Here, Artificial Bees Colony (ABC) is an optimization tool, which is used in two phases, the employee bee and the onlooker bee to optimize the bidding parameters. From the optimized parameters the exact solution is predicted by the Cuckoo Search (CS) algorithm, which is replaced by the scout bee phase of the ABC. In the CS algorithm prediction function is based on the levy flight search. It is used to discover the exact parameters from more complicated problems with the use of probability. This action makes the ABC as an adaptive technique. The required demand of every period is identified by the learning and testing algorithm Neural Network (NN). Then the proposed adaptive technique maximizes the profit levels and meets the demand at minimum pricing levels. Finally the proposed method is implemented in the MATLAB/simulink platform and effectiveness is analyzed by using the comparison of different techniques like ABC, PSO, ABC_PSO. The comparison results are demonstrating the superiority of the proposed approach and confirm its potential to solve the problem.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129108370","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}

In this paper an attempt has been made to generate biodiesel from soybean oil using transesterification and three step method. The kinetics of transesterification reaction heterogeneously catalyzed by calcium oxide was studied in order to understand the reaction mechanism of the system. The three step method comprises with saponification of oil, acidification of the soap and finally esterification of free fatty acid (FFA). Both the techniques go through a number of parameters like reaction conditions, catalyst selection, reaction time, temperature and molar ratio of oil to intermediate products and additives required to be optimized. The results showed that transesterification reaction obeyed pseudo first-order kinetics with a reaction rate constant k=0.023 min.-1 for 5 wt.% CaO and yield obtained ~95% within 120 min with a viscosity of 4.10 mm2/s. In the three step method, conversion of biodiesel was found ~98% with molar ratio of methanol to FFA 5:1. Conversion of soybean oil into its subsequent biodiesel was verified and the results are comparable to commercial diesel. Consequently, biodiesel from this potential source can be a suitable pathway to commit our present and future fuel demand in the world.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115800373","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}

Hence, it becomes more and more vital to be able to perform power system studies, including wind farm behavior, and it demands modeling of wind farms. This paper deals with the implementation of FACTS controller called static synchronous compensator STATCOM to improve the performance of the grid connected wind farms. The essential feature of the STATCOM is that it has the ability to absorb or inject fastly the reactive power with power grid. Therefore the voltage regulation of the power grid with STATCOM FACTS device is achieved. Moreover restoring the system stability after severe disturbance is achieved by using the STATCOM. to validate the usage of STATCOM a simulated model is designed when subjected to sudden load variation. The results prove the effectiveness of the controller in restoring the system stability.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122445156","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}
