Practical aspects of storage modeling in the framework of microgrid real-time optimal control

One of the important aspects of microgrids in the long-term is the optimization of power generation. A real-time optimization-based controller can determine the optimal contribution of multiple generation assets or storage devices within the microgrid to meet the demand at minimum operation or emission costs. Since storage devices are indispensable components of microgrids, especially when intermittent power generation sources are employed, their appropriate modeling in this optimization framework is of crucial importance. This paper discusses in detail the technical complexities associated with the practical consideration of storage devices within the framework of microgrid power generation optimization problems, as well as presenting feasible solutions to address these problems.
