PMU measurement quality is the key issue in application purposes. To evaluate the measurement quality, the concepts of total vector error (TVE) and benchmark tests, including the magnitude, phase and frequency step tests, are proposed in the C37.118 standard. It also includes requirements for test results. This paper reports the results of tests performed on several PMUs. These tests include both steady state and dynamic conditions conforming to the new requirements under development by the IEEE for the updated C37.118 standard. In addition to validating the new IEEE requirements with actual PMU measurements, the results evaluated by TVE are discussed and with errors analyzed based on phasor magnitude and angle.","PeriodicalId":206094,"journal":{"name":"2010 5th International Conference on Critical Infrastructure (CRIS)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115724231","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 most serious conflict influencing wind power development is that the currently adopted price of wind power on-grid does not take this fluctuation or the impact on the system operation into account. Currently, quotas and enforcing access is broadly used in wind power regulation. It is now required that all wind power output should be accepted by the grid, and is rewarded with a guided rate. But with the increase of wind power penetration to power grid, a more effective price regulation to wind power should be set up with wind output uncertainty into account. This paper takes wind farms in different areas in China as the research objects and uses accounting cost analysis approach to calculate wind power costs, which enables the wind farms in different areas to get the same rate of return on investment as that of thermal power plants. These tariffs will be derived as a basic price for the reference by the power grid then. The basic wind power prices are multiplied by a penalty factor which is an innovative as the final prices paid to the wind farms. The penalty factor is related to the accuracy of wind power output. If the accuracy of the wind farm output is higher than that of the regional average one, the penalty factor will be greater than one, so that the really paid wind power price is higher than the base value and the income of the wind farm will be increased, otherwise the earnings will be reduced. To illustrate the problem, an example is given. The use of this penalty factor will eventually help stimulate wind farms to improve the accuracy of wind power output, and improve the stable operation of the systems with large wind power penetration, and promote the sustainable development of wind farms.","PeriodicalId":206094,"journal":{"name":"2010 5th International Conference on Critical Infrastructure (CRIS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116544746","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 wireless communication network of the energy meters is derived from a cellular automation framework where each meter is modeled as an agent. An adversary objective of attack tree based on the device vulnerabilities is enumerated with the possible vulnerabilities of energy metering devices and communication framework. The cyber threats considered in this preliminary analysis is worm propagation. Transmission of a legitimate firmware update is then followed with simulation and analysis based on anomaly patterns, i.e., the traffic statistics of the malicious activities within the network. The mean absolute percentage error (MAPE) is employed to measure the variation of network trend based on historical patterns, where a new anomaly pattern can be determined based on erroneous discrepancies. A simulation model based on an example Singapore housing block has been made to demonstrate the impact of worm propagation and feasibility.","PeriodicalId":206094,"journal":{"name":"2010 5th International Conference on Critical Infrastructure (CRIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129318323","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}

This paper presents different connection methods on different operation conditions based on one actual power supply system. If active power in isolated system is larger than load demand, cutting-generator is adopted; if less, low-frequency load shedding is adopted to keep system stable firstly, then synchronous connection conditions are checked to connect isolated system with external power system in steady state. This connection method is safe and reliable. When there are fewer generators in isolated supply system, stability can't be remained by load shedding, it is necessary to rapidly connect with external power grid in order to remain power supply stable, this time grid connection must be conducted in transient state. In this situation connection conditions are decided mainly by phase and frequency difference. This rapid connection method is analyzed and verified, and connection conditions are derived by calculation.","PeriodicalId":206094,"journal":{"name":"2010 5th International Conference on Critical Infrastructure (CRIS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123875439","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}

In order to obtain higher accuracy, a new method—genetic algorithm neural network based on rough set theory is proposed in the paper. Considering many factors that influence wind speed forecasting, reduction algorithm of rough set theory is introduced to choose the neural network's input parameters. Parameters which have higher correlation with forecasting are used as input to reduce the work and calculation time of neural network. And the genetic algorithm with global searching capability is used to optimize the initial weights of the neural network to overcome slow convergence speed and easy to fall into the local minimum of BP algorithm. The forecasting values agree well with the data which measured in a wind farm. The calculation examples show that the new method can improve the speed and the accuracy of prediction, which prove the feasibility and validity of the new method in the wind speed forecasting.","PeriodicalId":206094,"journal":{"name":"2010 5th International Conference on Critical Infrastructure (CRIS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126263045","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}

An aspect of these systems, which is less well researched, is the WAMC system dependence on high performance communication. This paper presents results of research on the use of Internet Protocol (IP) networks for both PMU and Remote Terminal Unit (RTU)/Intelligent Electronic Devices (IED) data for monitoring purposes. The paper examines performance aspects of the IP network Infrastructures when utilized by both: continuous PMU data streams and critical IED/RTU data.
