Along with random errors the measurements of EPS state variables contain quite often bad data. The paper addresses the algorithms of bad data detection by the test equation method at decomposition of a state estimation problem. The authors outline the concept of test equations. The decomposition algorithm includes structural and functional decomposition of the state estimation problem. The structural decomposition is carried out by dividing the calculated scheme into subsystems with respect to voltage levels. The functional decomposition is performed in accordance with the problems solved during the state estimation process: bad data detection, state estimation on the basis of the quadratic and robust criteria. The authors present the methods for detecting bad data a priori and solving the state estimation problem on the basis of robust criterion using test equations. Consideration is given to the applicability of genetic algorithms to these problems. The experimental studies have confirmed the efficiency of the suggested approaches.","PeriodicalId":410611,"journal":{"name":"2014 IEEE International Energy Conference (ENERGYCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133974111","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 that context, new methodologies are needed in order to identify and to accurately quantify the impact of this massive renewable penetration on the grid operation. For this purpose, the authors of this study have developed in a previous analysis a probabilistic load flow tool directly based on the use of smart meters data. The goal of this tool was to quantify probabilities of overvoltage in radial low voltage grids with increased photovoltaic penetrations. However, the drawback of this approach was the too long (15 minutes) sampling time step of smart meters that did not allow the consideration of fast fluctuations of photovoltaic generation. In the present paper, an original adaptation of the existing tool is therefore presented, which enables the consideration of short temporary photovoltaic power fluctuations. Thanks to this new development, it is shown that a more accurate estimation of overvoltage situations, due to photovoltaic generation, is permitted.","PeriodicalId":410611,"journal":{"name":"2014 IEEE International Energy Conference (ENERGYCON)","volume":"210 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132929531","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 increasing number of thermoelectric elements, such as heat pumps and thermal storage, will enable conversion from heat to electricity and vice versa. Control in this environment therefore requires an integral management of both the heat network and the electricity network. In this paper we present a simulation framework which is able to simulate and coordinate multi-commodity flows on a district level using a wide variety of appliance models, taking into account different types of business objectives (e.g. time of use tariffs, peak shaving, etc.). To manage these flows a market-based multi-commodity algorithm, for integrated coordination of electricity and heat flows, was developed and integrated in the simulation framework. The algorithm is an enhancement of the PowerMatcher concept and thus inherits its advantages such as scalability and user autonomy. An example is given to demonstrate the use of both the simulation framework and integrated control algorithm.","PeriodicalId":410611,"journal":{"name":"2014 IEEE International Energy Conference (ENERGYCON)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123611517","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}

Comparison of all the relevant characteristics of the considered technology is of great significance for power system designers or operators. However, the differences between characteristics and dimensions of variables in optimization procedure models lead to the fact that classical algorithms become computationally inefficient and more difficult to implement. In this paper a procedure that is based on a heuristic optimization method and Pareto optimality is proposed. The procedure enables comparison of all considered scenarios in the entire space of control variables, while their parallel processing ensures timely elimination of scenarios that do not provide a better solution for any criteria than the other scenarios. The proposed procedure is illustrated on the example of selecting type, size and location of FACTS devices in the IEEE 57 bus test system. The optimization results, with different number of objective functions, illustrate the effectiveness of the procedure and point out the possibility of application in solving optimization problems of realistic power systems.","PeriodicalId":410611,"journal":{"name":"2014 IEEE International Energy Conference (ENERGYCON)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127666700","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}
