (CNNs). We then divide the area into 30 groups using K-means method and plan the charging capacity of station in each area. Two coordinated dispatching and charging strategies are proposed considering the states of charge (SOCs) at vehicle level and considering the real-time effect at region level, respectively. Finally, we test the dispatching effect using order car ratio (OCR) models at region level. The results show that it works quite well when testing on the real dataset. This method provides optimal instructions for PHETs to pick orders, satisfy their charging demand and also meet the order demands for taxis.","PeriodicalId":140641,"journal":{"name":"2020 4th International Conference on Green Energy and Applications (ICGEA)","volume":"261 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132495671","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}

Aiming at the problem of DC overvoltage suppression, this paper proposes a new control strategy to suppress the rise of DC voltage by adding DC voltage signal to traditional constant AC voltage controller. Firstly, the mechanism of DC overvoltage is studied, and the relationship between the DC voltage and the unbalanced power in DC power grid is qualitatively and quantitatively analyzed according to the law of energy conservation. Then the relationship between the DC voltage and AC voltage is obtained, and an additional DC voltage control strategy is proposed for constant AC voltage control to suppress the rise of DC voltage. Based on the PSCAD/EMTDC, the simulation model of four terminal VSC-HVDC is built. In the case of blocking fault at the receiving end, the effectiveness of the proposed control strategy is verified.","PeriodicalId":140641,"journal":{"name":"2020 4th International Conference on Green Energy and Applications (ICGEA)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129742818","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 uncertain factors have a significant impact on the operating state and harmonic level of power system. To analyze the influence of the uncertain factors, a novel probabilistic power flow method combined the improved point estimate and maximum entropy theory is proposed in this paper. To relieve the calculation burden, the estimated points are first calculated in the standard normal distribution space. Through the transformation from standard normal probability distribution space to the original probability distribution space, the raw moments can be easily calculated. Then according to the raw moments of output variables, the probability distribution of output variables can be reconstructed through maximum entropy theory. The proposed method can effectively analyze the fundamental and harmonic state of the power system. The superiority of the proposed method is validated by the simulation with the IEEE 33 bus distribution system.","PeriodicalId":140641,"journal":{"name":"2020 4th International Conference on Green Energy and Applications (ICGEA)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129299678","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}

One of the units in MASARO is plastic refinery, which handles plastic film waste and turns it into fuel. This refinery unit produce smoke and water as waste. A study is done in the aspect of environmental safety and health, focusing on the analysis of the smoke and the waste water. The analysis showed that all aspects from gas meet the environmental standar, but the height of the chimney need to be made higher for about 5 m.
