The potential of databases in energy forecasting is explored by using big data-driven methods. In this paper, we introduce the variational modal decomposition (VMD) to determine the best model for short-term PV power forecasting by comparing the accuracy between VMD and different combinations of models. Each model uses recursive multi-step prediction at the high level and one-dimensional convolutional networks, as well as long short-term memory networks (LSTM), bidirectional long short-term memory networks (Bi-LSTM), and attention mechanisms at the low level. We evaluate the performance of each model strategy by comparing their mean squared error and mean absolute error against the actual values. The final results show that the VMD decomposition method proposed in this paper has the best prediction accuracy in the combined CNN-Bi-LSTM-Attention model.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"505 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":"115158031","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}

Since the traditional undirected fault location algorithm has the limitation on the number of fault location and electrical power sources, the paper proposes a centralized fault localization algorithm based on the matrix operations. The algorithm solves the difficulty of locating multiple faults in the complex distribution network, and eliminates matrix multiplication with heavy computation. The corresponding diagrams of the distribution network are presented to verify the effectiveness of each algorithm and clarify the scope of application. In addition, the principles of failback are illustrated with practical situations encountered in the process of restoring power supply to non-fault areas.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"15 12 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":"127661428","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}

A two-layer optimization model is used in capacity optimization planning. The outer model deals with PV output and load through multi-state theory to establish a capacity optimization model under an uncertainty framework, while the inner model considers operational costs and energy storage life loss during operation.

Power system stabilizers are commonly used to enhance system stability by improving damping and suppressing low-frequency oscillations. However, optimizing PSS parameters is a challenging task that typically requires extensive analysis or on-site experimentation. To address this challenge, this study proposes an efficient parameter optimization method for PSSs using the DIgSILENT PowerFactory software and the particle swarm optimization algorithm. The proposed method is validated on a 39-node system, and the results show that the proposed method improves system damping and enhances stability.

Therefore, a compound structure based on PIMR (proportional integral multi-resonant) is proposed. Although the PIMR controller based on the RC (repetitive control) internal model architecture has improved speed and anti-disturbance, due to the RC core architecture, the system has a delay of sampling period $N$, so the PIMR-ORC(odd repetitive control) architecture is proposed. PIMR-ORC can provide high gains at the fundamental frequency and its odd harmonic frequencies, which reduces the delay link by half, so PIMR-ORC has a wider bandwidth and faster response speed. However, PIMR-ORC's control effect is barely satisfactory under the fluctuation of the grid frequency. Therefore, this paper proposes a double fractional implementation of PIMR-ORC on the basis of PIMR-ORC and renamed as Fractional Compound Odd Repetitive Control(FC-ORC). Through the fractional approximation of the compensation link $z^{m}$ and $N$, the FC-ORC is more adaptable to the change of the grid frequency. The paper analyzes the stability of FC-ORC and gives MATLAB/Simulink to demonstrate the effectiveness and feasibility of the reform plan.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"13 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":"134113909","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}
