As these DERs are joining the existing conventional power systems, they must follow the existing grid control. However, standard communication between utilities and consumers who own these DERs is needed for the grid control of state variables and for the exchange of power as well. Therefore, a general strategy is proposed depending on the UCTE grid control and international communication standards, such as IEC 61850, IEC 60870-5-104 and IEEE P1815. Hence, photovoltaic systems connected with batteries are proposed in order to simulate two grids. Then, logical nodes needed for primary and secondary grid control are adopted from the IEC 61850, which ensures interoperability. For communication, the standard legacy SCADA protocols IEC 60870-5-104 and IEEE P1815 are proposed, which introduce standard communication mechanism.","PeriodicalId":424662,"journal":{"name":"2011 16th International Conference on Intelligent System Applications to Power Systems","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134444110","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 fluctuations inherent in renewable energy resources imply the need to also integrate the demand side actively into the control of the power system. For this effort to succeed, a new control infrastructure has to be put into place. The power system is a distributed system, and it needs a sophisticated communication framework to cope with communication problems, such as delays and failures. Recently, behaviour descriptions have been proposed as an alternative to synchronous communication in power systems, especially with small distributed energy resources. This article presents an implementation of behaviour descriptions and an experiment that has been carried out to evaluate the feasibility of such an approach.","PeriodicalId":424662,"journal":{"name":"2011 16th International Conference on Intelligent System Applications to Power Systems","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131785890","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}

Specifically, we modeled switches in the power distribution systems as intelligent agents who can communicate and coordinate together to find a global optimal solution to the power distribution service restoration problems. We modeled the society of intelligent switch agents as local power committees in a distribution system and propose a coordination method for the distributed local power committees so that they could reach a consensus among many proposed service restoration solutions after faults are detected in the distribution feeders. We show how the local switch agent committees find the global optimal restoration solution to all local power demand issues through communicating and propagating the power demand issues, proposing local candidate solutions and combine issues and solutions and finally finding solution by constraint satisfaction. We also compare our multiagent approach to the traditional methods and benchmark problems from power restoration research literatures and show satisfactory performance results.","PeriodicalId":424662,"journal":{"name":"2011 16th International Conference on Intelligent System Applications to Power Systems","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132191706","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}

For a large power system, the loadability surface is a complicated hyper-surface in parameter space, and local approximations are a necessity for any analysis. Unfortunately, inequality constraints due to for example generator overexitation limiters, and higher codimension bifurcations, makes the loadability surface non-smooth. In this paper we intend to deeper investigate under which conditions the power system loadability boundary will have no visible corner at an intersection of a saddle-node bifurcation part and a switching loadability limit part of the boundary. We propose that such points are called Tangential Intersection Points.","PeriodicalId":424662,"journal":{"name":"2011 16th International Conference on Intelligent System Applications to Power Systems","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115479615","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}

We initially present a method for symbolically defining and integrating complex nonlinear dynamical systems in order to automatically compute the model of the devices that are connected to the power system, independently of their complexity. This generic form of the device model as computed by the “symbolic integrator” is then used as an input to numerous advanced real time power system applications. In this paper, an autonomous state estimator is presented as a demonstrative application. The proposed operational scheme is based on the combination of advanced state estimation algorithms that enable robotic (autonomous) power system operation. A laboratory setup is also presented to demonstrate the applicability of the proposed scheme.","PeriodicalId":424662,"journal":{"name":"2011 16th International Conference on Intelligent System Applications to Power Systems","volume":"311 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124417626","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}
