Sample interview questions: Can you explain the role of hydroelectric power plants in grid stability and reliability?
Sample answer:
Hydroelectric power plants play a vital role in ensuring grid stability and reliability by providing a consistent and reliable source of electricity. They offer a range of benefits that contribute to the overall stability of the power grid.
Firstly, hydroelectric power plants have the ability to respond quickly to changes in electricity demand. Unlike some other renewable energy sources such as solar or wind, hydroelectric plants can rapidly adjust their power output to match the load requirements. This flexibility allows hydroelectric power plants to provide a stable supply of electricity, helping to maintain grid stability during peak demand periods.
Additionally, hydroelectric power plants act as a form of energy storage. By controlling the flow of water through the turbines, operators can store energy by reducing or increasing the power generation as needed. This stored energy can be released during periods of high demand, providing a reliable and stable supply of electricity. Hydroelectric plants can also be used to balance intermittent renewable energy sources, such as wind or solar, by compensating for their variability and ensuring a consistent power supply.
Furthermore, hydroelectric power plants offer inherent grid stability due to their ability to provide both active and reactive power support. Ac… Read full answer
