The Insertion of Energy Storage Systems in Power Systems: A Regulatory and Economic Analysis

This work presents a methodology to analyze the insertion of energy storage systems in power systems in different economic scenarios and regulatory frameworks. The paper uses technical and economic data from international benchmarks to determine the scenarios in which investment in energy storage systems may be feasible. Evaluating 8 regulatory policies and using different levels of capital cost and taxes, the paper evaluated more than 58 thousand possible scenarios. The objective in each scenario is to determine what could be the maximum feasible cost for installing energy storage systems and thus indicate how these investments could be made in power systems. In this way, the methodology allows to evaluate any energy storage technology and indicate which regulatory changes could be made considering the economic environment being evaluated.
