Whether the power system stabilizer (PSS) parameters set under the condition of large load can still effectively suppress low-frequency oscillation under the condition of “deep peak regulation” is the key to ensure the safe operation of power system in “deep peak regulation”. Firstly, the basic principles of low-frequency oscillation and the action of PSS are described based on the Philips-Heffron model, and the influence of active load variation on the uncompensated characteristics of the generator excitation system was theoretically analyzed. Then based on the establishment of RTDS generator model platform, the uncompensated characteristics of the generator excitation system under different active loads was calculated. Under the condition of using the same PSS parameters, the effects of single-machine and dual-machine model systems PSS on suppressing low-frequency oscillations were simulated and studied respectively. Finally, the simulation research results are verified by on-site real machine test.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114746353","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}

The control strategy of SCSR was divided into three layers, namely the inner layer, the outer layer and the outermost layer. It was a difficult problem to implement the strategy in the system debugging to verify whether the controllable high-resistance can act accurately under this strategy. This paper expounds the principle of the three-layer control strategy of SCSR, performs calculations under system debugging conditions, and obtains the verification method during system commissioning, and the debugging is successfully carried out. This article finally got that the verification method described can verify the three-layer control strategy, and the controllable high-resistance action is correct.

However, when the power system topology changes, the transient stability characteristics of the system will change greatly. At the same time, the accuracy of the existing transient stability assessment methods will be greatly reduced, which will affect the results of transient stability analysis. This paper uses graph neural network (GNN) to add topology information to the model, and realizes the combination of electrical information and grid topology information to construct a transient stability evaluation model. The information of the grid topology is added to the model to improve the adaptability to changes in the system topology. A simulation example verifies the feasibility of the model in transient stability assessment, and proves that the model has greater generalization capabilities when the power grid topology changes.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116258660","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}

Hence, traditional power system operation rules which are based on the experience of operators are difficult to be applied to large-scale modern power systems. The development of machine learning provides a new perspective for online formulation of operation rules. Transmission section determination is the basis in formulating operation rules, and in this paper, the Clustering by Fast Search and Find of Density Peak (CFSFDP) algorithm and a cut-vertex search method are adopted to identify key transmission sections of the power system concerned. Then, the Monte Carlo simulation method is used to generate massive training samples, and the Total Transfer Capability (TTC) is calculated for each key transmission section. After feature selection, the Radial Basis Function (RBF) neural network is used to train the model to attain the operation rules. Finally, the IEEE 39-bus power system is employed to demonstrate the proposed method.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123226336","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}
