Then the Nash game theory was used to analyze the bidding strategy of micro grid considering a power market with imperfect competition. We found that the bidding strategy with high proportion factor and low cost quotation of micro grid can maximize the system’s profit. Although the change of any micro grid’s bidding strategy will lead to the adjustment of bidding strategy of other micro grids, the system will eventually achieve Nash equilibrium. Finally, we obtained the optimal bidding strategy and selection scheme of micro grid to maximize the micro grid’s profit through numerical analysis. Introduction Smart grid is considered as the next-generation power network. Its most important aim is to improve the energy efficiency, quality and reliability of the power system. It is also the inevitable result of the innovation and sustainable development of distributed generation and energy storage, advanced power electronics and modern communication technologies [1] . In order to efficiently and reliably manage and operate such an important and complex architecture, the micro grid (MG), as the most important component of smart grid, can integrate and coordinate the distributed MG through the distributed energy resource management platform. Distributed generation (DG) is that the power generation facilities placed directly in the distribution network or distributed near the load, generating electricity economically, efficiently and reliably [2] . Power generation facilities in the distributed generation system are called as distributed power sources including wind power generation, solar power generation, fuel cells, and micro gas turbines, et al. These power supplies usually have a small power generation (typically less than 50 MW) and are close to the user. They can generally supply power directly to nearby loads or output power to the grid as needed. This is called as distributed energy resources(DER) [3] . The efficient introduction of MG faces numerous challenges on many fronts such as design, control, and implementation [4] . Although many programs have been made in the MG generation technology, electricity trades among MGs have received limited attention [5] . In recent years, smart grid pricing related to electricity trades has always been a very important topic. In this field, some researches focused on demand-side management [6-8] . Also, some research studied the pricing mechanism of power market with different bidding models [9-11] . Consider the rapid development of MG technology, microeconomic analysis on power pricing considering a finite number of agents in the power market is important for the success of MG. In this paper, we construct a multi-agent system based power trading market with micro-grid, and investigate the optimal bidding strategy for micro","PeriodicalId":11324,"journal":{"name":"DEStech Transactions on Environment, Energy and Earth Sciences","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80767422","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 large amount of garlic slices processing wastewater was produced every year, which contains garlic oil. In order to recycle and utilize this resource, this paper takes the local garlic slices processing wastewater in Jinxiang County of Shandong Province as the research object, and through \"Microfiltration (MF)+Distillation\". The method of distillation was used to extract garlic oil from garlic slice processing wastewater, and the effect of garlic slice cleaning process on garlic oil yield in wastewater was investigated. The results showed that the yield of garlic oil could reach 0.45‰ under the optimum cleaning conditions. Introduction Garlic slices is an important export agricultural product in China while a large number of processing wastewater are produced in the cleaning process of garlic slices. The discharge of the processing wastewater not only causes great harm to the environment but also seriously restricts the sustainable development of China's garlic industry [1]. The processing wastewater can also cause serious damage to the creatures and the environment. The main components of the garlic oil that cause environmental pollution are the garlic polysaccharides, the allicin and other organic compounds that are of economic value[2]. It is estimated that 17 to 20 tons of water to process per ton of garlic slices and there are 3.36 million tons of processing wastewater of garlic slices each year with the loss of about 30000 tons of garlic polysaccharide and 120 tons of the allicin [3]. The treatment technology of the processing wastewater of garlic slices is still in the research stage. At present, the treatment technology to processing wastewater of garlic slices is still at the stage of study, and there is less research on extracting garlic oil from processing wastewater of garlic slices. Existing extraction methods include organic solvent extraction[4] and resin adsorption[5]. The method of resin adsorption is a new type method of water treatment. It has innovative significance in the extraction of garlic oil, but due to the complex operation and high production costs, it has not been promoted. This experiment summarized existing experimental data, and comprehensively considered various influencing factors, and selected suitable experimental methods to extract garlic oil from wastewater. The garlic oil has antibacterial anti-inflammatory, improve immunity, anti-cancer and other anti-cancer effect, with high medical and health value[6]. In this paper, the experimental study of extracting garlic oil from garlic waste water can extract valuable resources from waste water, and the cost is low, so it has huge economic and social benefits.

These tubes is required to be tested by standard oil burner, which provides an environment of temperature about 2000 °F and heat flux about 11.9 W/m. The purpose of this paper is to achieve a better understanding of the heat transfer process of tube fire test and make prediction on the temperature rise before samples were subjected to the test facility. The flow rate was studied by both theoretical and experimental method to determine its influence on temperature rise. Also, temperature rise of Jet A-1 fuel and lubricant RIPP 4050, which have different fluid characteristics, was used for comparison of the model. The result shows a good compliance between theoretical value and experimental measurements. Introduction Tubes are widely used in aircraft engine nacelles, distributing fuel, lubricant and hydraulic oil to other parts of the aircraft. As the space around engine is a most hazardous zone because of its high temperature and strong vibration, these hose assembly that carries flammable fluid is required to withstand the fire resistance test by airworthiness regulations. Tubes and connectors, no matter whether it’s made of metallic or non-metallic material, is required to be subjected to a standard kerosene flame by certain paragraphs of CCAR23.1183, CCAR 25.1183 and CCAR27.1183. As the type of carrying fluid differs, the flow rate in tubes varies greatly. Fuel distribution tube of some large transportation category aircraft may have a flow rate up to tens of thousands of liters per hour, while flow rate of hydraulic oil tube of some little aircraft may be 100 liters per hour or even lower. Because fluid acts as the temperature reducer for tubes, low flow rate is utilized in fire resistance test to represent the harshest condition for conservative considerations. Theoretical Analysis As the oil flows steadily and continuously within the tube by oil pump, the flow could be seen as a well-developed flow and the distribution of temperature field depends on whether the flow is turbulent or laminal.

SEM images were used to observe the morphologies of ZnO nanorod arrays. The phase structures of ZnO nanorod arrays were characterized by means of XRD. The phenol wastewater was degraded with ZnO nanorod as catalyst. The effects of UV light application time and ZnO nanorod catalyst quantity on phenol removal efficiency were investigated. The results show that the phenol removal efficiency is as high as 70.12% when 5.7 mg ZnO nanorod catalyst is added, pH is 7.3, and UV light application time is 2 h. The ZnO nanorod arrays prepared under the action of pulsed electromagnetic field (PEMF) have greater order than that prepared by conversional hydrothermal synthesis. The catalytic performance of ZnO nanorod arrays prepared with PEMF is better accordingly. Introduction Phenol is a kind of extremely nerve poison and causticity chemical substance, which is harmful to all life-form, especially to aquatic life. The characters of phenol wastewater are non-biodegradable, wide source, and seriously hazardous [1-4] . It is necessary for phenol wastewater treatment to find an effective technology. The treatment methods of phenol wastewater include traditional technology and advanced oxidation processes. However, traditional methods such as physical adsorption, coagulation, chemical oxidation and biological treatment are likely to cause secondary pollution [5,6] . Photocatalysis technique as an important advanced oxidation technology is widely researched in organic wastewater treatment. Owing to the small size effect, high surface effect and quantum size effect, nano particles exhibit excellent characters in catalyst fields [7-12] . Nanometer materials such as titanium dioxide and zinc oxide are usually used as photocatalysts to degrade organic pollutants [7,8,10-12] . Previous research has shown that the degradation effects of phenolic wastewater are satisfied using ZnO nanoparticles or ZnO thin as photocatalysts [12-16] . Especially supported nanometer ZnO is characterized by not easy to run off, easy to recover and separate, no secondary pollution in the process of wastewater treatment. In this study, ZnO nanorod arrays are prepared by the hydrothermal synthesis, and the ZnO nanorod samples are used as catalysts to treat simulated wastewater of phenol. Experimental Main chemicals.

Based on the analysis of the distribution characteristics of the toppling deformation body in a hydropower station reservoir area in southwest China, this paper simulated the relationship between the distribution of river terraces and the toppling deformation body by using the discrete element method, and the conclusion that the influence of river downcutting on the toppling deformation is obtained. Introduction Toppling deformation is closely related to engineering construction, involving water conservancy, transportation, mining and other industries, such as Jinchuan open pit slope [1] , Jinping I hydropower station left bank slope [2] , Xiaowan Hydropower Station drinking ditch slope [3] , Changma reservoir toppling deformation slope [4] , Xiaolangdi reservoir area bank slope [5] , etc. In order to ensure the normal construction and safe operation of the project, it is of great practical significance to study the formation mechanism and stability of the toppling deformation slope. In the 1950s, foreign scholars began to study the phenomenon of toppling deformation. After decades of unremitting research, scholars have made fruitful achievements in the deformation characteristics, genetic mechanism and stability analysis of toppling deformed rock mass. Distribution Characteristics of Toppling Deformation Rock Mass 24 toppling deformation bodies are distributed in the reservoir area of a hydropower station from dam site to reservoir tail within 60 km. There are 20 toppling deformation bodies on the right bank and 4 toppling deformation bodies on the left bank. Due to the influence of regional tectonic activities, the structure of the right bank slope is dominated by reverse slope and slope, while the left bank is dominated by forward slope. According to the investigation, more toppling deformed bodies are found in the position of well-developed gully, and have a larger development range and a larger amount of deformation. Main Deformation and Failure Forms of Toppling Deformation Rock Mass According to the investigation and analysis of the deformation and failure phenomena of the toppling slope, there are four types of deformation and failure of the toppling slope: the toppling bending deformation, the toppling fracture deformation, the toppling tension deformation and the toppling creep deformation.

Then a detailed parametric study is performed for average pressure coefficient of two low-rise gable roof buildings in the same shape which only change the angle of the downstream building. The results show that the mean wind pressure coefficient of upstream building is hardly affected by the angle changing of the downstream building when the distance between buildings is larger than twice of building’s width, while the downstream building is affected relatively large especially at the corner area of ridge at small angles. Introduction It is well established understanding of the failure mechanism and distribution of surface pressure on isolated low-rise building through studies of experts and scholars around the world in recent decades. Such as Zhou and Nie[1] systematically studied the influence of low-rise gable roof building wind pressure coefficient and the surface shape coefficient with different wind attack angle, roof pitch, eave length, eave height, and ratio of wall length to width. Li [2]and Dai[3]did a lot of wind tunnel tests and field measurements about low-rise buildings during typhoons, and some laws that low-rise building’s local surface wind pressure influenced by slope angle and wind direction were summarized. However, low-rise buildings are normally built in large groups and it has complicated wind interference effects among buildings, so some conclusions which came from studying isolated buildings were hard to apply in the practical engineering. Thus some experts and scholars started researching wind field and wind environment about grouped buildings after 1980s and some research results were obtained. Tsutsumiet[4]and Ho[5]discussed interference effect between low-rise buildings and obtained that the influence of wind interference effect was large when buildings built in group, and it should be pay more attention on the research of wind interference effect. Zhao et al.[6]simulated a common two dual-slope roof which in the same shape before and after the light steel plant layout with ANSYS Fluent software, obtained that wind interference should fully considered when the distance between two buildings less than twice the building’s width. Based on software of Fluent 6.3, this study simulated the wind tunnel model of Tokyo Polytechnic University and compared the results to wind tunnel data. Then mean wind pressure coefficient of two low-rise gable roof buildings in the same shape was simulated which only changing the angle of the downstream building, analysed the influence of angle changing to upstream and downstream buildings. It’s expected that the results would provide reference value for studying grouped low-rise buildings.
