Therefore, the voltage stability, power coordination and distribution of the DC grid and the load switching shock the DC grid. Those problems have become increasingly prominent. At the same time, problems such as a large voltage drop at the end and DC grid failure have affected the stable operation of the load in the LVDC(Low Voltage DC Grid). Therefore, this paper proposes a Smart Energy Converter with Distribution and Storage Integrated(SECDSI), it controls the power electronic converter, energy storage equipment and LVDC grid as a whole. The basic topology and intelligent control strategy of the SECDSI will be introduced in this paper. The designed SECDSI can smooth the DC bus fluctuation, maintain the stable operation of the DC grid, reduce the instantaneous current spike of DC load switching, supplement the voltage drop at the end of the grid, and provide the terminal load with seamless switching of uninterrupted power when the DC grid faults. This paper firstly analyzes status and the problems of the LVDC distribution grid. Secondly, design a SECDSI to sole these problems. Then analyze the working principle and control method of the SECDSI. Finally, the function of the SECDSI is verified by the experimental prototype test. The test result shows that SECDSI can effectively suppress voltage fluctuations and provide uninterrupted power to the load when LVDC grid fault.","PeriodicalId":394287,"journal":{"name":"2020 5th International Conference on Power and Renewable Energy (ICPRE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117333990","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}

According to the system design requirements, the paper established relevant mathematical models and analyzed the main factors affecting the motor speed, including the mathematical models of variable pumps and variable motors. At the same time, using the AMESim simulation platform, a simulation model that is consistent with the experimental parameters of hydraulic transmission and control power generation is established to establish a theoretical basis for the study of control algorithms. Through the simulation model, the influence of different input and interference signals on the motor speed is analyzed. Combined with the functional requirements of ocean current power generation equipment, the hydraulic conversion control power generation equipment control system was researched and parameter designed. The control system takes variable motor constant speed control as the core and converts the disordered input natural flow energy into hydraulic energy. Adopting feedforward adaptive control algorithm, and using the steeples speed regulation of the hydraulic system, the novel distributed generation system realized the constant frequency power generation of the generator rigidly connected to the hydraulic motor.","PeriodicalId":394287,"journal":{"name":"2020 5th International Conference on Power and Renewable Energy (ICPRE)","volume":"240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123002095","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}

Solar power is one of sustainable and clean energy sources. Abounding type of solar power is photovoltaic PV, so it needs to be integrated into the utility grid to reduce the amount of burning fossil fuel, which causes the pollution problem. Besides, different DC voltage levels, in the medium voltage bus (MVB), are needed to fulfil the customer expectation and to harvest the solar power into Future Renewable Electric Energy Delivery and Management (FREEDM) system. Therefore, this paper discusses the integration of PV power with the main power grid via reciprocating bus based on power electronic transformer (PET), because PET can provide galvanic isolation instead of using the bulky conventional line-frequency transformer. Moreover, it can be controlled. Reciprocating bus is created by changing the connection of PETs in the secondary side to provide different voltage levels 10KV and 20KV in the MVB. 20KV bus is used to integrate the PV power to a main grid; in fact, it can feed the load from the solar power and from the grid at the same time. Rewarding of using PET is small, efficient and cheaper as compared with power transformer. Simulation results validate the effectiveness and superiority of proposed diagram; the results are verified by PSCAD / EMTDC software.","PeriodicalId":394287,"journal":{"name":"2020 5th International Conference on Power and Renewable Energy (ICPRE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123851118","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}

Considering the propagation process of lightning current along the high tower, an improved simulation model of back striking was established by using the electromagnetic transient program, and then the lightning withstand performance of back striking under different conditions for the ± 1100kV UHVDC large crossing line were studied. The results show that comparing with the conventional transmission line for the ±1100kV UHVDC project, the large crossing section has a much lower lightning withstand level of back striking (LWLBS); The LWLBS for the large crossing line with high tower is not significantly affected by the footing resistance, while enhancing the insulation level can effectively improve the LWLBS. Furthermore, the LWLBS increases with the increase of the distance between striking point and the tower when lightning strikes the large crossing overhead ground wire.","PeriodicalId":394287,"journal":{"name":"2020 5th International Conference on Power and Renewable Energy (ICPRE)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129620294","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}
