[ 1 ] - طراحی بهینه ترانسفورماتور به کمک الگوریتم ژنتیک
انتقال انرژی الکتریکی در مسافتهای طولانی به همراه لزوم کاهش تلفات و افت ولتاژ شبکه باعث استفاده از ترانسفورماتور در شبکه در سطوح ولتاژی مختلف آن می شود . نقش این عنصر در شبکه بهمراه قیمت بالای آن که به سبب استفاده از مواد گرانقیمت در ساخت آن ناشی می شود، لزوم طراحی بهینه آن را آشکارتر می سازد. در این مقاله با کمک گیری از مفهوم روش مدرن بهینه سازی بر مبنای آلگوریتم ژنتیک، روشی متفاوت با روشهای ب...
[ 2 ] - Hydrothermal Optimal Power Flow Using Continuation Method
The problem of optimal economic operation of hydrothermal electric power systems is solved using powerful continuation method. While in conventional approach, fixed generation voltages are used to avoid convergence problems, in the proposed algorithm, they are treated as variables so that better solutions can be obtained. The algorithm is tested for a typical 5-bus and 17-bus New Zealand networ...
[ 3 ] - Some Issues in Implementation of a Voltage Stability Analysis Function in an Energy Management System Environment
Over the last few years, the problem of voltage stability has received a lot of attraction from the power system community. This type of stability is now a major concern for utilities in both planning and operating conditions. Both static and dynamic aspects of the problem have been discussed and investigated by the researchers. The present paper concentrates on a Voltage Stability Analysis fun...
[ 4 ] - Basic Issues in Identification Scheme of a Self-Tuning Power System Stabilizer
Power system stabilizers have been widely used and successfully implemented for the improvement of power system damping. However, a fixed parameter power system stabilizer tends to be sensitive to variations in generator dynamics so that, for operating conditions away from those used for design, the effectiveness of the stabilizer can be greatly impaired. With the advent of microprocessor techn...
[ 5 ] - Optimum Proposal of Various Financial Rights in Secondary Short-Period Auction Market of Transmission Rights for Congestion Risk Management
Congestion Risk Management is one of the most important subjects of Transmission management in deregulated power system and world electricity market, especially markets of zonal or local pricing in which Firm Transmission Rights (in other words Financial Transmission Rights) are the main elements. In this study, considering subjects of Financial Rights of Transmission Congestion, methods of opt...
