The study is carried out at various high PV penetration levels and wide range of set values of the controller. The response of the power system after sudden successive changes on the controller reference values is observed. The variations of the system operating points have also been outlined. In all cases, the numerical simulations are conducted using the complete nonlinear dynamical model in d-q stationary reference axes. It is concluded that the power system can withstand the variations of the AVR set voltages resulting in a wide range of system running conditions. It is worth mentioning that changing the reference voltage of the AVR does not only affect the operating conditions of the synchronous generator but also largely impact the running conditions of the PV generator.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115663381","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 approach is based on the energy consumption pattern of the household, where energy sources are interchanging to meet certain loads at different time-of-use periods - energy utilization. The combination of a battery and flywheel energy storages is considered in this study, and flywheel energy storage is prioritized to supply high power peaks while the battery is expected to supply low wattage rated appliances. However, the effect of load fluctuations and transient stability can affect the operation of a proposed energy control system if certain technical operation measures are not considered. To overcome these challenges, there is a need to monitor the level of power during load inactivity to improve the precision of the load monitoring technique and apply same for enhancing energy utilization of the hybridized energy storage systems. In this paper, an intelligent Sugeno fuzzy controller is applied to monitor the level of load power at different time intervals and controls the energy flows between the battery and the flywheel energy storages. Furthermore, the flywheel improves the battery state of health by 33.9%.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126146503","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 study focuses on the effect of the number of glass covers on SAHs behavior. The isotropic diffuse model is utilized to calculate the effective transmittance-absorptance product, while the energy balance equation is employed to estimate the thermal efficiency. The hourly and monthly meteorological data for Amman, Jordan is adopted to generate the results. Increasing the number of glass covers has a positive effect represented by decreasing the overall heat loss coefficient and a negative influence characterized by decreasing the effective transmittance-absorptance product. These opposite effects result in an optimal number of glass covers that achieves the highest heater performance. Based on the model in this work and operational conditions for Amman, the optimal number for glass covers is two.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122098982","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 proposed model was applied to a case study in five Burkina Faso regions to produce heat, electricity, and briquettes from crop residues (cotton stalks) and agro-industrial residues (cashew nut shells and mango pits). The obtained results indicate that the optimal technologies are briquetting plants for the production of briquettes and the best biomasses are agro-industrial residues.

Some of the energy sources used to develop these vehicles are batteries and fuel cells (FCs). However, in some scenarios, FC cannot guarantee the energy required for life in the long term. Electricity storage systems (ESSs) are suitable candidates for solving FC transient response problems. The proposed storage system consists of Ultra Batteries (UBs). The combination of FC and UB in electric vehicles is called FCBEV. The energy consumption model of a FCBEV is adopted by considering the power losses of various components, such as the fuel cell, electric motor, the state of charge (SOC) of the battery, and breaks. This paper aims to theoretically study a method to improve the efficiency of FC batteries, by implementing a reinforcement-learning energy management strategy (EMS), pursuing this scope through the optimization of the hydrogen fuel consumption per 100 km. The performance of the FCBEV proposed is verified through numerical simulations, mainly performed under MATLAB environment, over driving cycles.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128676917","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, fast charging systems are crucial for the success of the commercialization of EVs. These systems are heavily reliant on having highly efficient charging stations to reduce the charging time. An EV charger with high total harmonic distortion (THD) can affect both the charging time and battery life. In this research, the Vienna rectifier was adopted due to the low THD, high power density, and high efficiency. Employing Matlab/Simulink software with two simulation scenarios, the proposed Vienna rectifier using the voltage-oriented control technique was implemented and simulated. Charging the EV battery using a constant current controller (CC) at different values and charging the battery directly without the controller are the two scenarios. The simulation results showed that the proposed charger is capable of providing fast charging with low THD allowing the battery to be charged in a shorter charging time less than 15 minutes.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134114520","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}
