A linear and convex model has been recently presented for the operation of battery energy storage units that does not explicitly prevent their simultaneous charge and discharge in the problem formulation. This letter claims that the model in such a literature contribution is capable of ensuring the physical realizability of the battery dispatch only when nondiscrete decisions are considered in the optimization problem. This claim is demonstrated through the solution of two instances of a simple unit-commitment-based example comprising two generating units, one battery energy storage unit, and two time periods.

确保单元承诺问题中物理可实现的存储操作


最近提出了一种用于电池储能单元运行的线性凸模型，该模型在问题公式中没有明确阻止它们同时充电和放电。这封信声称，只有在优化问题中考虑非离散决策时，此类文献贡献中的模型才能确保电池调度的物理可实现性。这一主张是通过一个简单的基于单元承诺的示例的两个实例的解决方案来证明的，该示例包括两个发电单元、一个电池能量存储单元和两个时间段。
