it is possible for an excess of power generation, particularly from decentralized sources like solar panels, to cause issues in the power grid, including congestion and even blackouts. This can happen if the grid is not equipped to handle the variability and amount of power being fed back into it. Here’s a more detailed explanation:
Grid Congestion: When many prosumers (consumers who also produce energy) feed their excess solar power into the grid simultaneously, it can create congestion. This means the power lines and substations become overloaded with the surplus electricity.
Voltage Fluctuations: Excess energy can lead to fluctuations in voltage levels. The grid is designed to operate within specific voltage limits, and significant deviations can cause damage to infrastructure and affect the stability of the grid.
Frequency Instability: The balance between power supply and demand is crucial for maintaining the frequency of the grid. A large influx of solar energy can disrupt this balance, leading to frequency instability, which can cause blackouts.
Lack of Storage: Without adequate storage solutions, excess energy cannot be utilized efficiently. Energy storage systems, like home batteries, can store the surplus power generated during peak production times (e.g., sunny days) and release it during periods of high demand or low production (e.g., cloudy days or nighttime).
Everything you mention is not a problem. Grid operators change prices to match supply and demand. Electricity markets are 24/7 and prices range from negative to extremely high to maintain supply and demand in perfect balance.
When there is excess renewable production, shut down other production like Natural Gas. There is zero fuel cost. If other productions can't be shut down, change the price to negative, charge EVs and pay them money for letting us use their storage capacity.
