The impact of knowing the distribution function of wind power forecasting error in the economic operation of a power system is studied in this paper. The papers proposes that the distribution of the wind power forecasting error of a specific tool can be easily derived if, for that model, an evaluation of its performance is made off-line comparing the forecasted values of the tool with the actual wind power values in the same horizon. The proposed methodology is applied to the autonomous power system of Crete. It is shown that the improvement of the performance of wind power forecasting tool has significant economic impact on the operation of autonomous power systems with increased wind power penetration. The obtained results for various levels of wind power production and load show that using only mean absolute percentage error (MAPE) leads to significant change in the estimation of the wind power to be shed to avoid technical limits violation, especially if the wind power forecasting tool presents underestimation of the actual production","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126739367","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}

Although this can take better advantage of the unit life, it may not be the most cost effective strategy considering the fact that aging units often have higher operation and maintenance costs, and undesirable reliability consequences. In order to allow financial retain/replace decisions to be made; this paper proposes a cost effectiveness analysis method. Each generation unit under evaluation is given an asset health index (AHI), which is defined as the ratio of the NPV of running a unit to end of life over the NPV of immediate replacement. AHI is a self-explanatory quantitative indicator of the cost effectiveness for unit replacement. In-house software named asset health index calculator (HI) has been developed and an AHI has been produced for every diesel generation unit in service in the BC Hydro non-integrated areas (NIA) for the future 20 years, so planners can easily foresee when and which units should be replaced in this planning window. A performance evaluation of the generation units is also required by not discussed in this paper. The development of the AHI and the performance evaluation allow proactive fleet capacity planning and justifiable asset management expenditure. As an effective planning tool, the proposed AHI method can be extended to the evaluation for other aging assets","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115993348","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}

Factors affecting investment vary from these times reduce in capital flows following the Asian crisis, to poor incentives for generation investment in market design. The difficulty, at least in Latin America, to operate energy-only markets without disruptive prince interventions or market power abuse, has made generation investment a challenge. Markets equipped with variations of capacity payments have performed better with concerns of inefficient investment and high final prices for consumers. The recognition that long-term contracting mechanisms and demand participation in handling supply risk are key to supply adequacy has lead to a new generation of market designs. The paper presents some of the challenges for financing generation in this new type of market designs from development banks perspective, and shows empirical evidence on what has been the investment practices in some selected countries in Latin America, spot market risk and also outside-of the energy market risk factors have play an important role, in order to diminish these risk investors often look for more comfortable traditional long-term contracts in opposition to newly market design paradigms which brings concerns on their effectiveness in developing countries if other institutional and regulatory factors are not in place","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116006474","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}

One of the main elements of a ferroresonance circuit is saturable inductance. Existing electromagnetic transient programs such as EMTP present various models of magnetization characteristics of saturable cores. However, to study ferroresonance phenomenon, many papers have used single-valued characteristics for magnetic cores and ignored hysteresis effects. In this paper, some modeling methods of magnetic core characteristics are reviewed and the results of a ferroresonance test on a 33 kV voltage transformer are presented. Using the results of the voltage transformer no-load test, the magnetization characteristic is obtained and the magnetic core is modeled by various methods. The comparison between the experimental and simulation results shows that in analysis of some ferroresonance cases, the aspect of inherent variation of inductance in hysteresis loops is more important than the power loss introduced by these loops. Therefore, in such cases, the core characteristic must be represented by a hysteretic model. Otherwise, the simulation results may present significant errors","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"819 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116420870","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}
