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.","PeriodicalId":428784,"journal":{"name":"2022 IEEE/IAS 58th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"37 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":"129210735","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 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.","PeriodicalId":428784,"journal":{"name":"2022 IEEE/IAS 58th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"1 2 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":"122172217","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 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.

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.","PeriodicalId":428784,"journal":{"name":"2022 IEEE/IAS 58th Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"6 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":"122980941","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}

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

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.","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}
