The function of load peak shaving and valley filling is achieved, thus ensuring the safe and orderly operation of the rural power grid.

In this case, the energy generated by the PV arrays may be significantly reduced, which will shorten the service life of the PV modules and ultimately increase the overall cost of PV power generation. The mismatch of PV modules stems from the uneven aging of the modules, PSC (partial shading condition), dirt, tracking system failure and so on, among which PSC is one of the main reasons. In addition, the temperature of the PV modules in the shadow will be increased and produce hot spots, which in turn may damage the PV panels. PV reconstruction technology has certain advantages in solving the PSC problem. However, the PV reconstruction algorithms developed so far have some limitations. Therefore, this paper uses the genetic algorithm to design an optimal reconstruction method with fast convergence speed, strong global search ability and higher stability to improve the power generation efficiency of PV array.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123312043","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}

In this paper, the design considerations of it are presented, and the comparisons between the two power supplies are discussed. The calculation results show that the power supply based on HTS machine has much larger power density than the conventional HIA, and the efficiency is also larger than the conventional HIA.

To address this problem, this article proposes a cascading failure risk assessment method for CPPS based on an event-driven model, which provides technical support for risk warning and security analysis of CPPSs. The proposed method involves the establishment of a state transition matrix of CPPS based on a dynamic Bayesian network and analysis of the triggering law of cascading faults. A dynamic HMM model and a set of expected risk scenarios of CPPS are established based on the observable results of physical system faults by the information system. Furthermore, the corresponding multi-index risk assessment model of CPPS is established to describe the risk propagation ability of the system in its operation state, followed by the migration of the operation mode according to the adjustment of the high-risk event-driven control strategy. Finally, the effectiveness of the method is verified using the IEEE-39 system.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121460859","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}

Through the simulation result of different modulation models, it can be concluded that when periodic frequency modulation is adopted, the harmonic of output current signal is no longer concentrated at the switching frequency, and the harmonic amplitude is reduced; the sawtooth periodic frequency modulation has better effect on current harmonic suppression. In addition, the current harmonic optimization effect can be improved by reducing the modulation ratio of periodic frequency modulation, if the spread spectrum width is set reasonably, the frequency expansion range and the harmonic amplitude will decrease.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127005827","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}
