Operation Control with LAN System of YUGEMARU

Power System Operation and Control

The primary objective of power system operation is to deliver power to its customers meeting strict tolerances on voltage magnitude and frequency. Accordingly, the operation control problems naturally divide into control of voltage magnitudes or the voltage control issues, and the control of system frequency or the frequency control problems. Power system being an interconnected large system sp...

A Distributed Control Architecture for Autonomous Operation of a Hybrid AC/DC Microgrid System

Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...

Energy-Efficient PCF Operation of IEEE 802.11a Wireless LAN

In this paper, we demonstrate the energy-efficient Point Coordination Function (PCF) operation of IEEE 802.11a wireless LAN (WLAN) via both transmit power control (TPC) and physical layer (PHY) rate adaptation. First, we derive the energy-consumption performance analytically for uplink data transmissions under the PCF. From the evaluation results, we observe that significant energy savings can ...

DECT Wireless LAN System

Digital Enhanced Cordless Telecommunications(DECT) can carry both voice and data. The DECTLAN project at Centre for Wireless Communications (CWC) aims to develop a wireless LAN system based on the DECT standard. In phase I, the DECTLAN system supports a single duplex DECT bearer and an effective data rate of 24 kbps with no mobility support. In phase II of the project, the system will support 6...
