What long-term solutions are suggested or implied to handle future grid instability issues resulting from an increasing share of renewable energy in the power grid?

The incident highlights the challenges of integrating renewable energy into existing grids. Wider use of smart meters and dynamic tariffs could enable more effective demand-side management, mitigating future gridlock scenarios and reducing the need for costly redispatches. This incident also emphasizes the financial impact of grid instability on consumers via increased net charges.

How can the bidirectional charging capability of electric vehicles contribute to a more sustainable and cost-effective energy system?

Electric vehicle (EV) batteries, ranging from 40 kWh (Renault R5) to 77 kWh (VW ID.4), can power homes and feed electricity back into grids via bidirectional chargers. This V2G (Vehicle-to-Grid) technology uses excess solar power stored in EV batteries during the day to supply homes at night, potentially saving households money and reducing reliance on additional home battery storage.
