The new technique converts all objective functions to a single objective function by deriving a single aggregate objective function using specified or selected weighting factors. Since the optimal PID controller parameters are dependent on the selected weighting factors, the weighting factors was also treated as dynamic optimizing parameters within the Particle Swarm Optimization as a dual optimization and global selection of PID controller optimal parameters as well as best set of weighting factors. Computer simulations and experimental results show that the performance of the optimal PID controller is better than that of the traditional PID controller.","PeriodicalId":246039,"journal":{"name":"2009 International Conference on Power Engineering, Energy and Electrical Drives","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134420353","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 main advantage of such SoC based systems is cost and space effectiveness. Such systems are available for very cheap cost, which can be further used for some practical purposes with little effort, hence very practical solution for the applications such as protective relays. In this paper a “Universal” Motor Protection relay is proposed utilizing Soc based design approach. Furthermore, a digital low-pass FIR filter has also been implemented on the same chip, which overcomes the requirement of external filtering. The Xilinx-Spartan FPGA is used to implement the relay which takes three phase currents as input and provides a number of protections for the motor like over-current, under-frequency, over-frequency, thermal protection and negative phase sequence, etc. It has been shown that not only the hardware requirement is optimized but also the response time is improved with respect to the existing prototypes.","PeriodicalId":246039,"journal":{"name":"2009 International Conference on Power Engineering, Energy and Electrical Drives","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131008822","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}

According to Iran power market characteristics, in which participants should declare their maximum available energy to the ISO, Bertrand model is adopted for strategic bidding in the power market. Then, by transforming incomplete data that each GENCO has from others, into complete information using Bayesian Nash equilibrium, a proper method are proposed considering the power market characteristics, for maximization of GENCOs' profit according to the other GENCOs' bidding behaviors and power system operating conditions. Because of uncertainty of sources in a power system such as strategic behavior of opponent GENCOs, demand fluctuations and forced outage of network components, calculation of equilibrium point is not enough in proper strategic bidding, so the problem utilized so that risk factor is taken into account. The method is tested on a partial system, including five GENCOs, and the numerical results showed in detail the efficiency of the modeling and the proposed method of bidding behavior for generation companies.","PeriodicalId":246039,"journal":{"name":"2009 International Conference on Power Engineering, Energy and Electrical Drives","volume":"8 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114052331","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}

There are several mathematical models that are usually used for calculation of short-circuit currents in DC auxiliary system. In this paper, the authors performed short-circuit currents calculation for one real DC auxiliary system of power plant using three different, well-known, mathematical models.

The secure and reliable operation of the power system implies the need for scheduling in advance the energy sources that will produce, so that the power system is balanced. Therefore, the use and importance of the wind power is strictly dependent on the ability to predict the wind in advance. In this paper, ARMA models are used to forecast the wind speed in terms of a medium-term prediction. Furthermore, an investigation on the benefits of pre-filtering the wind speed time series using wavelets is carried out. Some simulations are done with the twofold purpose of evaluating the performance of ARMA models as compared with reference models and investigating whether the wavelet pre-filtering technique leads to an improvement of the forecast results.","PeriodicalId":246039,"journal":{"name":"2009 International Conference on Power Engineering, Energy and Electrical Drives","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133788264","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}

Based on a simulation model in ADVISOR, one can evaluate the performances, the emissions and then the Ecoscore and the User Satisfaction for different driving scenarios. To establish a rationale methodology for assessing the eco-efficiency character, we adopt a multidisciplinary optimization approach while minimizing / maximizing both Eco-score and User satisfaction objective functions. The proposed approach is then used to establish a comparison between HEV (hybrid electric vehicle) and HHV (hybrid hydraulic vehicle) configuration by highlighting the effect of different energy storage systems (batteries, ultra capacitors, hydraulic system), mechanical and electric components sizes upon the optimized HEV design. The selected application is the comparison of different mild parallel hybrid buses. Results show that the hybrid electric buses using ultra capacitors have almost the same performances as those using batteries, while the HHV technology can compete with HEV because of the hydraulic components low cost and recyclability if possibly using of water as motor/pump fluid.","PeriodicalId":246039,"journal":{"name":"2009 International Conference on Power Engineering, Energy and Electrical Drives","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126952523","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}
