When it comes to renewable energy, it is also necessary to deal with the other side of the coin: the problems of power grid instability.
By their nature, renewable resources are unpredictable and not always available. Energy grids powered by green sources are more prone to instability. Let’s see how electric battery energy storage systems (BESS) can be the solution.
Grid instability: what it is and what it entails
Wind and solar resources are variable. Winds may stop blowing and clouds may cover the sun and also solar panels. What does all this entail? A drastic drop in power output and grid instability.
In a power grid there are certain parameters that must work in sync. Variations in voltage, frequency and reactive power can damage entire sections of the grid, requiring protective relays to trip. All this results in problems throughout the grid and so-called security blackouts.
With the increasing deployment of renewables on grids without storage systems, power outages are occurring more frequently. To avoid overloads, some areas of the grid are disconnected.
This is an issue to be reckoned with in the context of the energy transition that is critical to the well-being of our planet. In a world increasingly devoted to the use of renewable energy, it is important to stabilize reactive power management. This is why battery-based energy storage systems (BESS) may be the solution to the problem.
How battery energy storage systems work
BESSs can store and conserve electrical energy. Batteries accumulate and store energy by absorbing excesses in the grid and ensuring its availability over time.
In this way, renewable energy can be integrated into the power grid, ensuring the necessary grid stability.
Energy storage systems are parks of rechargeable batteries, sets of batteries as large as containers. The batteries store and conserve energy to ensure continuity of supply during times of declining electricity by redistributing the stored energy.
BESS and grid stabilization.
A major goal to be achieved by 2030 is to help save the world from the adverse effects of climate change also caused by the exploitation of nonrenewable energy resources.
Electricity assumes an increasingly important role in this. To take full advantage of renewables, we need grids that can handle any newly introduced instabilities.
The need to harness and implement electricity storage systems is becoming more and more compelling from an efficiency perspective. This requires investment and new technology to serve the cause.
BESS solve the problem of grid instability induced by unstable energy sources, such as renewables.
Investing in energy storage systems is, to date, the right choice that Redelfi is pursuing, as a pioneer company in the industry and as an example for the not-too-distant future.
