The SCALE prototype board has been fabricated and consists of a single Xilinx XC2V4000 FPGA connected to a number of Micron DDR2 DRAMs that form the SCALE memory system. To support power measurements, the board is divided into multiple separate power islands. The board is attached to a test baseboard that provides sixteen independently measurable power supply connections and a byte-serial conne...

Automatic Meter Reading (AMR) is the remote collection of consumption data from customer’s utility meters over telecommunications, radio, power line and other links. AMR provides water, electric and gas utility−service companies the opportunities to streamline metering, billing and collection activities, increase operational efficiency and improve customer service. Utility company uses technolo...

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...

The power system training simulation software, exist in the market, emphasis on the network structure and flow calculation without the local details or equipment operation, or focus on one or two substations, but ignoring the power of the substation. With more and more complex structure of the domestic power grid, and increasing scale of power, the existing power system simulation software cann...

the ultimate goal of power system operation and planning is to increase power system reliability which enforces interconnected operation of power system. as a result of power system interconnection, the inter-area oscillation under different disturbances may cause power system partial or total blackout. dc-segmentation of interconnected power systems is a solution in which the topology of the n...

<span lang="EN-US">Large-scale grid-tied photovoltaic (PV) station are increasing rapidly. However, this large penetration of PV system creates frequency fluctuation in the grid due to intermittency solar irradiance. Therefore, paper, a robust droop control mechanism battery energy storage (BESS) is developed order damp multi-machine variable active power injected from panel. The proposed...

After occurrence of some disturbances in power system that causes the sever imbalance between generation power and electrical load, the power system frequency begins to decrease. To prevent power system frequency instability and stop the frequency decay below the power system allowable frequency limitation, load shedding schemes should be utilized by applying under frequency load shedding relay...

with the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...
