A sustainable vision of the new power network. integrating energy storage

FuturENERGY April-May 2020

We are all aware of global warming, but what does this means and how does this impact on the expected quality of life for an electrical engineer? Nobody wants to give up the living standard for which we have worked so hard and both society and industry are now so dependent on a high-performance mains supply that any failure of the grid to supply power is regarded as a crisis. Danfoss is taking an active part in hybridisation and energy storage in different applications, developing the tools needed for energy flow, load-levelling and safe operation for next generation grids, focusing on a sustainable future.

One region of India has already installed 12.3 GW of renewable energy, with 7.8 GW in Denmark and 7.7 GW in the Netherlands. California recently peaked at 10.5 GW of renewable production, whereas the global growth rate is 8-9% annually. But even so, renewables remain a minor player in terms of network capacities and society is still reliant on fossil fuel-based power plants. Firstly, wind and sun are not necessarily available when the consumer needs the energy. Secondly, large rotating masses in big power plants provide stability to the grid. Therefore, renewable energy production may be cut back in periods, in order to deal with grid challenges, congestion management and balancing costs.
