摘　　要：文中采用割平面一致性算法对多区域动态经济调度问题进行分散式优化。每个区域均构建本区域的主问题对原问题进行近似,不同区域之间仅传递割平面约束,不需要上层的协调器。对割平面一致性算法进行如下改进:第一,区域之间仅传递最新的割平面以减少传递信息量;第二,当割平面约束在连续若干次迭代不起作用时将其删除以减少迭代次数。对不同规模的电力系统,文中方法均能够不调节参数直接解出正确的结果。通过对3区域IEEE RTS系统和一个实际4区域2298节点系统进行测试,证明文中方法的有效性。A cutting plane consensus algorithm was implemented to solve the multi-area dynamic economic dispatch of large-scale power systems in a fully decentralized way. A local master problem was constructed in each area to approximate the original problem, cutting planes are transmitted among different areas, so an upper coordinator is unnecessary. Two modifications were developed： firstly, only the newest cutting planes are transmitted among different areas to reduce amount of information transferred; secondly, the cutting plane will be deleted if it could be inactive during consecutive iterations to reduce the iterations. The convergence and correctness can be guaranteed for power system with a wide range of scales, and the convergence speed is independent from parameter tuning. Hence, the proposed method can be directly used in different power systems without adjusting parameters. The 3-area IEEE RTS system and a real 4-area 2298-bus provincial power system were tested to demonstrate the effectiveness of the proposed method.
