FAQs on Base Load & Peak Load Plants, Power Systems, Electrical Engineering, GATE Video Lecture - Electrical Engineering (EE)

1. What is the difference between base load and peak load plants in power systems?
Ans. Base load plants are power plants that operate continuously at a high capacity to meet the minimum, constant demand for electricity. They provide a stable and reliable power supply to meet the base load demand. On the other hand, peak load plants are power plants that are used to meet the additional electricity demand during peak hours when the demand is higher than the base load. These plants are usually more flexible in terms of operation and can quickly ramp up or down their power output to meet the changing demand.
2. How do base load and peak load plants contribute to the stability of power systems?
Ans. Base load plants contribute to the stability of power systems by providing a constant and reliable power supply. They operate continuously, allowing the grid to maintain a steady power output and voltage level. This stability is essential for the smooth operation of other power plants and the overall reliability of the power system. Peak load plants, on the other hand, help in meeting the additional demand during peak hours, ensuring that the power system can handle the increased load without disruptions or voltage fluctuations.
3. What are some examples of base load and peak load plants?
Ans. Examples of base load plants include nuclear power plants and coal-fired power plants. These plants have a high capacity and operate continuously to meet the base load demand. They are designed to provide a stable and reliable power supply. Examples of peak load plants include gas-fired power plants and hydroelectric power plants with adjustable turbines. These plants have the flexibility to quickly increase or decrease their power output to meet the changing demand during peak hours.
4. How are base load and peak load plants economically beneficial for power systems?
Ans. Base load plants are economically beneficial for power systems because they operate continuously at a high capacity, which allows for efficient use of resources. These plants have lower variable costs per unit of electricity generated, making them cost-effective for meeting the constant base load demand. Peak load plants are also economically beneficial as they provide additional power during peak hours when the demand is higher. By ramping up the power output only when needed, the overall cost of electricity generation can be optimized.
5. How are power systems designed to accommodate base load and peak load plants?
Ans. Power systems are designed to accommodate base load and peak load plants by ensuring a balanced mix of generation sources. The capacity of base load plants is determined based on the minimum, constant demand for electricity. Additional capacity is then added through peak load plants to meet the increased demand during peak hours. The power system operators use load forecasting techniques to estimate the expected demand and schedule the operation of base load and peak load plants accordingly to maintain a stable and reliable power supply.
