Extending electric grid physics to implement smart grid trading function — •Thomas Walter and Bernd Brunner — Wirsol Integrated PV Solutions

Renewable energy (RE) sources like solar and wind can now compete on generation cost with some fossil sources, but have the property of being volatile. Traditional concepts use storage of electric energy to compensate for this volatility. However, storage cost exceeds generation cost until major breakthroughs will be achieved. Electric grids in which reneable energies provide the larger share (RE dominated grids) therefore utilize the flexibility of decentral loads and generation units. If these are shifted suitably in time, they can utilize too high RE production, and supply energy when RE production is too low. The paper shows how the well known effect that grid freguency varies according to the balance of supply and demand can be utilized to build the basis of a smart grid. This system simplifies overall complexity and reduces cost by appropriate combination of physics and data based technologies.
