Abstract:

面向具有多级电力调度中心的分层分区互联电力系统,提出一种基于目标级联分析的分散协调风险调度(coordinateddecentralizedrisk-baseddispatch,CDRD)方法。分析了分散协调风险调度的架构,并给出了区域分解机制。将上下级电力调度中心的优化问题分别构建为主问题和子问题,主问题负责区域之间联络线潮流的协调处理,子问题求解满足各区域电网运行风险约束的调度方案,主子问题循环迭代求解直至满足收敛条件。CDRD可有效实现各区域电网运行风险的分散自治调控,同时可通过集中协调机制来保证整个互联系统的经济运行。在6节点双区系统和RTS96三区系统上的算例分析验证了算法的有效性和可行性。
