The primary frequency controller may induce an error in frequency regulation, which affects the load sharing accuracy among microgrid distributed generators (DGs). Therefore, a centralized secondary controller is designed to converge the frequency to its nominal value for grid-forming inverters. Using an advanced communication channel, the proposed primary and secondary controller can primarily restore the frequency during disturbances, such as DG on/off switching and loading system variation. The practicality and performance of the proposed controller have been demonstrated with MATLAB simulation environment on a mesh microgrid system consisting of four parallel DGs-based inverters. Simulation results show the proposed controller’s robustness in the microgrid frequency stability. Hence, it achieves accurate active power sharing with a linear load. Moreover, the impact of resistive and inductive line impedance is discussed in this study. A comparison between the microgrid centralized controller (MGCC) and the decoupled trigonometric saturated droop controller (DTSDC) only is conducted to show the robustness of the presented controller performance.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125774754","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}

One-dimensional solar cell capacitance simulator (SCAPS-ID) codes were used to model and analyze the HTL-free CsGeI3 PSC as a constructive technique. The photovoltaic performance parameters of the proposed PSC, such as open circuit voltage ($mathrm{V}_{mathrm{o}mathrm{c}}$), short-circuit current density ($mathrm{J}_{mathrm{S}mathrm{C}}$), fill factor (FF), power conversion efficiency, and quantum efficiency, are evaluated at different thicknesses, doping concentrations, and operating temperatures. The impact of back-contact on the HTL-free $mathrm{C}mathrm{s}mathrm{G}mathrm{e}mathrm{I}_{3}$ cell has also been analyzed. The thicknesses of the ETL and the absorber have been optimized to be 25 nm and 1500 nm, respectively, for enhanced PV performance. As a result of the proposed HTL-free $mathrm{C}mathrm{s}mathrm{G}mathrm{e}mathrm{I}_{3}$-based PSC, a power conversion efficiency of 14.27% was obtained along with a $mathrm{V}_{mathrm{o}mathrm{c}}$ of 1.23 V, a Jsc of 16.45 $mathrm{m}mathrm{A}/mathrm{c}mathrm{m}^{2}$, and an FF of 78.22%.

The energy emitted by the sun can be used as a form of renewable energy, namely solar energy. One of its implementations is to use a series of photovoltaic (PV) cells that can convert solar energy into electrical energy for everyday life. Indonesia is one of the countries located on the equator, which causes an overall temperature that is relatively higher than the world’s average temperature. This high temperature brings the high potential for Indonesia to cultivate solar radiation (solar energy) as a renewable energy source. The construction of solar power plants in Indonesia can help in the distribution of electrical power to meet the country’s power needs. In this study, the examiner will solve a problem in the use of energy in the surrounding environment, by building solar power plants in Indonesia. This research will conduct analysis based on simulations using RETScreen and PVSyst software. The result obtained from PVSyst is that in the selected location, around 42,500 units of Longi Solar monosilicone 415 Wp 34 V type LR4-72-HIBD 415 M Bifacial modules with 7 inverters installed on above 97,234 $mathrm{m}^{2}$ modules area can export 23,877 MWh whereas using RETScreen, the cost needed to build the solar power plant is about ${$}$ 28,998,750 with 47,500 units of Longi Solar monosilicone type LR6-72PH-370W modules on 92,055 $mathrm{m}^{2}$ modules area that can export 23,094 MWh.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"438 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116018505","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}

Disturbances are external factors that affect the state of the system, such as friction and gravity in dynamical systems. They have unexpected effects on the system response, and in the worst case, they cause the system to become unstable. Disturbance observers exist as controllers to suppress such disturbances. However, disturbance observers treat all disturbances that affect the system as input disturbances, which is not strictly true for nonlinear systems. Therefore, we propose a controller that directly considers disturbances to the internal state of the system and suppresses them more rigorously by using left-coprime factorization based on operator theory. Furthermore, we propose a control system that simultaneously performs target value tracking and disturbance suppression with a single controller by combining this theory with an existing control system using right-coprime factorization and double-coprime factorization. Simulation and actual experiments on a linear motor have confirmed that the designed control system has the two performance features of target value tracking by the existing right-coprime factorization and disturbance suppression by the proposed left-coprime factorization.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129767537","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}

Coaxial antenna is used to transmit heat energy from power supply to cancerous tissues. High accuracy energy transmission is very crucial in order to ensure less energy is lost to surrounding or reflected back to antenna. High accuracy of transmission could be achieved if the impedance matching between coaxial antenna and cancerous tissue is good. In this work, the impedance of coaxial antenna is changing by tailored the dielectric material of insulator in the coaxial antenna. Newly developed dielectric composite material is used because of the feasibility to change the dielectric properties only by changing the composition of material used. The permittivity of developed composite material based on epoxy resin and barium titanate is 6.8 while the loss tangent is 0.04 which is suitable to be used as insulator in the coaxial structure. Based on simulation result of coaxial antenna, an improvement in transmission coefficient can be observed with the value of return loss is -63.84 dB. This indicates the heat energy is able to be transmitted with only 0.0004% loss.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126555223","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, in order to realize the efficient utilization of distributed generation, it is generally connected to the grid. Converter is one of the main ways for distributed generation to connect to power grid. This paper discusses the control strategy of grid connected inverter. The dual-vector model predictive direct power control for grid-connected inverter improves the fixed output voltage vector, high grid-side current distortion rate, large reactive power pulsation and other problems when the single-vector model predictive direct power control is adopted. However, the two-vector model predicts that the amplitude of the output vector cannot be adjusted when the two vectors are both effective, and the active power pulsation is still large when only the reactive power is controlled by the deadbeat control. Aiming at these deficiencies, on the basis of its proposed a grid inverter three vector model to predict the direct power control strategy, the control strategy will be two effective voltage vector and a zero voltage vector in a control cycle, makes the output vector direction and amplitude are adjustable, and the active and reactive power no beat control way of vector function to calculate the time, The control precision is further improved. The simulation and experimental results show that compared with the direct power control predicted by the single vector model and the double vector model, the direct power control predicted by the three vector model for the grid-connected inverter has lower current harmonic content, smaller power pulsation and stronger robustness.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131523961","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}
