Optimized selection and operation of electrical energy storage systems

This paper presents a model to optimally select and operate energy storage devices attached to renewable energy generators connected to power distribution systems. The purpose is to supply a load during specific periods, considering the intermittence of the renewable energy resources and variable electricity rates. Thus, it was developed a database containing information obtained from catalogs of Lithium-Ion and Lead-Acid batteries manufacturers. The problem was formulated according to a mixed integer linear programming model, which was solved by LINDO™ code. A case study is presented and analyzed using the proposed methodology. The primary conclusions relate to the behavior of the proposed model in the short period of a day and how it should be improved in order to be adapted for a longer period.
