Adaptive Near-Optimal Compensation in Lossy Polyphase Power Systems

Adaptive Near-optimal Compensation in Polyphase Power Systems with Linear and Nonlinear Loads

Department of Electrical and Computer Engineering Doctor of Philosophy in Electrical Engineering by Ronald Didier Hernández G. We provide a formulation and adaptive solution for power flow optimization in polyphase power systems with significant source (line) impedance in the presence of either linear or nonlinear loads. The known optimal solution for this problem relies on (typically time-vari...

wind farm impact on generation adequacy in power systems

در سال های اخیر به دلیل افزایش دمای متوسط کره زمین، بشر به دنبال روش های جایگزین برای تامین توان الکتریکی مورد نیاز خود بوده و همچنین در اکثر نقاط جهان سوزاندن سوخت های فسیلی در نیروگاه های حرارتی به عنوان مهم ترین روش تولید توان الکتریکی مطرح بوده است. به دلیل توجه به مسایل زیست محیطی، استفاده از منابع انرژی تجدید پذیر در سال های اخیر شدت یافته است. نیروگاه های بادی به عنوان یک منبع تولید توان...

Optimal Parametric Backward-Adaptive Lossy Compression

We present a new generic mechanism for “on-line” construction of a vector quantizer codebook, based on blockwise backward-adaptive parametric encoding. The workings of the proposed scheme is explained by the principle of “natural type selection”: In the limit of large vector dimension, the type of the first distortion-matching codeword within a random codebook coincides with an iteration of the...

Near-Optimal Adaptive Polygonization

Consider a triangulation of the xy plane, and a general surface z = f(x; y). The points of the triangle, when lifted to the surface, form a linear spline approximation to the surface. We are interested in the error between the surface and the linear approximant. In fact, we are interested in building triangulations in the plane such that the induced linear approximant is near-optimal with respe...
