It effectively traces the grid and load angle utilized for synchronization purpose. The power generation units of wind and PV power are the renewable resources utilized to fulfill the critical load demand under grid outage mode. The battery associated with bidirectional DC-DC converter allows reduction in the battery capacity rating. In fact, effective load current fundamental constituent extraction is carried out using least mean logarithmic square (LMLS) algorithm. It reduces the effect of the non-linear load harmonics on the utility power quality. It also allows sensitive load operation at the point of common coupling (PCC). The microgrid is modelled in Matlab and the simulation result procured, depict the smooth mode transition from utility associated operating mode to utility outage mode and vice-versa. The harmonics appearing in the grid current are eliminated successfully while providing enhanced power quality of grid and voltage of PCC.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"39 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87990495","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}

Despite the numerous advantages, the protection scheme faces the challenge to isolate the internal fault within 5 to 6ms. Moreover, the algorithm also deactivates the relay, to operate during the disturbances and external fault. This paper proposes a protection scheme utilizing Discrete Wavelet Transform (DWT) and Support Vector Machine (SVM) classifier. Several types of faults are created on the HVDC transmission lines using PSCAD/EMTDC. The current and voltage signals of the HVDC line are obtained and decomposed using DWT to obtain the detailed coefficients up to the third level. Features obtained from the detailed coefficients are further used for the training of SVM for the detection and classification of the fault. Since the proposed approach uses only the information from one end, it does not rely on communication. To avoid the high computational burden of the Wavelet transform, the protection scheme is designed in such a way that, it performs the DWT, only if the disturbance persists for five consecutive samples.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"5 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88224931","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}

Specifically, this paper proposes a novel flux-tube based approach to derive closed-form analytical expressions for the effective air-region permeance at the aligned and unaligned rotor positions in terms of machine dimensions. The proposed method does not require preliminary finite element analysis (FEA), and includes the effect of rotor pole height on the flux-linkage characteristics. The predictions by the proposed method for three different machines are compared with the results of FEA and of three existing analytical methods. The results of the proposed method are found to be accurate and comparable to those of FEA in all cases. The aligned and unaligned flux-linkage characteristics of a 10000-rpm, 5-kW SR machine, thus predicted, are verified through FEA and experiments. Correlation between machine characteristics and dimensions, combined with good accuracy and low computation time, make the proposed method a useful tool for design optimization.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"70 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86125388","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}

House boat tourism is the backbone of this sector. Luxurious and climate controlled suites combined with back water transport are the major attraction of these house boats. For both propulsion and indoor amenities, the hydrocarbon based fuels are a key energy resource. The continuous exploitation of fossil fuels, especially petrol and diesel through combustion route as a primary energy source have landed in major contribution of carbon footprints and water pollution. The impact of these activities to climate change will lead to a threat for aquatic life and sustainable tourism. Energy efficiency and renewable energy are the forward players to tackle these challenges. Dependence on reliable and quality power from grid is also a challenge for these house boats during docked as well as sailing conditions. A novel methodology to harvest clean and free renewable energy from roof top Solar Photo Voltaic (SPV) modules, store using suitable energy storage technology combined with energy efficient power distribution using Low Voltage Direct Current (LVDC) to feed energy optimally to the hotel loads is discussed.

Whereas the topology of dual two-level (DTL) inverter is emerged with the provision of dedicated pulse width modulation (PWM) scheme to eliminate the CM voltage and thereby considers the reduction of CM emissions in the system. However, the effect of CM voltage elimination on the attenuation performance of high frequency CM noise (up to 30 MHz) and shaft voltage in DTL inverter fed induction motor is not clearly stated in literature. Thus, this paper presents the theoretical and experimental discussion on comparative evaluation between TL inverter system with passive EMI filter and the DTL inverter under PWM schemes such as CM voltage elimination (CMVE) PWM and remote state PWM (RSPWM) scheme. The comparative evaluation is carried out in terms of attenuation of conducted CM emissions in relevance to the component requirement for both the systems. The experimental verification of the reported work is carried out for a 3-$phi$, 1.1 kW IM driven in star configuration for TL inverter and open-end winding configuration for DTL inverter.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"69 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83480923","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}

For reliable and secure operation of DC microgrid, a new protection scheme based on change in transient reactor voltage at one end of the cable is proposed for fault detection during grid connected and islanded mode of operation. Whenever the magnitude of change in transient reactor voltage observed at one end of the cable exceeds pre-defined threshold limit, an internal fault is detected. The proposed scheme is investigated for different transient and fault conditions such as internal faults at different locations with different fault resistances, external faults, AC side faults, load variation, DG outage and generation uncertainties due to change in environmental conditions to further demonstrate the feasibility and robustness of the proposed protection scheme. The simulation results confirms that the proposed protection scheme is fast, accurate, capable of identifying internal faults and types of faults in DC microgrid.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"11 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84767659","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}

By function, the proposed mode maximizes the building’s use of passive energy strategies through natural ventilation to reduce cooling or heating loads from the Heating Ventilation and Air Conditioning (HVAC) system operation. Simulation studies were performed for three selected residential buildings in Pacific Northwest National Laboratory building stocks varying from mild, warm, and humid-continental climates. The annual simulation results established a minimal number of periods that cooling or heating was needed to supplement natural ventilation. The hybrid control operation established significant heating demand reduction during the winter simulation periods and a widely varied cooling demand savings during the summer across the evaluated climate locations. The operation mode shows a scalable potential for model predictive control functions and other extensive applications in advanced demand management and transactive operations.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"88 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91050388","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}
