Optimal sizing and location of vanadium redox flow battery in a power system with high wind power generation

This paper proposes a new approach to determine the optimal sizing and location of a vanadium redox flow battery (VRFB) that provides load frequency control services in a power system, with the lowest cost for the utility grid. To this aim, the optimization model takes into account the impact of the energy storage system on the electrical system. With a stochastic optimization, the developed methodology calculates the operating costs of the electricity grid and the investment costs of the VRFB. The methodology uses a primary-dual interior point algorithm integrated in a meta heuristic algorithm and nested in an exhaustive search method.
