The expected unsupplied energy in a given time interval divided by the annual peak load is used as the reliability index. In calculating this index, the forecast hourly loads, sales and purchases, the changes in the operating schedule and unit operating modes, and the capacity and energy constraints on hydraulic generation are considered. Applications in generation schedule reliability assessment, economy sales assessment, mid-term reserve planning, and maintenance scheduling are presented.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129392182","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 need to follow rapid power variation from uncontrolled wind farms with expensive gas turbines limits the amount of penetration of wind energy systems in existing utilities. An AC/DC/AC interface makes it possible to limit the power variations from the wind farm. An optimal level to which the wind output should be limited is found in terms of the distribution of wind power output and the relative cost of the fast acting and base loaded units. Using the optimal cutting point for the wind output each wind farm can be included in the economic dispatch calculation. The economic advantage of limiting wind power output is demonstrated on an example system. Using a hypothetical system it is shown that wind penetrations as high as 16.75% may be economical using the optimal strategy made possible by the AC/DC/AC interface.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128034724","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 most valuable and effective tool in the control room, however, is an experienced operator. This paper presents a method by which the deductive and inductive decisions which an operator makes in assessing system security are emulated on a computer. This emulator learns about the system every time a contingency analysis or load flow is performed, and makes a security assessment every time a state estimator is run. This type of program would make the equivalent of an experienced operator available to the actual operator at any time. This would be useful to inexperienced operators or when the system was in a rarely seen configuration.","PeriodicalId":227345,"journal":{"name":"IEEE Transactions on Power Apparatus and Systems","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114682261","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}
