In the meantime, with the gradual improvement of the electricity market, the user-side electrochemical energy storage scale also shows a rising trend year by year. This paper first studied the operation mode of electrochemical energy storage on the user side, quantitatively analyzed the profitability and payback period of the arbitrage model of peak and valley power price, and concluded that the peak-valley price arbitrage model has better profitability in areas with large power price differences. Meanwhile, this paper also explored the influence of user-side electrochemical energy storage on the new energy consumption level. Through establishing a year-round hourly production simulation model and an electrochemical energy storage model, we calculated and analyzed the actual conditions of power grid, and studied the new energy consumption status in different scales of user-side energy storage. Through calculations, we found that the configuration of energy storage on the user side could improve the level of new energy consumption to a certain extent, but the improvement effect is limited, and we also found that if the scale of energy storage is increased, then under the current peak-valley price policy, the curtailment rate of new energy may increase, for which we analyzed the relevant reasons, and put forward corresponding suggestions.","PeriodicalId":250053,"journal":{"name":"2021 4th Asia Conference on Energy and Electrical Engineering (ACEEE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127474967","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 randomness and volatility of wind and photovoltaic power generation have brought challenges to the safe and stable operation of the power grid. The power system will require large-scale energy storage as a flexible resource to participate in regulation to maintain the safe and stable operation of itself. As a clean, carbon-neutral, and multi-functional secondary energy carrier, hydrogen will play an important role in the flexibility adjustment of a high-proportion renewable energy power system. Therefore, it is of great significance to study the adaptability of hydrogen energy storage in power systems. This study compares the adjusting characteristics of hydrogen energy storage with other energy storage in terms of regulation technology characteristics.

Therefore, how to design a reasonable structure to reduce circulating current loss of the low-voltage side parallel winding has become an essential issue. Based on the problem, the paper researches on the transposition of low-voltage side winding of the 500kVA/5000Hz high-frequency transformer. With the flux linkage as an intermediate parameter, a transient field-circuit coupling model of high-frequency and high-voltage transformer is established, and branch current balance coefficient and current unbalance degree of the three transposition structures are calculated as the optimal solution measurement index. The results show that circulating current in the winding is not affected by the reactance height, and has a general qualitative relationship with the number of parallel conductors, winding thickness and operating frequency, which provides a theoretical basis for design of the parallel winding structure of high-frequency transformers. According to the comprehensive consideration of three transposition structures based on the measurement indicators, the ‘424 transposition structure’ is the optimal design proposal.","PeriodicalId":250053,"journal":{"name":"2021 4th Asia Conference on Energy and Electrical Engineering (ACEEE)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130751119","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 designed X-Plane VTOL UAV aircraft is used for the detailed simulation and validation of the calculated performance. In X-plane, detailed modeling of individual components is done, and flight tests are performed in different environments for endurance benchmark. A VTOL has five primary flight regimes, namely, take-off, forward transition, cruise, reverse transition, and landing; for all these flight regimes, the state of the charge of the battery is studied.
