在线滚动调度是消纳大规模接入风电的重要环节，需要考虑包括机组调节次数以及出力离散化的发电调节约束。含这些发电调节约束的在线滚动调度模型是一个大规模的非线性混合整数规划问题，难以在有效的时间内完成严格的求解。文中提出一种考虑离散化发电调节约束的在线滚动调度的三阶段算法，其核心是一种具有多项式计算复杂度的前推—回推式动态规划算法。最后在IEEE 31节点系统和264节点系统上进行算例测试，以验证算法的高效性和实用性。

Look-ahead generation dispatch is a critical measurement to accommodate large-scale integration of wind power generation.In real application,the model for conventional generators should involve generation regulation constraints including regulation frequency constraints and discrete output constraints.Look-ahead generation dispatch with regulation constraints is a large-scale nonlinear mixed-integer programming problem,and it could be hardly solved strictly within acceptable time.An efficient three-stage method for solving this problem is developed, together with a forward-backward-pass dynamic programming approach for handling generation regulation constraints.Numerical tests are taken on IEEE 3 1-bus systems and a large-scale 264-bus power system to verify the high efficiency and practicability of the proposed method.
