This paper proposed a novelty and an effective tuning method of dual-loop controller based on lead compensator and proportional (P) controller for single-phase qZSI to ensure reliable DC-link power regulation. Specifically, lead compensator and P controller act as voltage control and current control loop, respectively, to generate the desired shoot-through duty cycle feeding towards the unipolar carrier based pulse width modulation (CB-PWM). The lead compensator contributes to move the system poles from the left to the right half of the s-plane while the P controller damps any high frequency oscillation occurrence caused by the newly sited complex conjugate pole pair. To demonstrate the effectiveness and the feasibility of the proposed controller, the qZSI is utilized as a static synchronous compensator (STATCOM) system to provide reactive current compensation at the point of common coupling (PCC). All simulation models and results which documented in this paper are carried out using MATLAB/Simulink software.","PeriodicalId":278078,"journal":{"name":"2018 IEEE 7th International Conference on Power and Energy (PECon)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127994869","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}

Despite many studies on electrical treeing in SiR with SiO<inf>2</inf> nanofillers, none of the publication have reported on Si<inf>3</inf>N<inf>4</inf> nanofillers for the purpose of the electrical tree growth suppression. By applying a fixed AC voltage of 12 kV at power frequency of 50 Hz, the treeing experiments were conducted on unfilled SiR, SiR/SiO<inf>2</inf>, and SiR/Si<inf>3</inf>N<inf>4</inf> nanocomposites with 1, 3, and 5 weight percentages (wt%) of filler weight concentration and the treeing parameters were observed together with its correlated PD patterns. This study found that among the samples of SiR, SiR/SiO<inf>2</inf> and SiR/Si<inf>3</inf>N<inf>4</inf>, the best nanocomposites to suppress the electrical tree growth is SiR/Si<inf>3</inf>N<inf>4</inf>. Moreover, when the electrical treeing progresses, the PD activity shows increment thus indicating correlation in both parameters which can be a key tool for monitoring unseen treeing in opaque samples.","PeriodicalId":278078,"journal":{"name":"2018 IEEE 7th International Conference on Power and Energy (PECon)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128642076","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}

It was identified that climate factors and an economic factor of hotel occupancy could be used to characterise the regional monthly electricity consumption. This study selects Jakarta, Indonesia as the case study, covering the monthly time period from 2006-2012. Multiple linear regression approach is applied to analyse the association between the continues variables. The computation and visualisation is executed in R. One of the explanatory variables, namely hotel room occupancy, is interesting to be analysed in this case because the case study is the capital of the country. Many national events are being held centrally in Jakarta. In practice, limited studies have used this variable to model electricity consumption. The finding shows that the simplest model is conducted by excluding the variable day of rain and variable rainfall that slightly contribute to the model. The result identifies that the relationship between electricity consumption and hotel occupancy is statistically significant, as well as the relationship between electricity consumption and temperature.","PeriodicalId":278078,"journal":{"name":"2018 IEEE 7th International Conference on Power and Energy (PECon)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129907435","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 pose critical challenges across the world. The renewable energy sources (RESs) provide a viable and sustainable energy alternative which is capable of meeting the exponential energy growth, reducing over-dependency on fossil fuels as well as minimizing global warming. This paper presents an optimal control and management of an autonomous hybrid energy system (AHES) that reliably supplies energy demand at a minimum daily operating cost. The non-linear cost function is formulated as a mixed integer nonlinear programming (MINLP) problem to optimize the use of renewable resources and minimize the utilization of diesel generator (DG). The unpredictability inherent in RESs is addressed through the optimal design and management of multiple energy generation sources, and battery storage system (BSS). The MINLP optimization technique employed is validated with a dynamic commercial daily load profiles. The simulation results show that the proposed hybrid system significantly minimizes daily operating cost and improves supply reliability when compared to DG-single system.","PeriodicalId":278078,"journal":{"name":"2018 IEEE 7th International Conference on Power and Energy (PECon)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125897844","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}

Current trend shows the implementation of precision agriculture system to be used in indoor farming, thus allowing crops to be harvested throughout the year regardless of seasonal changes. However, the main challenge with implementing this system is the high energy consumption of the technologies used in the system. Therefore, this paper presents proof of concept solution to manage the energy consumption of the precision agriculture system by designing a hybrid photovoltaic-thermoelectric generator (PV-TEG) system as a power supply. The hybrid system power output is to be compared to a standalone solar photovoltaic system. A simple mathematical modelling using Matlab/Simulink is done to estimate the hybrid systems feasibility to provide sufficient power to run the precision agriculture system electrical load for a set period of time. An experimental approach will be done to validate the hybrid systems ability to provide power in real time.","PeriodicalId":278078,"journal":{"name":"2018 IEEE 7th International Conference on Power and Energy (PECon)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116741406","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}
