The failure of converter valve will cause the outage of the DC transmission, which will cause serious economic losses and even cause major safety accidents. However, the current technology can only make logical judgments on whether the converter valve is in a normal state and cannot judge the health status of the converter valve; and then carry out maintenance and replacement plans for the key components of the converter valve according to the health status. To meet the technical requirements for monitoring the health status of converter valves, the method is carried out on the health status of converter valves for UHVDC transmission. Firstly, a multi-source heterogeneous data acquisition program for UHVDC converter valve status parameters is proposed. After that, a data feature extraction program is invented; combined with the data feature extraction method, a single index and multi-index converter valve health status assessment is carried out. Finally, a feature extraction system for high-voltage DC converter valves was built in the laboratory to verify the effectiveness of the feature extraction function. The test results show that the feature parameters and health status analysis proposed in this paper can effectively extract the features of the converter valve and complete it and analysis the health status of the converter valve.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125119762","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 battery-supercapacitor hybrid energy storage system (HESS) has more advantages than traditional ES system. In order to make full use of the advantages of HESS and realize the reasonable distribution of power, a power distribution control strategy for HESS is studied in this paper. The virtual resistor or virtual capacitor is extended into the control loop of each ES element to change the output impedance of the converter and then the power distribution of HESS is realized. Battery is mainly responsible for the low-frequency part of power fluctuations, and supercapacitor (SC) can quickly respond to the high-frequency part of power fluctuations. The two cooperate with each other to increase the service life of ES equipment and ensure the stable operation of the system. Finally, the correctness and effectiveness of the control strategy are verified by the simulation work in real time digital simulator (RTDS).","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117033042","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}

Photosynthesis Sediment Microbial Fuel Cells (P-SMFCs) is one form of sustainable green energy source which that produced electricity while treating wastewater, although many studies for P-SMFCs are related to its main function as a wastewater treatment unit, there are limited information about the effected factors on the power generation of single chamber P-SMFCs using wastewater as a fuel source. Current study will focus on the affected parameters on byproduct (power generation) such as; electrode distance and location, electrodes surface area, temperature, and cathode aeration. A cylindrical container filled with a gravel filter, the anode and cathode electrodes were fixed on different layers of the filter, as were planting paper plants available and used in previous studies. This system was feed in batch mood with wastewater that collected from Al-Rustamiyah WWTP. Results showed that; Electricity generation performed better when minimize the distance between anode and cathode with maximum voltage of 1050±10mV at 5cm while maximum voltage of 588 ±30 mV at 8cm, Electricity generation is proportional to increase the electrodes surface area, whereas 440 cm2 produced more voltage than 220cm2 and 110cm2 which was (1553±12 mV, 1217±9 mV, and 1050±10mV ) on 10th day respectively, Three temperature values were examined in this study (36,32,25)C° and the beast performance was at 32C° which is related to the suitable temperature value for metabolism process, and Electricity generation dropped from 2074±18 mV to 1884±18 mV when applied aeration to the system.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132801929","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}

Characterize the randomness, intermittentness and volatility of wind power and photovoltaic power units ; refine the peak load regulation of thermal power units into ordinary and deep mode, and refine their economic indicators.
