When large-scale photovoltaic energy is connected to the power grid, it will pose a challenge to the security and stability of the power grid. To solve the problem that the prediction accuracy of current photovoltaic power time series is not high and there is no reference interval for the prediction results, a photovoltaic short-term power interval prediction model based on variational mode decomposition (VMD) and improved grasshopper algorithm (GOA) - Kernel Extreme Learning Machine (KELM) is presented. The prediction model first uses VMD algorithm to decompose the original data and get several subsequences with lower complexity; then uses grey correlation method to select the subsequences with higher degree of association with the original data and divide them into low-frequency, medium-frequency and high-frequency sequences; Then establishes a kernel limit learning machine prediction model optimized by grasshopper algorithm, and makes the subsequences with higher degree of association from the original sequence. The training of mid-frequency and high-frequency sequences obtains the set of prediction errors from the predicted and actual values and the model. Finally, the density curve of error function is calculated using the kernel density estimation method (KDE). Based on this curve, the prediction intervals with 85% and 90% confidence are established to realize the interval prediction of photovoltaic power.","PeriodicalId":316980,"journal":{"name":"2021 IEEE 4th International Conference on Electronics Technology (ICET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133314348","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}

To solve the problem of subsynchronous oscillation and ensure the safe and stable operation of steam turbine generator units and power system is a challenging topic in the world. The shafting of a type of turbine generator unit usually has $3sim 4$ natural torsional vibration frequencies. When the type of turbine generator unit increases in the system, the natural torsional vibration frequency also increases exponentially. Different natural torsional vibration frequencies have different coupling degrees with the electrical resonance of the series compensated output system, which leads to more complicated SSR. Taking the output system of series compensation after the expansion of Jinjie power plant as an example, the analysis and calculation are carried out, and the engineering application scheme of subsynchronous torsional vibration suppression of each unit shafting under multi model and multi-mode is proposed.","PeriodicalId":316980,"journal":{"name":"2021 IEEE 4th International Conference on Electronics Technology (ICET)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114421619","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}
