ITPEC FE Subject A April 2026 Question 53
Which of the following is an explanation of a smart grid?
Explanation
A system that controls power generation and consumption together through communication and information processing — a smart grid is an electricity network made intelligent.
It links power plants, renewable sources, storage, smart meters and appliances with a communication network, so information flows both ways along with the electricity. Supply and demand can then be balanced in real time, fluctuating renewable output absorbed, and peak demand adjusted.
Answer (a)
Why not others:
- •(b) — a health-advice system analysing examination and medication records
- •(c) — telematics, in-vehicle information services for navigation, traffic and emergency location
- •(d) — telework support, communication tools for employees with varied working styles
Key rule: When every option is IT applied to some domain, first identify the domain the term names: a "grid" is the power network, so only the electricity option fits.
