This criterion is adopted independently of the economic impact (deficit cost) of the energy rationing. This paper proposes new expansion planning procedures for hydro dominated systems. The proposed methodology incorporates aspects related to costs of the deficit and the energy not supplied associated to energetic and electric reliability, respectively. The methodology is illustrated considering a configuration of the Brazilian interconnected system for 2004.

Is there a metric that can tell how far is a given power system state from its stability limit? But then, what is a stability limit? How to quantitatively describe such limit, or perhaps, limits, if more than one, and how to quickly determine how far is the transmission network from a state where a blackout might occur? The concept of steady-state stability reserve, introduced half a century ago to quantify the distance to instability, is also reviewed. Space and presentation time do not allow a detailed analysis, but an extensive list of references is provided to help promote further research. The main theme of this paper is particularly relevant in the aftermath of the wave of blackouts that affected utilities in US, UK and mainland Europe in 2003. The approach presented herein can help system dispatchers and reliability engineers foresee whether the transmission loading progresses, or is projected to progress, beyond the operating reliability limit.","PeriodicalId":308184,"journal":{"name":"IEEE PES Power Systems Conference and Exposition, 2004.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121736140","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 proposed PSO method is demonstrated and compared with linear programming (LP) approach and genetic algorithm (GA) approach on the standard IEEE 30-bus system.

In the case of the dual approach, a parametric autoregressive model of superior order is also considered.

The integration of DER into the power system control framework is part of the evolutionary advances that allow these resources to actively participate in the energy balance equation. Price can provide a powerful signal for independent decision-making in distributed control strategies. To study the impact of price responsive DER on the electric power system requires generation and load models that can capture the dynamic coupling between the energy market and the physical operation of the power system in appropriate time frames. This paper presents modeling approaches for simulating electricity market price responsive DER, and introduces a statistical mechanics approach to modeling the aggregated response of a transformed electric system of pervasive, transacting DER.","PeriodicalId":308184,"journal":{"name":"IEEE PES Power Systems Conference and Exposition, 2004.","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127804086","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 communication standard IEC 61850 permits interoperability without the use of gateways. Through the split of application and communication stack and through the standardized permitted extension of the supporting functions, the long-term validity of the standard is guaranteed. This approach leads to lower investment outlay, less training effort and lower life-cycle costs of substation automation systems. All automation functions as well as the single-line diagram of a substation are described by means of the substation configuration description language. Many migration paths are possible to allow a substation to be gradually IEC 61850-compliant. Existing equipment may be upgraded directly. Existing equipment may also be left intact, and an interface is established between this and any new IEC 61850-compliant equipment which is introduced when the substation is extended.","PeriodicalId":308184,"journal":{"name":"IEEE PES Power Systems Conference and Exposition, 2004.","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115819354","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}
