This version of the wavelet modulation technique is structured as a multi-resolution analysis that can support a redundant non-uniform recurrent sampling-reconstruction of three reference-modulating signals. The reconstruction of reference-modulating signals is achieved by sets of resolution-segmented scale-base linearly combined synthesis wavelet basis functions, which are used as switching signals to activate the switching elements of a 3φ, 5L, VS dc-ac PEC. The presented wavelet-modulation technique is implemented in realtime using a digital signal processing board. Switching pulses generated by the extended wavelet modulation technique are used to operate 3φ, 5L, VS, diode-clamped and flying-capacitor dc-ac PECs. Experimental performance of the tested 5L dc-ac PECs is evaluated, when operated by the presented wavelet modulation, level-shifted pulse width modulation (PWM), phase shifted PWM, and space vector modulation techniques. Experimental tests are conducted for linear, dynamic, and nonlinear loads fed by the tested 5L PECs. Test results show that magnitudes of output voltage fundamental components can be significantly increased, and harmonic distortions can be effectively reduced using the wavelet modulation technique. These features are further demonstrated by performance comparisons with other techniques under similar operating conditions.","PeriodicalId":428784,"journal":{"name":"2022 IEEE/IAS 58th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129384782","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}

As the core devices of the DC distribution system, power electronic transformers (PETs) occupy a large proportion of construction cost. For the cost reduction for construction and protection, two types of three-port modular multilevel convertor (MMC) have been proposed in recent years, which are respectively based on dual active bridge converters (DABs) and phase shift full bridge converters (PSFBs). The PETs based on DABs provide high reliability but high cost as well. The PETs based on PSFBs bring a large reduction on construction cost but shows low reliability under the disturbance in the low voltage DC (LVDC) systems. In this paper, a novel PSFB/DAB-MMC topology is proposed with the combination of the above two PETs. The proposed PSFB/DAB-MMC decreases the construction cost with enough reliability under severe disturbance in the LVDC system. A double-modulation-freedom control strategy is proposed for the compatibility of two different types of submodules. The simulation results in MATLAB/Simulink verify the feasibility and the reliability of the proposed topology.","PeriodicalId":428784,"journal":{"name":"2022 IEEE/IAS 58th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"73 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132298977","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}

Current measurement is one of the essential areas where the magnetic effect of current allows magnetic field sensors array to restore information about the characteristics of the power system. Nevertheless, in the parallel multi-conductor current measurement scenarios, sensors usually get interactive interference from neighboring currents, which significantly affects the measurement accuracy. This paper proposes an improved method for interactive rejection. In the new method, the inferior current measurement is utilized to eliminate the interactive interference and update current estimation by emulating the magnetic field. Compared to the traditional method, the new method improves the accuracy without any hardware change. In the numerical simulation, the mean absolute error of 29 A caused by crosstalk is reduced to 0.00068 A in a 3000 A three-phase system.

It can meet the thermal preference and develop an appropriate control air conditioners strategy for each user through the power and environmental data which will not affect their cost and privacy. Combined with this method, a proportional control strategy is presented to optimize the energy consumption, which can also solve the inaccurate human parameters problem caused by difficult acquisition.

Therefore, satellite remote sensing shows its unique significance as an additional stable irradiance observation source. This paper develops a feature importance analysis-based solar irradiance mapping model to calculate ground solar irradiance only using satellite data. In this paper, the K-means method is employed to classify the weather condition. The correlation of all channels data of FY4 satellite with the solar radiation of PV site is analyzed using the Pearson correlation coefficient under different sky conditions. The XGBoost feature important algorithm is applied to analyze the importance of different channel features, which optimizes and determines the input of the mapping model. The gradient boost regression model (GBR) is chosen as the mapping model to calculate solar irradiance with the combination channels satellite data obtained according to feature important analysis.

Yet most research on PV power/irradiance forecasting focus on deterministic forecasting, whereas it is difficult to express the credibility of the forecasting results, especially in the scene of instantaneous fluctuation of irradiance and photovoltaic power caused by cloud movement. Therefore, in this paper, we use the ground-based sky image to accurately estimate and track the rapid fluctuation of solar irradiance and meanwhile considers the uncertain constrained optimization problem to establish a high-quality joint point-interval real-time estimation model, which can not only provide the result points from deterministic forecasting, but also achieve the prediction intervals. The results show that the model can produce tight intervals while simultaneously achieving deterministic forecasting results of high quality and strong robustness, regardless of the weather conditions. Besides, compared with the traditional way of taking the middle position of the interval as the deterministic forecasting result, the performance of our model is greatly enhanced.","PeriodicalId":428784,"journal":{"name":"2022 IEEE/IAS 58th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126517353","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}

To overcome this issue, a novel model predictive control-based voltage and frequency regulation at the Point of Common Coupling (PCC) through DGs in isolated microgrids is proposed. The results of this work are presented in this two-part paper. In Part 1, a data-driven predictive model for DGs is developed and parameterized through the system identification approach using Gauss-Newton (GN)-based Nonlinear Least Square (NLS) method. The polynomial input-output Box-Jenkins model is chosen as the model structure. This model will be further used in Part 2 to implement a Model predictive controller. The proposed model incorporates distribution line parameters into the control algorithm and allows a wider variation of power angle without initiating nonlinearity. Therefore, it can substantially reduce the controller size and complexity, and widen the controller’s operational range.","PeriodicalId":428784,"journal":{"name":"2022 IEEE/IAS 58th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122894496","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}

To counteract these issues, the active damping (AD) based on optimization and sliding mode control (OSMC) with an observer is proposed. The OSMC, synthesized with linear quadratic regulator (LQR), is able to improve the system performance and maintain system stability.

In determining the position of the air-termination system, two methods are generally suggested: the protective angle method and the rolling sphere method. Adopting a 3-D graphical simulation, the “rolling sphere” method allows one: to analyze the protected volume at the building roof inside of the rolling surface; to verify the behavior of the designed air-termination system. The proposed original method of the protected volume section by an air termination system of lightning rods is an alternative to the graphical analysis with the rolling sphere simulation. The protected volume method proposes the mathematical calculation of the prospected profile described by the rolling sphere, and, as simpler first step, allows identifying the minimum protection height useful for a preliminary evaluation of the critical height. As second step, the method defines a shape describing the protected volume section a cautionary model that replaces the circular sector of the rolling sphere with a “vase section” shape. Given a volume to be protected, taking into account the equipment and elements to be protected, the method allows to configure the air-terminal system with rods suitable for the volume protection. In order to avoid the exposure of equipment to direct lightning, the identification of the protected volumes allows highlighting positive situations or those of overruns with respect to the volume to be protected and so taking corrective measures.","PeriodicalId":428784,"journal":{"name":"2022 IEEE/IAS 58th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129890860","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}
