La Electricidad de Caracas, an AES electrical utility in Caracas, Venezuela. Power system operations are subject to growing restrictions and, therefore, have had to become more efficient to enhance the cost structure and comply with regulatory demands on quality of service. Now, technical studies and decision-making processes are not only based on \"traditional\" technical criteria, but also use other methods, such as asset management, work management and strategic planning. In addition, customers are increasingly taken into account in these processes. The article presents examples of methods such as reactive power sources optimization, short circuit levels studies, network investment projects, budget managing, and low frequency load shedding and area separation","PeriodicalId":406067,"journal":{"name":"2006 IEEE/PES Transmission & Distribution Conference and Exposition: Latin America","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115608683","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}

An ant colony search (ACS) and a hybrid ACS combining membership functions are proposed to achieve both the global optimization and the fastest computing time.

We know that power factor correction capacitors are sensitive to harmonics and one factor of the failures of power capacitors indicates the prime odd harmonics like 5th, 7th, 11th, 13th harmonics.
