This study investigated the feasibility of using a wind energy harvesting in a nano-grid road lighting system. A two-blade Savonius wind turbine was installed on a traffic island to generate electrical energy from vehicle movement. The wind flow velocity stemming from the movement of different vehicles and affecting the wind turbine was analysed by computational fluid dynamics method using ANSYS software. The economic feasibility of using various energy harvesting systems for solar, wind, and piezoelectric energy for a nano-grid road lighting system was evaluated. Further, the optimisation between different renewable energy sources and storage systems for the nano-grid road lighting system was performed using HOMER Pro software. The results showed that the electrical energy production using wind velocity from vehicle movement was feasible, although the wind velocity was unstable. An economic evaluation revealed that the use of piezoelectric energy systems was unfeasible owing to their high investment costs compared to their power generation. The behaviour of power generation from renewable energy and load consumption significantly affected the size of energy harvesting and storage systems. Therefore, the mismatch between solar energy and road lighting system consumption increased the size of solar and energy storage systems, leading to low economic feasibility. In contrast, the hybrid solar–wind system demonstrated great economic feasibility.
本研究探讨了在纳米栅格道路照明系统中使用风能收集的可行性。在交通岛上安装了一个双叶片Savonius风力涡轮机,通过车辆运动产生电能。利用ANSYS软件,采用计算流体动力学方法分析了不同车辆运动对风力机的影响。在纳米栅格道路照明系统中使用各种太阳能、风能和压电能量收集系统的经济可行性进行了评估。此外,利用HOMER Pro软件对纳米网格道路照明系统的不同可再生能源和存储系统进行了优化。结果表明,在风速不稳定的情况下,利用车辆运动产生的风速发电是可行的。一项经济评估显示,使用压电能源系统是不可行的,因为与发电相比,它们的投资成本高。可再生能源发电的行为和负荷消耗显著影响能量收集和储存系统的大小。因此,太阳能与道路照明系统消耗之间的不匹配增加了太阳能和储能系统的规模,导致经济可行性低。相比之下,混合太阳能风能系统显示出巨大的经济可行性。

To maximize the reactive power support from a wind power plant (WPP) and maintain the power factor (PF) at the point of interconnection (POI) within acceptable limits, an adaptive droop coefficient-based WPP controller is proposed in this paper. The controller consists of a central WPP controller and a local wind turbine generator (WTG) controller. An integrated power factor controller enables the central WPP controller to regulate the power factor at the POI under normal operation. An updated droop coefficient model considering the depth of voltage deviations and the range of reactive power capability enables the controller to push the WTG more towards its maximum reactive power limit. For accurate estimation of the maximum reactive power capability, a comprehensive model considering a wide range of limiting factors has been used. To ensure faster and robust operation, both the central WPP controller and local WTG controller are operated in the voltage control mode. Additional reactive power is exported from the grid side converter (GSC) through a developed GSC controller. The effectiveness of the proposed controller is validated through case studies in MATLAB/Simulink environment.
为了使风电场的无功功率支持最大化,并使并网点的功率因数(PF)保持在可接受的范围内,本文提出了一种基于下垂系数的自适应风电场控制器。该控制器由中央WPP控制器和局部WTG控制器组成。集成的功率因数控制器使中央WPP控制器能够在正常运行时调节POI处的功率因数。更新的下垂系数模型考虑了电压偏差深度和无功能力范围,使控制器能够将WTG推向其最大无功极限。为了准确地估计最大无功容量,采用了一种考虑了多种限制因素的综合模型。为了保证更快和鲁棒的运行,中央WPP控制器和本地WTG控制器都以电压控制方式运行。从电网侧变流器(GSC)输出额外的无功功率,通过开发的GSC控制器。通过MATLAB/Simulink环境下的实例研究,验证了所提控制器的有效性。

Several types of hidden faults, like arcing and leakage faults along with the short circuit faults, are common in spacecraft power systems. They pose severe challenges threatening the mission success. In this paper, a multi-layered ring bus dc microgrid architecture is used for the design of space exploration vehicle and surface power systems, due to its enhanced reliability of critical loads and high-power density. Layer interconnecting intelligent three tie contactor units (ICUs) are proposed at every microgrid layer interconnecting nodes, which share the status of their contactors with all the local ICUs and source converters in its layer. Using this information, the local ICUs installed at each node in a microgrid layer use a peer-to-peer communication based adaptive protection scheme to detect and quickly isolate any hidden high impedance or short circuit fault in its layer. The proposed protection scheme is tested with the simulation of multiple fault scenarios in the microgrid using the MATLAB model.

Recently, greenhouse gas emissions have reached their highest level, and many policies are being pursued worldwide. In order to cope with the climate crisis, we are pursuing strategies such as energy conversion and carbon emission reduction, creating a low-carbon industrial ecosystem, and strengthening the carbon neutral system. This paper presented the simulation method and study for the optimal reduction of carbon emissions in residential areas by analyzing data on carbon emissions from different energy sources and adjusting the ratio of use by energy sources. Each energy source consists of simulation of adjusting the hourly carbon emissions and the ratio of use by energy source according to the amount of energy generated and generated. The reduction of carbon emissions per area was analyzed by adjusting the ratio of power generation and carbon emissions by energy source. By reducing carbon through this method, we suggested alternatives and realizations for carbon neutrality.

The Electricity Price Forecasting (EPF) is essential to the bidding strategy formulation and the market operation. However, lack of data and volatility of power generation have put forward new challenges for EPF. To address this problem, we propose an online self-adaptive forecasting method based on random forests. Our approach takes possible fluctuations of the market into consideration, and adapts to them by maintaining training sets of different size. A case study using actual electricity market data has shown that our proposed approach obtains higher accuracy as well as sheds light on possible concept drift in the market.

This work proposed a model and the procedures of deterministic and probabilistic forecasts, e.g., hour-ahead and day-ahead, for wind power generation. The contents of this research include numerical weather prediction, data pre-processing technique, and forecasting models using artificial intelligence methods. Regarding the inputs of the model, we had considered three kinds of NWP wind speeds, generated by the Central Weather Bureau based on three atmospheric models, namely WRFD, RWRF and WEPS, and historical wind power generation. The measured wind speeds, out of an anemometer tower, were used to compare with the NWP wind speeds to help us select the least error time combination. Regarding data pre-processing, NWP wind-speed correction based on the height of wind turbines and PCA and EMD for exacting wind-speed feature had been tested. As for the forecast model, we used artificial neural network and XGBoost to predict the generation of wind power, and a number of error indexes had been used to evaluate the performance of the forecasts. The empirical data from a wind farm in Taiwan verifies the accuracy of the proposed method. What worth mentioning, the importance of model selection, numerical weather prediction, and data pre-processing is self-evident.

As the penetration of photovoltaic (PV) solar generation increases, numerous residential and commercial solar PV systems without meters are being installed. The majority of these systems, however, are not monitored by power system operators. Therefore, the uncertainty of net load owing to these invisible solar power generation will raise additional challenges for power system operation. To reduce the above-mentioned impact, this work proposes a novel method to estimate the total solar power generation in a large region from a small representative subset. The proposed method is capable of capturing all relevant information that assists in the identification of representative subsets. Moreover, different optimization algorithms are utilized and evaluated to select the optimal number of clusters and representative subsets. As a case study, the power generation of 166 PV sites in Taiwan was collected and analyzed. The proposed method demonstrates a significant improvement in estimating the aggregated power generation compared to other existing studies.
随着光伏(PV)太阳能发电的普及,许多没有电表的住宅和商业太阳能光伏系统正在安装。然而,这些系统中的大多数都不受电力系统运营商的监控。因此,这些隐形太阳能发电所带来的净负荷的不确定性将给电力系统运行带来额外的挑战。为了减少上述影响,本文提出了一种新的方法,从一个小的代表性子集估计大区域的太阳能总发电量。所提出的方法能够捕获有助于识别代表性子集的所有相关信息。此外,利用并评估了不同的优化算法来选择最优的聚类数量和代表性子集。以台湾地区166个光伏电站的发电情况为例,进行了数据收集和分析。与已有的研究相比,该方法在估算聚合发电量方面有了显著的改进。

Intelligent Three Tie Contactor Switch Unit based Fault Detection and Isolation in AC Microgrids 基于智能三通接触器开关单元的交流微电网故障检测与隔离

Fault current levels vary in microgrids due to the plug-and-play nature of distributed energy resources (DERs) having different operating modes. This results in maloperation of time-graded overcurrent relay-based protection schemes in an ac microgrid. A higher penetration of DERs or microgrid islanding reduces the fault current contribution from the upstream section of feeder. This condition disrupts the coordination between protective devices operating with pre-defined I-t curves. To address such protection mis-coordination issues, a novel protection scheme that integrates an intelligent three tie contactor unit (ICU) at each DER node is proposed. The ICUs facilitate detecting the operating mode and network topology through their in-built peer-to-peer communication capability. Strategically, each ICU estimates the fault current level in its protection zone and autonomously updates the I-t curves of associated reclosers/breakers. The ICUs limit the synchronous generator-based DERs infeed at the zone of fault and facilitate the inverter-based DERs to ride-through while operating in volt-reactive power mode. It would ensure effectiveness of the existing time-graded overcurrent-based protection coordination for selectively isolating the fault. After the selective fault isolation, the local DERs re-synchronize and operate in parallel with the rest of microgrid system.
由于分布式能源(DERs)的即插即用特性具有不同的运行模式,微电网中的故障电流水平有所不同。这将导致交流微电网中基于时间梯度过流继电器保护方案的误动作。较高的DERs渗透或微电网孤岛降低了馈线上游部分的故障电流贡献。这种情况破坏了与预定义的I-t曲线操作的保护装置之间的协调。为了解决这种保护不协调问题,提出了一种在每个DER节点上集成智能三tie接触器单元(ICU)的新型保护方案。通过内置的点对点通信能力,可以方便地检测设备的工作模式和网络拓扑。策略上,每个ICU估计其保护区内的故障电流水平,并自主更新相关重合闸/断路器的I-t曲线。在电压-无功模式下运行时,配电单元限制了同步发电机式配电系统在故障区域的进给,并促进了逆变器式配电系统的通过。这将确保现有的基于时间分级过流的保护协调对故障的选择性隔离的有效性。选择性故障隔离后,局部der重新同步,并与微电网其余部分并联运行。

The ICUs limit the synchronous generator-based DERs infeed at the zone of fault and facilitate the inverter-based DERs to ride-through while operating in volt-reactive power mode. It would ensure effectiveness of the existing time-graded overcurrent-based protection coordination for selectively isolating the fault. After the selective fault isolation, the local DERs re-synchronize and operate in parallel with the rest of microgrid system.","PeriodicalId":428784,"journal":{"name":"2022 IEEE/IAS 58th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"105 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":"116465842","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}

Power system disturbances can damage electrical components or even collapse an interconnected power grid. The accurate estimation for the disturbance magnitude is critical in ensuring the reliability of the power grid and protecting electrical components. To address this issue, this paper proposes a machine learning approach to estimate the disturbance magnitude. This approach combines the estimations of the conventional approaches to provide a more accurate estimation. Evaluated with the confirmed cases in western interconnection and field-collected measurements from FNET/GridEye, the proposed method achieves 91.2% accuracy on magnitude estimation, which is 7% better than the conventional approaches. Moreover, the proposed method does not require a complex system topology, which makes it adaptive to various sizes of power systems.
电力系统的干扰会损坏电气元件,甚至使相互连接的电网崩溃。准确估计扰动幅度对于保证电网的可靠性和保护电气元件至关重要。为了解决这个问题,本文提出了一种机器学习方法来估计干扰的大小。该方法结合了传统方法的估计,以提供更准确的估计。结合西部互联的实测数据和FNET/GridEye的实测数据,该方法的震级估计精度达到91.2%,比传统方法提高了7%。此外,该方法不需要复杂的系统拓扑结构,可以适应各种规模的电力系统。

This work presents a fault location method in distribution systems based on neural networks using a phase-angle jump as the model’s single input. The IEEE 34 nodes system was used. Different fault scenarios have been considered to train ANN models including various incipient angles, fault types, fault resistance values, and various fault distances that typically affect a fault location algorithm’s accuracy. Different load conditions were not considered in this particular study. Nine different models were trained specifically with particular fault types and fault resistance values and one model was trained with all fault scenarios regardless of the latter obtaining the best performance with three different models trained specifically for locating each fault type considered.
本文提出了一种基于神经网络的配电系统故障定位方法,该方法采用相角跳变作为模型的单输入。采用IEEE 34节点系统。考虑了不同的故障场景来训练人工神经网络模型,包括各种初始角度、故障类型、故障电阻值和各种故障距离,这些通常会影响故障定位算法的准确性。在这个特殊的研究中没有考虑不同的荷载条件。针对特定故障类型和故障电阻值专门训练了9个不同的模型,并考虑针对每种故障类型专门训练了3个不同的模型,无论后者是否获得最佳性能,都对一个模型进行了所有故障场景的训练。
