In this regard, this paper proposes a dynamic priority-based communication scheduling strategy for the PD-IoT to meet the communication needs of different applications. Firstly, a multi-priority application queuing model is established based on the application communication value, and the average queuing time of the edge IoT gateway for processing and forwarding the PD-IoT application data is calculated to provide a theoretical basis for application scheduling. Then, a communication scheduling strategy based on dynamic priority is proposed. A dynamic priority factor is introduced based on the application remaining value density and the urgency of execution, added by a preemption threshold set under the application preemption mechanism. Finally, it is verified through OPNET simulation that the communication scheduling strategy proposed in this paper can not only take into account the communication needs of different PD-IoT applications, reduce the processing delay of information collection applications, but also improve the overall reliability and efficiency of communication when massive application data is accessed.","PeriodicalId":115453,"journal":{"name":"2022 5th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"368 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123949348","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}

Many countries require wind power generation to be capable of offering a fast frequency response (FFR) when deviations in power system frequency occur. Because the FFR covers a short duration, the wind speed variation during this period has been largely ignored in previous studies. In this paper, we paid attention to the wind speed variation rule within a 15 s time frame. By analyzing the measured data of a wind farm, we found that the wind speed variation rule within 15 s can be clustered into six categories, among which the probabilities of continuously rising wind speed and continuously falling wind speed are the two with the largest values, 37.68%, and 37.49%, respectively. The change of wind power in the 15 s time range usually does not exceed 40%. Subsequently, we analyzed how the various wind speeds affect the FFR of the wind turbine generator (WTG) with combined virtual inertia and droop control. The simulation results suggest that there is little difference in the WTG response within the first 3 s of the FFR whether the wind speed change is considered or not. However, there is a significant difference in the response of the WTG with or without considering the wind speed variation in the subsequent time. Therefore, to study the FFR control of the WTG or to accurately evaluate the effect of the FFR, the wind speed variation should be considered.","PeriodicalId":115453,"journal":{"name":"2022 5th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115354832","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}

This paper mainly studies the discontinuous modulation method of full-bridge MMC and proposes an implementation method of discontinuous modulation strategy for full-bridge MMC with a mathematical model established based on segmental function, taking advantage of the segmental characteristics of modulated wave of MMC under discontinuous modulation. Discontinuous Pulse Width Modulation (DPWM) makes the switches remain inactive in a specific modulation period, which can improve the equivalent switching frequency, optimize harmonic characteristics and reduce switching loss. The effects of discontinuous modulation strategy on device power losses and modular capacitor voltage is analyzed on the basis of the mathematical model. Then, the effects of discontinuous circulation on device power losses and modular voltage is analyzed by combing the discontinuous modulation strategy and circulation injection strategy. Simulation is conducted and verified that the MMC loss and modular voltage fluctuation can be reduced by the circulation injection strategy under discontinuous modulation.","PeriodicalId":115453,"journal":{"name":"2022 5th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123467964","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, the environmental crisis, pollution of the seas, and the depredation of marine resources have significantly decreased the productive capacity and profitability of artisanal fishermen. Therefore, new economic opportunities are beginning to be explored based on tourism, specifically fishing tourism, which revalues and explores artisanal fishermen's culture and knowledge. The present research performs the design, installation, and evaluation of a system of photovoltaic panels on an artisanal fishing boat as part of the adaptation that allows the development of tourist activities, which require the supply of electrical energy so that various equipment can function and effectively offer communication services, entertainment, food, comfort, and safety. The tests at sea demonstrate that it is possible to supply the new energy demand generated by tourist activities. The tests were carried out in winter (pessimistic conditions), and even so, it is possible to satisfy a demand for four tours, one of them at night.","PeriodicalId":115453,"journal":{"name":"2022 5th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116076734","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}
