Understanding the Power Grid 5th FS24

What is the primary function of a transformer in the power grid?

• To generate electricity

• To store electricity

• To step up or down voltages

• To convert AC to DC

Which type of current is predominantly used in the power grid?

• Pulsating Current

• Static Current

• Alternating Current (AC)

• Direct Current (DC)

What is the main advantage of using AC power in the grid?

• It is more stable than DC

• It allows easy voltage transformation

• It is easier to store

• It is cheaper to produce

What is the role of high voltage transmission lines?

• To store electricity for later use

• To convert AC to DC

• To minimize losses during electricity transport

• To generate electricity

What is a substation's function in the power grid?

• To generate electricity

• To store electricity

• To step down voltage and regulate electricity quality

• To convert AC to DC

What is the primary challenge in balancing electricity supply and demand?

• Dispatching generation capacity in real time

• Managing equipment faults

• Forecasting extreme weather

• Predicting consumer behavior

What is one of the benefits of a large power grid?

• It reduces the need for transformers

• It provides electrical inertia

• It increases the cost of electricity

• It allows for more power outages

What is the main reason for making the grid smarter?

• To improve efficiency and management of the grid

• To reduce the use of renewable energy

• To increase the number of power plants

• To eliminate the need for substations

What is the technical term for a power grid?

• Wide area interconnection

• Electrical network

• Energy circuit

• Power loop

What is the main purpose of grid operators?

• To generate electricity

• To balance demand by dispatching generation capacity

• To store electricity

• To convert AC to DC
