Treated as additional control variables, two strategic parameters called the mutation factor (F) and the crossover constant (CR) are dynamically self-adaptive throughout the evolutionary process. Since tuning of the parameters is a tedious task due to complex relationship among parameters, the optimal parameter settings may never be found, and possibly leads to a local optimal solution. An augmented lagrange multiplier method (ALM) is applied to handle equality/inequality constraints. To demonstrate the effectiveness of the proposed algorithm, two ELD problems considering: (1) multiple fuels, and (2) multiple fuels with valve-point effects, are tested and compared with other methods e.g. differential evolution (DE) based methods, modified particle swarm optimization (MPSO), improved genetic algorithm with multiplier updating (IGA_MU) etc. The results show that the proposed SADE_ALM is very effective and provides promising capability for solving the economic load dispatch problem with piecewise quadratic cost function.","PeriodicalId":181574,"journal":{"name":"2006 International Conference on Power System Technology","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128732590","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 accurate identification of the faulty feeder becomes a difficult task due to many disadvantageous factors. The conventional scheme is implemented with the comparison of the magnitude, polarity or the phase angle among the zero-sequence currents. Therefore, it is hard to be implemented into the feeder protection equipped on the FTU. A novel zero-sequence over-voltage protection scheme based on zero-sequence current compensation is therefore proposed. The fundamental method is based on the measurement of the zero-sequence over-voltage, and the tripping time characteristic adopts the inverse time delay. By virtue of the analysis of distribution of the zero-sequence transient current, a transient RMS value of the zero-sequence current is utilized to form the composite compensation voltage together with zero-sequence voltage. This voltage is utilized to revise the inverse time-delay curve to achieve the selectivity of the protection. The principle is verified with the EMTP simulator.","PeriodicalId":181574,"journal":{"name":"2006 International Conference on Power System Technology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130677791","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}
