For heavy duty construction vehicles, electrification consists of two principle components: electric hybridization of the vehicle carrier and the vehicle's auxiliary function. Economic and physical feasibility for the transition to electrical replacements for critical system components is important for the gradual development of electrified systems. In this paper, we present an investigation into multiple pathways for the hybridization of mobile cranes paired with simulations that analyze the feasibility of system electrification. ADVISOR was used to compare the feasibility of hybrid topologies for the vehicle carrier of a crane using approximate emissions, fuel economy, and efficiency. Analysis of the feasibility of transitioning to an electric motor for the crane's auxiliary function was performed using ANSYS TwinBuilder. Issues concerning satisfying the current draw of electric motors for both simulations point to currently available energy storage systems as the main factor hindering the electrification of mobile crane systems without significant redesign due to the initial cost, upkeep, and lack of energy density.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"73 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":"116162151","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}

With the increase in energy consumption in many countries, the efficient use of resources in energy production has gained importance. Integration of renewable energy generation with EV has become one of the new trends for optimal use of Renewable Energy Resources (RES), meeting energy demand, improving grid stability and sustainability. In this paper, energy management of EV charging based on PV system for an Industrial Microgrid (IMG) is presented to provide EV load shaving service and optimize the cost of charging electrical energy. Using the travel behaviors of EVs, daily charging energy is investigated and Monte Carlo Simulation (MCS) based on statistical data is applied to determine driving time for EVs. By analyzing the battery charge properties of EVs, the initial state of charge (SOC) is calculated, and the total charge power and the charging time of EVs are obtained in the analysis. Using the data obtained from 673.42 kWp a solar power plant (SPP) named Harput-SPP, the analysis of 5,000 EV charge loads is developed in the model created on the MATLAB/Simulink software platform.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"15 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":"125288743","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}

Frequency is an indirect measurement that is typically estimated over time using an averaging technique. However, grid events such as phase jumps or faults and changes in distributed generation are sufficient to trigger changes to frequency calculations that could cause incorrect tripping of plant. In particular, fast acting distributed generation or energy storage are known to frequently trip off at the point of common coupling due to rate of change of frequency (ROCOF) protection. A variety of methods have been proposed to improve the frequency estimation or ignore bad ROCOF and frequency measurements during events for use in relays. This paper builds on previously published work with a curve fitting method in conjunction with a goodness of fit calculator to improve the curve fitting process to include the impact of step change events by modifying the curve fit equation. The paper uses real data sets to analyse and compare how the curve fitting works under different grid events. The paper shows that this method offers an advantage over traditional methods of frequency determination and would minimize tripping of distributed generation and energy storage systems on ROCOF settings as they ramp up and down quickly.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"8 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":"121283525","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 studied stills are then compared to those studied in the Middle East and North Africa (MENA), China and India, to determine their suitability in SA. The study further looks at the extent to which SA has implemented solar thermal technologies and their future prospects.

However, some technical aspects remain unsolved and currently slow down its progress, such as the formation of tars in the gas stream. Accurate measurements of a gasifier's operational parameters are central to improve the process' performance and enhance its understanding. It is with this premise that an instrumentation and monitoring system for small scale downdraft gasifier is proposed. The instrumentation system will consist of the measurements of temperature, mass of products inside the gasifier, pressure and air flow, along with actuation of the latter. A chipKIT Max32 microcontroller board serves as the core of the proposed system and act as a link to a computer where the visualization of the process is displayed. A software application was developed in order to concurrently display all the parameters either during operation or using previously acquired data.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"27 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":"133094057","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}

By using the adaptive proportional-integral (PI) control strategy in the dc-link voltage, the improvement is realized by tuning online with a fuzzy logic approach. The main goals are to reach a minimum of dc voltage error during the transient state and assuring a reactive and harmonic compensation in the power grid. Many topologies of DPC strategy are studied in the literature exploiting a simple PI controller. However, due to its fixed parameters, this conventional controller does not work satisfactorily under variable load conditions. This work is deal to investigate the better improvement of dynamic performances and maintain a high power quality of the filtering system. In order to verify the effectiveness of the adaptive PI strategy, computer simulation has carried out under Matlab/Simulink software. The proposed control strategy proves that the system could manage the harmonic compensation and reactive power transfer in an adjustable and dynamic manner.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"26 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":"116751867","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, the poor performance of the MOSFET’s intrinsic diode and the output capacitance present difficulties in voltage source converter bridge-legs. When a MOSFET in this circuit turns on, a charging current has to be sourced into the output capacitance of the complementary freewheeling MOSFET, even if the diode has been deactivated. The peak incoming drain current into the MOSFET turning on can be limited by using a large resistance in series with its gate. However, this increases MOSFET power dissipation. Also, the turn-on propagation delay time is increased.

In the building sector renewable sources and energy efficiency optimization are leading to a large scale employment of nearly-Zero Energy Buildings (n-ZEBs), meaning that the balance between produced and required energy is negligible. For a proper n-ZEB implementation, a power system architecture has to be accurately designed, according to the existing renewable sources, loads and storage systems. In this paper, an investigation on different topologies of DC-DC converters for energy storage management in a n-ZEB scenario is carried out, aiming at the efficiency and power density optimization. The interleaving technique is investigated as well, in order to evaluate its potential benefits according to the specific DC-DC topology.
