我们考虑一个微电网随机负载实现，随机可再生能源生产，和一个储能单元。电网控制器提供微电网应该呈现给主电网的总净负荷轨迹，并且如果需要，微电网必须施加甩负荷和可再生能源削减以满足该净负荷轨迹。微电网控制器试图操作本地能量存储单元以最小化在有限时间范围内的负载削减和可再生能源削减的风险。我们制定的存储单元的操作优化的问题作为一个有限阶段的动态规划问题。我们证明了多阶段的目标函数的能量存储是严格凸的电池在每个阶段的充电状态。最优决策的唯一性在一些额外的假设下被证明。从而得到最优策略。在模拟中示出的能量存储在减少甩负荷和可再生能源（RE）削减的有效性。
We consider a microgrid with random load realization, stochastic renewable energy production, and an energy storage unit. The grid controller provides the total net load trajectory that the microgrid should present to the main grid and the microgrid must impose load shedding and renewable energy curtailment if necessary to meet that net load trajectory. The microgrid controller seeks to operate the local energy storage unit to minimize the risk of load shedding, and renewable energy curtailment over a finite time horizon. We formulate the problem of optimizing the operation of the storage unit as a finite stage dynamic programming problem. We prove that the multi-stage objective function of the energy storage is strictly convex in the state of charge of the battery at each stage. The uniqueness of the optimal decision is proven under some additional assumptions. The optimal strategy is then obtained. The effectiveness of the energy storage in decreasing load shedding and renewable energy (RE) curtailment is illustrated in simulations.
