Sizing and power management strategies for battery storage integration into wind-diesel systems

Battery energy storage systems can be used in wind-diesel systems to offset diesel fuel and potentially reduce the cost of the energy served by limiting the amount of dumped energy. However, this problem is characterized by two components: energy storage sizing and its on-line operation. This paper presents a energy storage sizing approach, which is then adapted for on-line scheduling. The operating algorithm is presented with and without consideration being given to the batterypsilas state-of-charge over time. The results from the storage sizing and operation problems are compared and further considerations are highlighted.
