The model predictive current control method is adopted to replace the PI controller in the current loop of the traditional PWM rectifier. On this basis, the switch state of the rectifier applied under the open circuit fault of the power switching devices is compared with the optimal switch state obtained by model predictive control, and the fault feature signal is established to realize the fault diagnosis and positioning of the charging pile power switching devices. Since the fault feature signals of different power switching devices have no influence on each other, this method has significant effect on single tube, double tube, and multiple tube simultaneously fault. The simulation results verify the correctness and effectiveness of the proposed fault diagnosis method for charging piles.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121052800","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 the digital construction of the quality inspection laboratory, the scheduling algorithm of quality inspection tasks requires higher scheduling efficiency and accuracy to meet the diverse needs of practical applications. Different from the traditional job-shop scheduling problem (JSP), there is no fixed corresponding relationship between samples and tasks in the quality inspection task scheduling problem (QISP), which means a higher degree of freedom of scheduling. At the same time, quality inspection tasks have more complex constraints such as serial, parallel, and mutual exclusion, which makes the existing scheduling algorithms cannot be directly applied. This paper builds a reinforcement learning (RL) based method for QISP. A new scheduling feature representation method is proposed to fully describe the state of quality inspection tasks and sample-device utilization. Aiming to solve the problem of sparse rewards, we present a reward function to integrate scheduling environment utilization rate and empty time. Considering the non-repetitive and complex constraints of quality inspection tasks, a set of action selection rules is proposed to replace the agent's direct learning of action decisions. Heuristic decide is used to improve the convergence speed of the algorithm and enhance the interpretability of the model's action selection. Compared with the traditional MWKR, GA, PSO algorithms, the RL-based method in this paper shows great advantages in solution quality and efficiency on the real data-set of a quality inspection laboratory of a state grid corporation.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125116900","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}

However, existing studies have not fully revealed the key parameters of the transient stability of the renewable energy conversion system with the limiters and instability pattern. To fill the gap, a grid-connected VSC system including the current limiter and frequency limiter is first established in this paper. Secondly, the influence of key factors on the transient stability of grid-connected VSC systems with limiters is investigated to conclude the stability forms. The results show that there is no monotonous tendency of influence between transient stability characteristics and key factors, which is significantly different from the results of ignoring limiters. Additionally, due to the limiter, two new stable forms appear, that is, the power oscillation of the peak clipping and the stabilization at the new stable equilibrium point caused by the switch between the control modes. The relevant work in this paper provides a reference to understand the stable features and dynamic behaviors of the renewable energy conversion system.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126809994","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}

However, the uncertainty of the output of photovoltaic power stations has brought an impact on the power grid that cannot be ignored. How to reasonably allocate reactive power is an important guarantee to alleviate this problem. Therefore, an SVG-capacitor joint configuration strategy for photovoltaic power station based on comprehensive cost evaluation is proposed in this paper. First, an equivalent model of the external power grid of photovoltaic power stations is established to simplify the calculation difficulty. Secondly, SVG-capacitor joint allocation strategy for photovoltaic power stations based on the comprehensive cost evaluation is proposed, which takes the minimum comprehensive annual cost of SVG-capacitor configuration as the optimization objective, and takes into account the constraints of grid operation safety, reactive power compensation demand, capacity constraints, etc. Finally, the particle swarm optimization algorithm is used to optimize the solution.
