N2 - In this study, wind-battery hybrid power systems are designed, evaluated, and optimized for regular supply of electrical power at a designated minimum load level with no shortage. Our simulation uses lead-acid batteries and vanadium redox flow batteries (VRBs) for storage, and utilizes hourly wind speed data measured in 2012 at Mt. Taegi in South Korea. Twenty Vestas V80 wind turbines, each rated at 2 MW, are used as power generators, on the basis of an actual wind turbine project recently installed at Mt. Taegi. Sale to the main grid of electricity generated in excess of the minimum load offset the initial capital costs for installation of the wind turbines and batteries. Results show that the optimized wind-VRB hybrid system can supply more than 9 MW of regular electrical power at no cost. Even higher levels of production are profitable with sale of the wind-generated electricity directly to a demand site at a price greater than the price of sales to the main grid. A reduction in the VRB electrolyte costs and an increase in carbon taxes can also increase profitability.
