The smart grid is an enhancement of the 20th century electrical grid, using two-way communications and distributed so-called intelligent devices. [1]
In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as Voltage, voltage angles, real power and reactive power.
The improved flexibility of the smart grid permits greater penetration of highly variable renewable energy sources such as solar power and wind power, even without the addition of energy storage. Smart grids could also monitor/control residential devices that are noncritical during periods of peak power consumption, and return their function ...
Using a PMU, it is simple to detect abnormal waveform shapes. A waveform shape described mathematically is called a phasor.. A phasor measurement unit (PMU) is a device used to estimate the magnitude and phase angle of an electrical phasor quantity (such as voltage or current) in the electricity grid using a common time source for synchronization.
Meter data management (MDM) refers to software that performs long-term data storage and management for the vast quantities of data delivered by smart metering systems. This data consists primarily of usage data and events that are imported from the head-end servers managing the data collection in advanced metering infrastructure (AMI) or automatic meter reading (AMR) systems.
When prospecting such locations, the grid connection point must also be analyzed. Adding new generation to a grid typically requires an infrastructure buildup that can potentially cost millions of dollars. [3] In some circumstances a phenomenon, known as concurrent cooling, can be utilized to mitigate the expenses.
The term smart grid is most commonly defined as an electric grid that has been digitized to enable two way communication between producers and consumers. [1] The objective of the smart grid is to update electricity infrastructure to include more advanced communication, control, and sensory technology with the hope of increasing communication between consumers and energy producers.
The power transformer or battery-to-grid are critical aspects of power distribution and sizing and modelling of batteries or transformers depends on the load profile. [1] The factory specification of transformers for the optimization of load losses versus no-load losses is dependent directly on the characteristics of the load profile that the ...
