There are many advantages for the connection between offshore wind farms and electricity grid via a high-voltage direct current (HVDC) system. HVDC transmission systems help wind farms provide frequency regulation and voltage control, which have more flexibility compared to HVAC transmission systems. Several control methods for frequency support have been developed. However, few works compared various control methods for a HVDC-connected offshore wind farm.This work proposes a detailed comparison on the main frequency-support control methods for the HVDC-connected offshore wind farm. These controls are mainly based on the communication-based schemes and the coordinated-based methods. The communication-based scheme uses communication devices to transfer the information of grid frequency to an offshore wind farm directly. The coordinated-based methods transfer the dynamic information of the DC voltage on HVDC via generator emulation control (GEC), and then enable the voltage source converter (VSC) at the wind-farm side to supply frequency regulation. In this work, the synthetic inertial control of wind turbines is considered, which include inertia and droop controllers; furthermore, the capacitors of the HVDC system can release the stored energy to help wind farms for the frequency-regulation function.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116768588","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}

A typical wire-to-plate AC-SDBD actuator to control airflow alongside a flat dielectric plate has been considered. A sinusoidal high voltage of varied frequencies and amplitudes is supplied to the 300-micrometer diameter active electrode, and the passive electrode is encapsulated inside a dielectric plate. Two-species ion transport model, involving generic positive and negative ions, coupled to electrostatics model is assumed. The electrostatic field is affected by both the space and the surface charges. The surface charge is accumulated due to ion deposition, but its distribution varies due to the surface ohmic conduction. The Navier-Stokes equations for the flow simulation, which include the time-averaged electrohydrodynamic (EHD) body force determined from the discharge model, are solved to analyze the flow field and the boundary layer morphology. The numerical algorithm has been implemented in COMSOL commercial package. The significance of the dielectric surface conductivity on the discharge behavior and the flow field has been shown. The dielectric surface conductivity behaves non-monotonically and affects the flow field by altering the EHD force strength, direction and distribution.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124307138","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}

Microgrids can help accommodate for the problems that accompany PV systems, such as intermittency due to weather, by coordinating different distributed energy resources (DERs), while islanded or by drawing power from the utility while in grid-connected mode. An islanding option is also important for resilience and grid fault mitigation, even if other DERs are not present within the system. This paper studies the potential benefits that a multi-MW utility-scale PV farm may yield for a large rural community when installed within a grid-connected microgrid structure. The PV system was optimally sized based on net present cost (NPC) with a net zero energy (NZE) goal. With local solar PV generation and a connection to the grid to transmit overgeneration through, the community can be NZE by having a PV farm power rating that is much greater than the peak load demand. This may lead to cases of increased transient severity during mode transitions and may require substantial curtailment of PV. A control scheme is proposed to smooth system transients that result from the switching between the two modes of operation in order to avoid system damage or unreliable load service.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123616663","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 proposed system works by directly cooling the CPU on each server. To uniformly remove the heat from the CPU surface, the heat sink has been redesigned with heat pipes to transfer the heat to water channels which results in a more efficient cooling system. Thus, less water will be needed than a traditional liquid cooling system. This makes the new system more ecofriendly and cost effective. Furthermore, a smart android-based temperature control model is incorporated to adjust the water flow rate of the cooling system and remotely monitor the thermal condition of the CPU. A data acquisition system is utilized to capture the thermal status of the CPU. Accordingly, a digital pulse width modulated switching signal is generated to control the supply voltage of the pump in order to optimize the water pumping power. Thus, the overall efficiency of the proposed cooling system is significantly improved compared to other conventional cooling systems.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131326627","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, transformerless inverters with conventional topologies suffer from leakage current problem which needs to be handled carefully. In order to overcome the conduction loss and leakage current problem associated with conventional transformerless inverters, a new transformerless H6 (6-switch-based) inverter topology is proposed in this paper that can maintain constant common mode (CM) voltage while reduce or eliminates the leakage current problem. The proposed inverter topology is simulated using MATLAB/Simulink software to validate the accuracy of the proposed system. The effectiveness of the proposed topology is verified through the comparative results of CM voltage, CM leakage current and conduction loss of the proposed topology with the conventional H6-I, H6-II and H5 topologies. Finally, to validate the proposed topology, a laboratory prototype is also built and tested. The experimental results validate the theoretical analysis and simulation results.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121107206","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}
