However, if a power line trips or if distributed generation is disconnected due to a fault or maintenance, it alters the topology of the power system. Consequently, the magnitude of the fault current also shifts, potentially causing a breakdown in the protection coordination system. It is considerably difficult to protect the power system using fixed setting values. Therefore, this paper proposes an adaptive protection algorithm using the setting groups (SGs) of a numerical protection relay. The number of SGs that a numerical protection relay can contain is limited and less than the number of possible topologies of the power system. The proposed algorithm optimizes not only the setting values of each protective relay but also the combinations of SGs corresponding to each topology. This broadens the searching area for the optimization algorithm, aiding in effectively reducing the operation time of protective relays. The protection algorithm is verified using a modified IEEE 30 bus test system.</p>","PeriodicalId":15577,"journal":{"name":"Journal of Electrical Engineering & Technology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141513106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a situation where rapid power curtailment is required, the conventional power curtailment method of the wind turbine can cause a power imbalance between the electrical energy and wind energy in the wind power generation system. It can cause severe damage to the generator because of overspeed in the wind turbine, which may require stopping power generation even though it can inject power into the grid. Cooperative control can be applied to resolve power imbalance during conventional power curtailment, which uses both the wind turbine’s pitch angle control and the machine-side converter’s current control. In other words, the pitch angle controller calculates the pitch angle for the active power output for the current wind speed conditions, and the machine-side converter calculates the current value for the active power output, so that the suddenly curtailed active power output of wind power generation can be achieved quickly and stably through cooperative control of pitch angle and converter current.

To solve this problem, a multi-objective optimization method considering both the geometric parameters and winding parameters of SPIM is proposed in this paper. Firstly, the key frequency components that contribute greatly to vibration and noise of SPIM are obtained through the vibration and noise measurement of the prototype. Then, the electromagnetic finite element model (FEM) of SPIM is established, and the geometric parameters of SPIM are optimized with the torque, efficiency and amplitudes of key frequency electromagnetic forces as the optimization objectives. After that, the analytical model of SPIM output performance is established, and the winding parameters are optimized with the torque and efficiency as the optimization objectives. Finally, the torques, efficiencies and amplitudes of key frequency electromagnetic forces of the SPIM before and after optimization are calculated by the electromagnetic FEM, and the optimization results are evaluated. The above process can be iterated until the optimization requirements is met. To verify the effectiveness of the proposed method, an SPIM with rated power of 800 W is taken as an example to illustrate the optimization process in detail. The output performance, vibration and noise of the SPIM before and after optimization are measured by dynamometer, vibration acceleration sensor and sound intensity sensor, respectively.

In response to this critical issue, this study presents an innovative approach that harnesses the power of both Recurrent Neural Networks (RNNs) and Generative Adversarial Networks (GANs) to revolutionize power generation forecasting in renewable energy systems. The hybrid model combines the strengths of RNNs, known for capturing temporal dynamics and sequential dependencies, and GANs, renowned for generating realistic data distributions. The results demonstrate a remarkable improvement in forecasting accuracy compared to traditional methods, reducing errors and uncertainties. The hybrid RNN-GAN model enhances the reliability of renewable energy systems, facilitating greater integration of sustainable energy sources into the grid. Furthermore, the research underscores the importance of incorporating a Grid-Connected Hybrid System Design and implementing a closed-loop control framework. These additions ensure that the forecasts are not just theoretical but are actively used to optimize energy utilization and maintain grid stability in real-world scenarios. This innovative approach holds great promise for a greener and more efficient energy landscape, making a substantial contribution to the transition towards a fresher and more sustainable future. The proposed Hybrid RNN-GAN model consistently outperforms existing methods, yielding significantly lower RMSE and MAE values for both solar and wind data, showcasing its superior accuracy in renewable energy generation forecasting. The achieved R-squared (R<sup>2</sup>) values of 0.82 for solar data and 0.7 for wind data at 100 iterations further validate the model's effectiveness in capturing underlying patterns, while skewness and kurtosis analyses affirm its ability to generate predictions aligned with normal distributions.</p>","PeriodicalId":15577,"journal":{"name":"Journal of Electrical Engineering & Technology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141513110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
