Impact of renewable intermittency on grid stability: causes
Learn how intermittent renewable energy affects the power grid and what measures can stabilize it.
So, "unreliable" energy sources don't fare well with conventional grids. For a power grid, to remain stable, it needs to respond to volatility in voltage and frequency disturbances. For example, suppose more power is generated than consumed or more energy consumed from the grid than generated.
In the production of power with solar energy, the fluctuations in the supply and demand of energy for a particular place can cause instability in the grids. These fluctuations occur because the sunlight intensity in an environment with homes using solar panels, for example, varies from time to time.
Solar, wind and other renewables require management approaches that account for intermittency and other complicating factors. Grid updates, energy storage solutions, smart grid technologies and government policies that account for renewables can help increase grid stability while embracing cleaner energy.
Distributed energy sources can help grid stability by reducing the need for long-range electricity transmission, tempering demand spikes during peak periods and providing small backup sources of power throughout the grid. They also provide reliable electricity for owners if the main grid loses power due to transmission or substation problems.
