Health care systems have been overwhelmed, already destabilized financial markets further jeopardized, with oil and energy markets plunging into crises and economic activities coming to severe halts. To keep people connected while working from home and upholding life-saving facilities in hospitals and around industrial regimes, reliable affordable electricity is imminent. As an immediate consequence of the pandemic, much pressure has befallen countries with low-energy reserves, where the energy sectors involved had already been staggering and facing major challenges ahead of COVID-19. Jordan’s, being of these impacted countries, peak demand on electricity decreased by 17.5% by early April 2020 compared with the mean 2019 levels. Based on the ARMA and ARIMA models obtained, the impact on 2020 electricity demand in Jordan depends on the durations and levels of the confinement/s, with a low estimate of 2.76% if pre pandemic conditions return by mid-September (2020), and a high estimate of 7% if some restrictions remain in effect worldwide until the end of 2020. This article reports the short-term impact of the COVID-19 pandemic on the energy sector in Jordan, with Jordan being a typical example of many such countries worldwide. This will help leverage contingencies and good planning that would help the energy sectors worldwide remain within some sustainable regime/s.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115658785","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 battery in the integrated module is mainly dedicated to store the excess power generated from the PV panel. The battery also operates as a backup power source to compensate for the power mismatch between the source and the load. Therefore, the incorporated management system in the integrated module is necessary for balancing, protecting, and optimizing the lifetime of the battery. The proposed SBMS aims to optimize the battery capacity of each PV panel, provides thermal management strategy, and Master Controller Unit (MCU). MCU is the main controller which includes control algorithm for the 3-port microinverter and estimates the state-of-functions such as state-of-charge (SOC) and state-of-health (SOH) to make the integrated system more secure, reliable, and cost effective. In the paper, the optimum battery size has been simulated, the algorithm for MCU is described with battery model, and the battery modelling and state-of-functions have been theoretically and experimentally verified.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114189336","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 proposed a way to optimize the stator flux switching permanent magnet motor (FSPM) by the introduction of two dual slot additional rotors that are staged 180 degrees apart. The structure, electromagnetic properties and the phase direction of rotation of the proposed permanent magnet machine were investigated at different phase angle. Background study on the mode structure of establishing the proposed topology of one stator and two rotors instead of the conventional one rotor for the motor operation was done. With attention paid to the losses on the stator and rotor, finite element method was used to establish the structure of the proposed permanent magnet machine. The load simulation of the electromagnetic properties was investigated using FEMM 4.2 and Ansys Maxwell to show the advantages of the proposed machine topology to allowing higher electric loading to increase power density in electric vehicles.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125386975","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 least square method is used to establish the models and determine their empirical coefficients. In order to evaluate the performance of the established models, three statistical error tests were introduced, root mean square error, RMSE, mean absolute percentage error, MAPE, and correlation coefficient, R2. The obtained results indicated that the weather condition is fair during May-September, and scattered clouds during the other months. The results also indicated that the sunshine duration-based quadratic model presented the best efficiency for estimating the monthly average of daily global solar radiation on a horizontal surface, where it had the highest value of correlation coefficient, and the smallest values of MAPE and RMSE of 0.93, 2.8049, and 0.0195 kWh⁄m2 ⁄day, respectively.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129592819","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}
