Finally, this paper compares the above model to the traditional k-means and DBSCAN model using data from the grid.

Therefore, this paper proposed a novel optimized Gauss integral for transmission line voltage measurement, which combines the Gauss integral method and genetic algorithm. Furthermore, position sensitivity constraint condition is taken into the genetic algorithm. It is found that the optimized Gauss integral method improves the calculation accuracy greatly and makes the sensor distribution more reasonable for single conductors and double loop conductors, and for the catenary line, the optimized Gauss integral method used below the highest point of the catenary line is the only useful method.","PeriodicalId":413409,"journal":{"name":"2022 IEEE 6th Conference on Energy Internet and Energy System Integration (EI2)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126860009","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}

Therefore, a collaborative emergency control strategy making use of DC power support is presented to guarantee transient stability after HVDC-link blocking. Firstly, the control enabling criterion is defined based on the variation characteristics of the phase trajectory slope during the first swing, while the analytical equation between the needed control quantity and the system parameters is derived. Secondly, the mathematical relation between the provided control quantity and the number of HVDC-links participating in the power support is deduced, and the participation sequence is determined on the basis of the post-fault stable equilibrium points. Additionally, the time delay of the whole implementation is considered.

Firstly, the relationship between the frequency response characteristics of the power grid and the total inertia of the system and the relationship between the frequency distribution characteristics of the multi-machine system and the inertia distribution are analyzed. Aiming at the frequency safety constraints of the power grid, an estimation method for the minimum inertia demand of the system is proposed. Considering the frequency distribution characteristics of the power grid and the distribution of load, new energy and direct current, the distribution scheme of inertia among different regions in the synchronous power grid is proposed to guide the arrangement of the power-on and output of the synchronous units in the system. The simulation analysis based on the actual large power grid in East China power grid shows that for the power system with large amount of new energy generation and DC feed, the method can effectively reduce the maximum deviation of frequency and the difference of time-space distribution, which verifies the effectiveness of the proposed method.","PeriodicalId":413409,"journal":{"name":"2022 IEEE 6th Conference on Energy Internet and Energy System Integration (EI2)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121137989","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}

Due to the covert characteristics of false data injection, the existing detection methods can be deceived and lead to power system overload. To solve this problem, an adaptive defense method based on the linear-quadratic form (LQR) is proposed. Considering the impact of attack on the physical system, a physical dynamic model of the power grid is constructed. Taking the covert characteristics of false data injection attack into account, the adaptive LQR controller-based defense method is developed. Through the design of parameters of LQR, the proposed controller can respond quickly to deceptive attacks.
