Energy Storage Systems (ESS) have an impressive track record for providing stability and efficient power management in power system. With recent technological advancements and the decline in costs, the use of battery for ESS is gradually becoming popular in the power industry. In particular, Lithium-ion Battery (LiB) is being used in various power grids around the world. In Jocheon, Jeju Island...
Objective: The present research aimed to determine the effectiveness of interpersonal and social rhythm therapy on alexithymia and self-regulation in individuals with substance use disorder in outpatient centers. Method: The current research was semi-experimental with a pretest-posttest design with a control group. The statistical population of the research included all men with substance use d...
Pain is the most popular stress that human face with. This study aimed to determine the fitness of emotion regulation model of generalized anxiety disorder to explain the perception of pain in patients with chronic pain. This study was conducted in the context of a correlation research the type of structural equation. The sample were consisted of 210 patients referred to a specialized pai...
The progress of semiconductor technology and control systems the last years has made possible the realisation of highly efficient and low priced microprocessor-based controllers for the control of asynchronous motors. This paper describes the design and realization of a microcomputer-based device for frequency regulation of an asynchronous motor. Through the regulation of motor’s supply frequen...
We analyze the cost of curtailing the active power output of a wind farm to provide secondary frequency regulation capacity. We calculate the regulation capacity available and its cost by simulating the active power output of a curtailed 100-MW wind farm with a hybrid of real speed data and simulated high-frequency turbulence. We find that a curtailed wind farm can provide secondary frequency r...
Background and purpose: In developmental process, children use gestures for communication. One of these gestures is reaching which has various communicative functions. The purpose of this research was to investigate the development of reaching and its communicative functions in normally developed children aged 8-12 months whose language was Persian. Materials and methods: This longitudinal...
This paper presents a Frequency Regulation (FR) model of large interconnected power system including Energy Storage Systems (ESSs) such as Battery (BESSs) and Flywheel (FESSs), considering all relevant stages in the frequency control process. Communication delays are considered transmission signals FR loop ESSs, their State Charge (SoC) management is considered. The system, ESSs SoC components ...
