Secondly, taking the lowest economic operating cost as the objective function, a PLIES low-carbon economic dispatching model with coupling P2G and CCS is constructed.

However, the insulation performance of RTV coating decreases rapidly due to aging and failure caused by long-term physical and chemical effects such as electric heating and ultraviolet. In this paper, the AC samples of RTV coating in Ningxia power grid were selected for a series of tests. The aging characteristics of RTV coatings with different years were analyzed from the aspects of sample appearance inspection, hydrophobicity, Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The results showed that RTV coating of in Ningxia power grid operates well, and hydrophobicity of the coating surface is remained in HC1~ HC2 level, which meets the requirements of equipment anti-pollution performance. Through FTIR and SEM analysis, it was found that the change of peak area of characteristic functional groups on the inner and outer surfaces is related to the migration of small molecules in the RTV coating, and the cracking of main chain functional groups was the main reason for the aging of RTV coating. Moreover, small molecular substances are easy to enter and stay in the coating due to the rough surface of RTV coating and the heavy pollution characteristics in Ningxia, which increasing the hydrophobicity of the coating surface. The research results will provide a scientific basis for the aging mechanism and insulation performance evaluation of AC anti-pollution flashover coating in Ningxia power grid.","PeriodicalId":227496,"journal":{"name":"2022 3rd International Conference on Advanced Electrical and Energy Systems (AEES)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116487091","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}

Expectation maximization algorithm is utilized for fitting the WHMT to observational data. Then, denoising is accomplished, and Support Vector Machine is utilized to classify the extracted features.

The critical conditions of low frequency oscillation are analyzed by impedance ratio criterion and Bode diagram. Then, power compensation control strategy (PCCS) is used to control the energy storage system. The equivalent model of electric locomotive-traction network coup-ling cascade with an energy storage system was established, and the stability of the cascade system was analyzed by impedance ratio criterion.

Then, considering the working characteristics of different energy storage media of Hybrid Energy Storage System (HESS), Empirical Mode Decomposition (EMD) is used to obtain each intrinsic mode component within the allowable range of charging and discharging frequency, and the Hilbert transform is used to obtain the main frequency of the energy storage power signal, so as to determine the filtering time constant and assign the high-frequency fluctuation to the super capacitor. The low frequency fluctuation is borne by the battery. Finally, the effectiveness and accuracy of the method are verified by simulation.

The proposed method distributes the imbalance power among power generators in a weighted or prioritized way under the premise of preferential consumption of renewable energy and satisfying inequality constraints. The method not only meets all constraints in HDEED problem, but also improves convergence of the algorithm and the diversity of the Pareto solution set.
