Method for size optimisation of large wind-hydrogen systems with high penetration on power grids

► Electric grids with high wind penetration levels have operational problems. ► Hydrogen production and storage can mitigate impact on grids of wind farms. ► The study describes an optimisation method for analysing wind-hydrogen systems. ► Optimal size of the hydrogen plant gives the minimum hydrogen production cost. ► The minimum hydrogen production cost does not give the maximum peak shaving effect.
