The multi-energy-storage-technology test-case was effectively applied to achieve 100%-renewable energy generation for the town of Ohakune, New Zealand. Numerical simulation results suggest that the proposed incentive-compatible demand-side management market-clearing mechanism is able to estimate the cost-optimal solution for
Additionally the DC energy storage in the form of electrolytic capacitors determines and shortens a converter''s life time [32]. Unfortunately the aluminum electrolytic capacitors which are usually used in AC–AC converters as energy buffers and to filter off the AC voltage ripples are one of the most expensive and most likely to fail components in a
