A number of methods have been introduced to model the nonlinearity existed in the control model. Predictive control which is a model-based control method is one of the advanced control methods in practical applications because it can be implemented in time-domain, and easy constraint handling during the design process, as well as the capability of implementing multi-variable systems. A linearized Volterra model for NMC can be proposed to convert the nonlinearity of the system into a series of linearly equivalent expressions. Obtained results show that linearized Volterra series can effectively model dynamic non-linear systems which further allowed employing the proposed model for predictive control. The results reiterate that the use of the Volterra series is comparatively simple and promising in terms of non-stable system modeling.","PeriodicalId":6768,"journal":{"name":"2020 IEEE International Conference on Power and Energy (PECon)","volume":"60 1","pages":"415-419"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84462748","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 presents a robust maximum power point tracking (MPPT) algorithm which is able to work under any level of PSC efficiently, accurately, rapidly and with no increase in complexity. The proposed algorithm employs the composite trapezoidal rule to locate the actual maximum power based on trapezoidal area estimation concept, with the assist of adaptable step size perturbation and observation (P&O) algorithm. Complex PSC levels have been chosen to guarantee the validity of the suggested algorithm to perform under any shading level. The simulation results approve the effectivity of the algorithm under three various cases of complex PSCs, and compared with performance of the conventional Perturbation and Observation (P&O) and Incremental Conductance (IC) MPPT algorithms. The results indicate the success of the proposed algorithm, and the weakness of the conventional algorithms in seeking the actual maximum power under PSC which is the global maximum power point (GMPP).","PeriodicalId":6768,"journal":{"name":"2020 IEEE International Conference on Power and Energy (PECon)","volume":"11 1","pages":"270-275"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75419615","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 idea was derived from the great property of glass, such as transparency, high mechanical surface strength and good dielectric property that is predicted to replace the conventional and silicon semiconductor material as the substrate for an RF energy capture. Aim of the study is to develop MEMS patch antenna that should be compatible with 180 nm CMOS process. The antenna device consists of a substrate, slotted petal conductor, ground plane and impedance matched output slot. The substrate is made of pyrex glass and fabricated using a surface micromachine process technique. The fabricated device is then measured in an anechoic chamber and compared with other antenna made of silicon and standard conventional antenna substrate. The results show that the patch antenna on glass performs similar to the conventional antenna fabricated on RT/Duroid that show very promising alternative substrate material for an energy harvester system where size, weight, cost, performance, ease of installation and fabrication are constrains.","PeriodicalId":6768,"journal":{"name":"2020 IEEE International Conference on Power and Energy (PECon)","volume":"180 1","pages":"362-365"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77355486","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 reluctance variation faced by secondary magnet flux due to primary slotting and end effects produces detent or cogging force, which results in high force ripples, noise and vibrations. This effects the smooth starting and controllability of the machine in accurate positioning applications. This paper proposes some design modifications in the primary slots and slot-openings of LPM machines for detent force minimization. The effect of various design modifications on cogging force, average electromagnetic force and force ripple has been studied using 3-D Finite Element analysis.

These DG infiltrations altered the classical grid architecture hence affecting the grid protection structure specifically in related to the islanding situation. Unintentional islanding brings serious threat to the maintenance personnel in charge of the islanded grid, electrical instruments as well as the DG connected in the microgrid. A lot of researches were already conducted and continuously done in the chase of an ideal anti-islanding strategy, whilst the ideal one is yet to be acquired. This paper proposes an islanding detection strategy based on monitoring the rate of change of positive sequence of voltage (ROCOPV). Simulations are conducted for several islanding situations that include the deficit, surplus, and balanced islanding cases, hence the output procured is promising. The ROCOPV efficiently detect all demonstrated islanding cases within 0.05 s without any non-detection zone (NDZ).","PeriodicalId":6768,"journal":{"name":"2020 IEEE International Conference on Power and Energy (PECon)","volume":"30 1","pages":"176-181"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82069667","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}

In the adopted configuration, the LCL filter links a three-level neutral clamped point inverter with the grid. A typical inverter is a source of harmonics as in general its output is not a pure sinewave. Standards such each IEEE 519 and IEC 61000-3-6 define the allowable harmonics distortion for both the current and the voltage in a power system based on the current level and the voltage level respectively. This paper aims to design an LCL filter to reduce harmonics produced by a three-level inverter serving as interface between a fuel cell stack and a grid and meet the abovementioned standards. The input of the grid tied inverter is connected to a 1.4 MW solid oxide fuel cell stack at 1400 V. The inverter is modelled and controlled to deliver 1.2 MW at 600 V between phases. To evaluate the performance of the designed filter, the system including the 1.4 MW fuel cell stack, the inverter, the LCL filter, a grid and a load is simulated using Matlab/Simulink environment. The results show that the designed filter reduces the total harmonics distortion to 0.46 % and 24.87 % for the voltage and the current, respectively.","PeriodicalId":6768,"journal":{"name":"2020 IEEE International Conference on Power and Energy (PECon)","volume":"37 1","pages":"209-213"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84762838","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}
