With frequency stability being challenged in modern power systems, transmission system operators have been designing new mitigation measures, such as fast response (FFR), to maintain operation security of systems. To accommodate technical requirements control services (FCSs), the corresponding should be implemented at asset controllers enable responses. However, counteraction can arise between ...

The load frequency control system aims to regulate the in electric power at a normal value with predetermined tolerance limit. In practice, does not always operate optimally, therefore controller is needed be added system. designed variation of combination Proportional-Integral-Differential (PID) controllers standard model PIDTune method consisting proportional (P) controller, integral (PI) dif...

Variation of frequency and voltage by load changes in a microgrid is a challenge in droop control method. Centralized restoration frequency or voltage in a microgrid requires communication link and therefore affects the advantage of decentralized droop control such as reliability, simplicity and inexpensiveness. This paper proposes a decentralized method that restores the frequency of a microgr...

In this paper, we propose the introduction of a frequency domain variable perturbation control and a leaky algorithm to the frequency domain time difference simultaneous perturbation (FDTDSP) method in order to improve the cancellation performance and the stability of the active noise control (ANC) system using the perturbation method. Since the ANC system using the perturbation method does not...

As a technology solution, radio frequency identification (RFID) has proven increased efficiency and accuracy within traditional production and inventory control environments. RFID also offers increased transparency, accountability, and quality across the healthcare industry. This paper provides an a priori perspective to implementing RFID applications in a hospital environment. The paper descri...

This paper presents a frequency offset estimation scheme for Orthogonal Frequency Division Multiplex (OFDM) direct conversion receivers. The key idea is to use a differential filter for reduction of DC offset. Frequency offset is estimated in the presence of time-varying DC offset. In order to overcome the varying DC levels under automatic gain control (AGC) circuits, a threshold level is set f...

1 Networked RFID in Industrial Control: Current and Future This paper introduces the notion of networked Radio Frequency Technology (RFID) and reviews the work of the Auto ID Center in providing a low cost, global networked RFID solution. The paper then examines the role of networked RFID in changing the nature of industrial control systems operations. In particular the notions of connectedness...

The WCDMA system, an asynchronous CDMA scheme, uses different downlink scrambling codes for each base station, not requiring synchronization between the base stations as in the synchronous CDMA systems. However, the mobile station needs to obtain initial code synchronization by resolving both the code and timing uncertainty. The 3GPP group adopts the use of a three-step cell search scheme [1]. ...

The paper summarizes our preliminary findings regarding the development and implementation of a newly proposed system based on ICT and RFID (Radio Frequency Identification) technologies for campus access and facility usage. It is generally acknowledged that any educational environment is highly dependent upon a wide range of resources or variables such as teaching staff, research and study area...
