To deal with the inability, a recent work proposes to utilize the unused historical data for power system state estimation. Although able to achieve much higher accuracy, the new approach is slow due to the burden by sequential similarity check over large volumes of high dimensional historical measurements, making it unsuitable for online services. This calls for a general approach to preprocess the historical data. In this paper, we propose to achieve such a goal with three steps. First, because the power systems are with periodic patterns, which create clustered measurement data, dimension reduction is proposed to remove redundancy, but still able to retrieve similar measurements. To further reduce the computational time, the k-dimensional tree indexing approach is employed in step two to group the clustered power system data into a tree structure, resulting in a log-reduction over searching time. Finally, we verify the obtained historical power system states via AC power system model and the current measurements to filter out bad historical data. Simulation results show that the new method can dramatically reduce the necessary computational time for online data-driven state estimation, while producing a highly accurate state estimate.","PeriodicalId":149134,"journal":{"name":"2014 IEEE PES General Meeting | Conference & Exposition","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125841255","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}

NERC standards CIP provides guidance on the identification and protection of critical cyber assets that support the reliability of power systems. Those assets don't include properties that are critical to the efficiency of electricity markets. However, attacking such properties may cost electricity market customers millions of dollars. This systematic approach fills the gap, and identifies the assets that have significant impacts on the market efficiency. The methodology is to analyze congested flowgates in an electricity market. It starts from a full list of the congested flowgates, and rank the congested flowgates with Estimated Potential Benefit (EPB) calculation. Top congested flowgates are then obtained. Apply correlation calculation to the top congested flowgates. A final list of critical congested flowgates is generates as a result. The simulation is performed on an ISO market. It identifies a short list of critical congested flowgates in the ISO market. Attacking one of those critical congested flowgates may cost the ISO market averagely thousands of dollars per hour. Future study is to develop security mechanisms for the critical congested flowgates. It includes both cyber security measures and physical security measures.","PeriodicalId":149134,"journal":{"name":"2014 IEEE PES General Meeting | Conference & Exposition","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133919207","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}
