In order to solve the problem that the existing methods are inaccurate in the acceptance and assessment of wind and solar resources in the distribution network, it is proposed to comprehensively consider the flexibility evaluation index and the clean energy consumption quality index, and analyze the access capacity of distributed wind and solar resources under the current distribution network structure in combination with the operating constraints. First, set renewable energy output model; Secondly, construct distribution grid flexibility evaluation indexes and clean energy consumption quality indexes that include constraints, and take into account the two objectives of wind and PV resource access capacity and distribution grid operation costs; Finally, taking the IEEE33 power distribution system as the example model, the effectiveness and rationality of the proposed method are verified by comparing the results obtained by comparing the results obtained by three different schemes.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125160218","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 bidding form is introduced into power trading to effectively motivate users to actively participate in the service and expand ideas for the commercialization of cloud energy storage business. First, a detailed cloud energy storage service mechanism architecture and business process are designed. Secondly, a day-ahead power dispatching model and strategy aiming at the minimum net energy cost of the user groups are constructed. Then, an electricity bidding and matching strategy in the form of multiple rounds of collective bidding is established. And the benefits of each participant are clarified. Finally, a park is taken as an example to verify the effectiveness of the proposed service mechanism. The results show that this mechanism can promote the local consumption of renewable energy, reduce the energy cost of users, increase the service engagement of users, and achieve a win-win situation for all parties.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115670767","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 test process requires reproducing the application scenarios of high-frequency transformers and at the same time reducing the power consumption of the test power as much as possible. To this end, this paper designs a DC power feedback type high-frequency transformer temperature field test power supply. The power supply is mainly composed of power frequency AC-DC and back-to-back high-frequency transformers, DC-AC and AC-DC modules. Power diodes and resistors are connected in series with high-frequency AC-DC and DC-AC DC sides to form a DC power feed link. The sum of the high-frequency DC-AC DC voltage and the DC feeding resistance voltage is used as the set value of the high-frequency AC-DC DC voltage output., and the single-phase shift of DC-DC control is adopted to achieve the target current output of the test power supply. At the same time, a mathematical model between the input and output current of the test power supply and the grid-side current is established, which provides a theoretical basis for the energy-saving evaluation of the energy feedback test method. Finally, the test power supply experiment simulation system was built, and the results confirmed the correctness of the test plan.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115793913","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 low voltage direct current supply and utilization system (LVDCSUS) has received much attention from academics and industry in recent years. However, the initial research has not been conducted in the LVDCSUS, including but not limited to operation modes, control strategy, protection, grounding mode. As one of the most important factors in the operation, reliability, and protection configuration of LVDCSUS, the choosing of the grounding mode in the LVDCSUS may influence the transient characteristics of the connecting point of the energy storage and PV generation system, which will determine the operating stability of the LVDCSUS. To provide a guideline to future LVDCSUS grounding mode chosen in different operation conditions, in this paper, the transient characteristics of the DC bus, energy storage port and photovoltaic power supply port of the symmetrical monopole system after the monopole ground fault of the DC bus are analyzed, and the influence of the grounding fault on the power generation and energy storage module operation of the low-voltage DC system is discussed. The research can provide reference for the selection of grounding mode and the configuration of fault protection in the LVDCSUS.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"64 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115823187","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 influence of frequency coupling, the positive and negative sequence impedance is no longer decoupled, and the generalized nyquist criterion needs to be used for analysis, which makes the system analysis complex. Based on this, this paper first modifies the impedance matrix to realize the equivalent transformation from multiple input multiple output (MIMO) impedance matrix model to single input single output (SISO) impedance model. Secondly, for the equivalent SISO system, the nyquist stability criterion is used in the frequency domain to analyze the influence of the system short-circuit ratio, PLL bandwidth, current loop bandwidth and other parameters on the system stability. Theoretical analysis and simulation results show that the system short-circuit ratio increases, the PLL bandwidth decreases, the current loop bandwidth increases, and the system stability improves. Finally, the correctness of impedance model and theoretical analysis is verified by time domain simulation.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130619898","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}
