The proposed PTO can be used with any wave energy converter (WEC) type that has a reciprocating linear motion. Here it is deployed in one of floating-structure, direct-extraction type WEC. The magnetic thread is unique in that the components of the PTO can slip harmlessly when overloaded, thereby overcoming a significant disadvantage of direct-extraction technologies that are susceptible to higher stresses.In the chosen floating-structure WEC, the PTO is driven by a point absorber: a buoy working against a reaction plate. A dynamic model representing the control and behavior (mechanical and electrical) of the WEC is developed to accept wave data as an input resulting in an effective output power.A stochastic model that generates a spatial and temporal wave characteristic data set for Banks Peninsula, New Zealand, is developed using available measurements. Different configurations of wave farm are assessed under a condition typical to this location, well suited for such an energy harvesting device. The variability of the aggregate farm output, compared to that of a single buoy, is examined. Reduction in variability is maximized when the outputs of individual buoys are uncorrelated. A criterion that determines the extent of correlation is derived.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128166450","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 cell anode is graphite based, and The cathode of the cell is nickel, manganese and cobalt (NMC) based. Moreover, the surface temperature of the cell is recorded with the use of a thermal camera and thermocouples, then it was compared with simulation results.The experimental results show a rather uniform temperature distribution, with maximal temperature difference of 0.7°C, during the discharge load profile whereas the maximal temperature difference at the end of discharge load was around 1.5°C. 3D thermal modeling simulation results executed at different ambient conditions are compared and validated with the experimental results, wherein the error fluctuates around 2°C. Furthermore, the maximal temperature area was observed at the center point of the battery.Finally, the rose of the temperature in the discharge test was around 22°C at 10°C ambient condition and 20°C at 25°C ambient condition.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122572887","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, sustainability has become a crucial concept to combat extreme consumption of environmental resources. The bathroom has been estimated to be the principal user of hot water for domestic dwellings in United Kingdom. To achieve a highly efficient water and energy consumption in the bathroom, the concepts ‘’smart’’ and ‘’sustainable’’ strategies are fundamental. Therefore, this paper aims to develop an intelligent/smart energy fuzzy logic control for a bathroom system that minimize the energy consumption. This process offers an automatic control of water-flowrate and temperature in the bathroom. The key finding shows that the step response of the system is considerably efficient with minimum overshoot, fast rise time and zero steady state error. The result also demonstrate that fuzzy logic control is efficient in its operation and can lead to a great reduction of energy consumption and subsequently leads to low energy cost.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130095699","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 identified many FRT stipulations under grid fault conditions in various grid codes. The study examines the impact of PVs on the grid code development, offering a detailed and classified viewpoint on the FRT regulations and providing valuable details about the FRT capabilities of a common grid code to be used and referred.
