非凸互补约束是能量约束优化问题中一个基本的计算难题。在这项工作中，我们提出了一个新的，线性的，强大的电池优化配方，回避了电池互补性约束和整数的需要，并证明了分析配方保证所有的能量约束得到满足，确保优化的电池调度是物理上可实现的。此外，我们限制了最坏情况下的模型失配，并讨论了保守性。仿真结果进一步说明了该方法的有效性。
The non-convex complementarity constraints present a fundamental computational challenge in energy constrained optimization problems. In this work, we present a new, linear, and robust battery optimization formulation that sidesteps the need for battery complementarity constraints and integers and prove analytically that the formulation guarantees that all energy constraints are satisfied which ensures that the optimized battery dispatch is physically realizable. In addition, we bound the worst-case model mismatch and discuss conservativeness. Simulation results further illustrate the effectiveness of this approach.
