However, the uncertainties originated from the RDG pose challenges to the reliable operation and real-time management of microgrid. To cope with this problem, this paper proposes a real-time economic dispatch strategy of the microgrid by combining the model predictive control (MPC) and robust optimization (RO). The proposed robust MPC based strategy formulates the MPC optimization as a robust problem, which enables the real-time energy dispatch of the microgrid while ensuring its reliable operation. Meanwhile, the feedback update mechanism of MPC contributes to reduce the conservativeness of RO. In addition, the proposed solution considers the demand response (DR) of electricity load to further reduce operating cost. The effectiveness of the proposed solution is demonstrated by simulation experiments and comparison with the benchmark.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129668288","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}

With the development of multi pulse rectifier technology, conventional 36 pulse Transformer Rectifier Unit (TRU) requires a phase-shifting transformer with multiple windings on the secondary side and six groups of rectifier bridges, which has the disadvantages of complex structure and large voltage loss. In order to solve this problem, many scholars have carried out research on pulse multiplication technology. In this paper, based on the small capacity capacitor and autotransformer, an auxiliary auto fed half bridge circuit is proposed. By extracting the DC side pulse for ripple injection, the triple pulse multiplication of the 12 pulse TRU is achieved, and then a new 36 pulse TRU is constructed. The working principle, three modes and input/output performance of the new 36 pulse TRU are analyzed, and the turn ratio of the auxiliary autotransformer is optimized. The structure, composition and performance of new 36 pulse TRU and conventional 36 pulse TRU were compared. The results show that new 36 pulse TRU based on pulse multiplication technology has good performance, effectively simplifies the structure, and reduces the input side harmonic content and output ripple.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127091298","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}

Therefore, it is an important prerequisite for accurate single-phase grounding fault routing to obtain the change law of electrical energy information under different fault states. In this article , by establishing the simulation model of single-phase grounding fault in distribution network, we simulate and analyze the change law of electric energy information under 10 Ω, 100 Ω and 1000 Ω fault grounding resistance, and the results show that: with the increase of fault grounding resistance, the current amplitude of fault phase gradually decreases and the voltage amplitude gradually increases. Fault grounding resistance from 10 Ω to 1000 Ω process, the fault phase current amplitude from 476 A to 32.72 A, the current amplitude reduced by about 14 times. The fault phase voltage increases from 7.317 kV to 9.852 kV, and the voltage amplitude is close to the normal working voltage.

Thus, it is necessary to research the automatic control method of the energy storage device for wind turbine generators that considers new energy consumption. First of all, considering the impact of the temperature of the working environment on the charge and discharge of the energy storage device, an improved second-order RC model of the energy storage device for wind turbine generators was designed. In the model, the impact of the terminal voltage on the charge and discharge of the energy storage device for wind turbine generators was described by controlling the series connection of the voltage source for voltage control and the fixed capacitor. Secondly, an ultra-short-term forecast model of wind power was designed based on the IGA-ANFIS algorithm for the ultra-short-term forecast of wind power for wind turbine generators. Finally, an automatic control strategy for the energy storage device was designed. Based on the actual state of charge of the energy storage device, the charge and discharge power in different areas was adjusted given the new energy consumption. The testing results showed that the MAE and RMSE of the grid-connected power indicators in this method saw a larger decrease compared with those under normal operation conditions, and all the decrease values fluctuated around 0.1.
