Abstract:

The grid connection of intermittent energy sources such as wind power and photovoltaic power generation brings new challenges for the economic and safe operation of renewable power systems. To address these challenges, a multi-time-scale active power coordinated operation method, consisting of day-ahead scheduling, hour-level rolling corrective scheduling, and real-time corrective scheduling, is proposed for the combined operation of wind-photovoltaic-thermal-hydro power and battery (WPTHB) to handle renewable power fluctuations. In day-ahead scheduling, the optimal power outputs of thermal po

Abstract:

This research proposed an accurate Duty Cycle Correction (DCC) circuit for high-frequency systems with high measurement accuracy. It is a crucial component of Very Large Scale Integration (VLSI) circuits and is applied as a percentage of the measured average power of a modulated signal to obtain the signal power. This circuit uses two stages of correction, with the first stage performing course correction and the second stage performing fine corrections. This allows the power to be determined during the pulse given the measurement of the average power of a modulated signal with a known duty cy

Methods for correcting data from gas turbine acceptance testing are discussed, focusing on matters which are not sufficiently covered by existing standards.

Typical performance correction curves are shown together with the method of calculating mass flow rate and turbine inlet temperature from test data. A procedure for verifying guarantee data at a specific operating point is then given. Operation with water injection is then considered.

Abstract We revisit the one-loop correction in curvature perturbation power spectrum in models of single field inflation which undergo a phase of ultra slow-roll (USR) inflation.

It is shown that the amplitude of one-loop corrections depends on the sharpness of the transition from the USR phase to the final slow-roll phase. For an arbitrarily sharp transition,

Abstract The actuator line method for modeling wind turbine blades in wind farm flow simulations often offers a good compromise between accuracy and computational cost. A variety of methods have been proposed to correct the force prediction by the actuator line near the tip and root due to smearing the force in the flow domain. This article compares the two most commonly used methods (the filtered lifting line and the vortex-based smearing correction) in terms of accuracy, applicability and computational performance.

However, its computational cost exceeds that of existing tip corrections and quickly grows with blade discretization.

Abstract:

For the equipment connected to the three-phase or single-phase grid, the power factor represents an efficiency measure for the usage of electrical energy. The power factor improvement through correction methods reduces the load on the transformers and power conductors, leading to a reduction of losses in the mains power supply and a sustainable grid system. The implications at the financial level are also important. An example of load that generates a small power factor is represented by a motor without mechanical load or having a small mechanical load. Given the power factor correction (PFC),

Abstract— Automatic power factor corrector is designed to improve power factor automatically whenever power factor falls below a certain level. Efficient generation of power at present is crucial as wastage of power is a global concern. As we know, the demand for electrical energy is increasing day by day. Power factor measures a system’s power efficiency and is an important aspect in improving the quality of supply. This paper presents an embedded system for automatic power factor correction with comprehensive power measurements via LoRa wireless communication. It comprises two Arduino Uno-ba

Abstract:

With the development of industrial power electronics, the current era can be called the "world energy era". Energy has never been more important, especially with the growing demand for today's "green" energy sources. power factor correction circuits have become an integral part of most current AC voltage input power applications, whether it is automotive battery power, portable energy storage (such as power banks), traditional server power, or lighting systems. However, the basic principles of power factor correction converters are rarely described in detail. This paper will summarize and illu

Abstract:

In today’s world, the extensive visual load increases the demands on the quality of optical correction. Inadequate optical correction results in additional load on the accommodation system of the eye, increased fatigue, and complaints of asthenopia. Full optical correction is an essential requirement for the correct functioning of a visual analyzer. However, if baseline impairments of accommodation response (fusion) are not considered, full optical correction (eyeglasses or contact lenses) provokes visual discomfort.

Abstract:

Abstract: In today's technological revolution, power is very valuable. Low power factor results in increased energy consumption, voltage drops, decreased power system efficiency, and shortened equipment lifespan. Identifying the causes of power loss and improving power system stability is crucial. The rise in inductive loads has decreased power system efficiency. Therefore, a simple and effective method for improving power factor is needed. An automatic power factor correction device precisely determines the delay between the line voltage and line current by measuring the time difference betwe
