Battery energy storage system (BESS) is considered as one of solutions to this problem. In operation of the BESSs, their characteristics should be taken into consideration. For example, to extend the life time of the BESS, its state of charge (SOC) should not reach the upper or lower limit. In addition, efficiency of the BESS inverter is degraded when its output is low. In this paper, when multiple sets of BESSs and different kinds of BESSs are installed into a power grid, a new control method of the BESSs for load frequency control taking into account their characteristics is proposed. Numerical simulations for the multi-machine power system model are carried out to show effectiveness of the proposed control method. It is made clear that their total inverter loss can be reduced and all of their SOC can be always kept within the limits while contributing to the frequency control by the proposed method.","PeriodicalId":155801,"journal":{"name":"2014 Power Systems Computation Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126990034","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}

Renewable energy sources have to be installed on a large scale causing a more complex operation of the power distribution grids due its stochastic behavior. Advanced automation and information technology approaches, concepts and algorithms are being applied to operate such complex systems. Interoperability and standardized interfaces are important topics which have to be considered realizing a Smart Grid. A standard-compliant formal approach for the modeling of power utility automation and control applications is missing up to now. This paper therefore introduces a novel approach using the well-known model-driven engineering concept from computer science for the development of Smart Grid automation applications. This method focuses on the usage of the power utility interoperability approach IEC 61850 and the distributed automation reference model IEC 61499 as basis for the proposed modeling concept. An overview of the engineering method, corresponding transformation rules as well as an explanatory example are provided.","PeriodicalId":155801,"journal":{"name":"2014 Power Systems Computation Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126114220","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 availability of domestic refrigerator and industrial bitumen tank load to provide frequency response services was investigated. The time of a day that the load is available to provide frequency response without interfering with its inherent function was measured through field investigations by Open Energi. Based on the measured periods of availability, the number of frequency responsive loads to be aggregated for frequency response over a day was estimated. Decentralised dynamic controllers were then developed which enable loads to vary their power consumption in proportion to the variation of grid frequency. The availability of the dynamically controlled refrigerator and bitumen tank load for frequency response was modelled. Variation of the availability during a severe frequency incident was simulated. The results showed that the aggregated loads were able to provide dynamic response to grid frequency continuously and repetitively over a day.","PeriodicalId":155801,"journal":{"name":"2014 Power Systems Computation Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121484044","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}

Network expansion comprises several alternatives for feeders and transformers. Analogously, the installation of distributed generation takes into account several alternatives for conventional and wind generators. Unlike what is customarily done, a set of candidate nodes for generator installation is considered. Thus, the optimal expansion plan identifies the best alternative, location, and installation time for the candidate assets. The model is driven by the minimization of the net present value of the total cost including the costs related to investment, maintenance, production, losses, and unserved energy. The costs of energy losses are modeled by a piecewise linear approximation. As another distinctive feature, radiality conditions are specifically tailored to accommodate the presence of distributed generation in order to avoid the isolation of distributed generators and the issues associated with transfer nodes. The resulting optimization problem is a mixed-integer linear program for which finite convergence to optimality is guaranteed and efficient off-the-shelf software is available. Numerical results illustrate the effective performance of the proposed approach.","PeriodicalId":155801,"journal":{"name":"2014 Power Systems Computation Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129070430","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}
