TL;DR: In this paper, a microcomputer-based control of a residential photovoltaic power conditioning system is described, which is responsible for array current feedback control, maximum power tracking control, array safe zone steering control, phase-locked reference wave synthesis, sequencing control, and some diagnostics.
Abstract: Microcomputer-based control of a residential photovoltaic power conditioning system is described. The microcomputer is responsible for array current feedback control, maximum power tracking control, array safe zone steering control, phase-locked reference wave synthesis, sequencing control, and some diagnostics. The control functions are implemented using Intel 8751 single-chip microcomputer-based hardware and software. The controller has been tested in the laboratory with the prototype power conditioner and shows excellent performance.

07 Aug 1998TL;DR: In this article, a variable speed system for wind turbines is described, which consists of a wound rotor induction generator, a torque controller and a proportional, integral derivative (PID) pitch controller.
Abstract: A variable speed system for use in systems, such as, for example, wind turbines, is described. The system comprises a wound rotor induction generator, a torque controller and a proportional, integral derivative (PID) pitch controller. The torque controller controls generator torque using field oriented control, and the PID controller performs pitch regulation based on generator rotor speed.

TL;DR: An in-depth analysis of ice formation dynamics upon water droplet impact on surfaces with different wettabilities is presented, finding that ice nucleation delay on superhydrophobic surfaces is more prominent at moderate degrees of supercooling, while closer to the homogeneous nucleation temperature, bulk and air-water interface nucleation effects become equally important.
Abstract: Prevention of ice accretion and adhesion on surfaces is relevant to many applications, leading to improved operation safety, increased energy efficiency, and cost reduction. Development of passive nonicing coatings is highly desirable, since current antiicing strategies are energy and cost intensive. Superhydrophobicity has been proposed as a lead passive nonicing strategy, yet the exact mechanism of delayed icing on these surfaces is not clearly understood. In this work, we present an in-depth analysis of ice formation dynamics upon water droplet impact on surfaces with different wettabilities. We experimentally demonstrate that ice nucleation under low-humidity conditions can be delayed through control of surface chemistry and texture. Combining infrared (IR) thermometry and high-speed photography, we observe that the reduction of water–surface contact area on superhydrophobic surfaces plays a dual role in delaying nucleation: first by reducing heat transfer and second by reducing the probability of het...

TL;DR: In this article, the theory of loss-of-load probability mathematics has been generalized so that the effective load carrying capability of a new generating unit may be estimated using only graphical aids.
Abstract: The theory of loss-of-load probability mathematics has been generalized so that the effective load carrying capability of a new generating unit may be estimated using only graphical aids. A parameter m is introduced to characterize the loss-of-load probability as a function of reserve megawatts.
