Question 1:

What is distributed power generation?

A) Centralized power generation at large power plants
B) Power generation using renewable energy sources only
C) Power generation using small-scale systems close to the point of use
D) Power generation using fossil fuel sources only

Show Answer

Explanation: The correct answer is C) Power generation using small-scale systems close to the point of use. Distributed power generation refers to the generation of electricity using small-scale power systems located near the end-users or the point of consumption. It can include various technologies, such as solar panels, wind turbines, fuel cells, and microturbines. Distributed generation offers benefits like increased energy efficiency, reduced transmission losses, and enhanced grid resilience.

Question 2:

What is a microgrid?

A) A small-scale power plant
B) A grid system that supplies power to a single building
C) A grid system that operates independently or in coordination with the main power grid
D) A grid system powered solely by renewable energy sources

Show Answer

Explanation: The correct answer is C) A grid system that operates independently or in coordination with the main power grid. A microgrid is a localized energy system that includes power generation, energy storage, and loads, all connected together as a single entity. It can operate independently, known as island mode, or in coordination with the main power grid. Microgrids often utilize distributed energy resources and can enhance grid resilience, improve energy efficiency, and support renewable energy integration.

Question 3:

What is the main benefit of distributed power generation?

A) Reduced dependency on the main power grid
B) Lower capital costs for power generation
C) Increased reliability and resilience of the power supply
D) Higher energy efficiency compared to centralized power generation

Show Answer

Explanation: The correct answer is C) Increased reliability and resilience of the power supply. Distributed power generation offers benefits such as increased reliability and resilience of the power supply. By generating electricity close to the point of use, distributed power systems can reduce the risk of widespread power outages caused by disruptions in the main grid. They can also enhance grid stability and provide backup power during emergencies or natural disasters.

Question 4:

What is the purpose of energy storage systems in a microgrid?

A) To store excess electricity generated by the microgrid
B) To provide backup power during grid outages
C) To balance power supply and demand within the microgrid
D) All of the above

Show Answer

Explanation: The correct answer is D) All of the above. Energy storage systems play multiple roles in a microgrid. They can store excess electricity generated by the microgrid when the demand is low and release it when the demand exceeds the generation capacity. Energy storage systems also provide backup power during grid outages or serve as a buffer to balance power supply and demand within the microgrid, optimizing the overall energy usage.

Question 5:

What is the key advantage of microgrids compared to traditional centralized power grids?

A) Higher energy efficiency
B) Lower carbon emissions
C) Enhanced grid resilience
D) Lower electricity costs

Show Answer

Explanation: The correct answer is C) Enhanced grid resilience. One of the key advantages of microgrids compared to traditional centralized power grids is their enhanced grid resilience. Microgrids can operate independently during power gridoutages, ensuring a continuous power supply to critical facilities or communities. They can isolate themselves from the main grid and rely on local generation and energy storage, reducing the impact of grid disruptions. This enhanced resilience makes microgrids a valuable solution in areas prone to natural disasters or remote locations with unreliable grid infrastructure.
