Due to its geolocation, solar energy has the highest concentration compared to other renewable resources. Harvesting electrical energy from these resources necessitates the use of newly developed renewable technologies such as wind turbine, solar panel and water turbine. In addition to being new, the technology has a low rate of power generation, making it unsuitable as a major energy source. In this work, solar energy has been chosen as a source to help support the energy demand of an university mosque. Matlab/Simulink has been used to simulate the photovoltaic system and generate current against voltage (I-V) and power against voltage (P-V) graphs using mathematical modelling approach in order to measure the maximum point of the output data which is crucial for this research. Due to heat loss, the I-V graph indicates that current varies slightly as temperature rises, but voltage decreases and the P-V graph shows that when the temperature is low and the solar irradiation is high, higher power output is produced. The power output data was extracted and tested in different conditions and the percentages of the support power outputs obtained are within the desirable range for this study.","PeriodicalId":446258,"journal":{"name":"2021 11th International Conference on Power and Energy Systems (ICPES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115136520","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 can not only realize the continuous reconstruction of three-dimensional system of single material and the automatic reconstruction of starting and stopping root material by using the presence or absence of monitoring sensor of material in on-line non-stop state; At the same time, the basic size, deformation size and smoothness parameters of the reconstructed model are calculated In order to calibrate the center position deviation of materials with different sizes, reduce the influence of position information on the dimensional accuracy of material reconstruction, and increase the automatic correction function of center position. This design can supervise and feedback the processing effect of materials processing, and provide effective data reference for the further processing of materials and the reasonable combination of processing procedures. This design can improve the automation degree of processing and the quality of processed materials.","PeriodicalId":446258,"journal":{"name":"2021 11th International Conference on Power and Energy Systems (ICPES)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122979027","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 is necessary to establish a simulation model of HTS cable which can reflect the quench characteristics. According to the structural characteristics of HTS cable, this paper presents a method for calculating superconducting cable parameters based on branch model. The strong coupling relationship among the resistivity, critical current density and temperature of HTS tape after quench is analyzed, and the quench resistance calculation method based on cyclic iteration is proposed. On this basis, the simulation model of HTS cable which can reflect the time-varying characteristics of quench resistance is established by PSCAD software.

However, the use of traditional energy to assist operation leads to more cost and environmental pollution. This paper investigates a tie-line power control strategy of islanded microgrid cluster based on the coordinated operation of thermostatically controlled load (TCL) and battery without any traditional energy, which is mainly divided into two aspects: fluctuation suppression and energy scheduling. In the step of fluctuation suppression, the power fluctuation is divided into high-frequency and low-frequency component. The air conditioning power is controlled by TCL control algorithm to smooth the high-frequency component. Then eliminate the low-frequency component in the tie-line power by controlling the energy storage (ES) device. In the step of energy scheduling, this paper advances a suit of energy scheduling strategy with completely renewable energy supply, so that islanded microgrid cluster stably operates in a certain period of time through coordinated control.","PeriodicalId":446258,"journal":{"name":"2021 11th International Conference on Power and Energy Systems (ICPES)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132543331","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}

Thus, monitoring the CO and CO2 dissolved in transformer oil is considered by the power industry as an important means to ensure the safe operation of power systems. This work proposes the measurement of the CO and CO2 dissolved in transformer oil using Raman spectroscopy and generalized regression neural network (GRNN). Firstly, 200 samples were divided into training sets and test sets. After that, Raman spectroscopy as the input of GRNN, and The concentration of CO and CO2 dissolved in transformer oil as the output of GRNN. Afterwards, the experimental method was incorporated to get the best smoothing factor σ for GRNN. Then, the GRNN with the best smoothing factor σ=24 was trained with the training sets, and the model was verified with the test sets. The experimental results show that the prediction accuracy of the prediction model of the CO and CO2 dissolved in transformer oil based on GRNN is 90%.
