摘要
为适应我国目前多级调度管理体制,促进分层分区经济调度实施,提出求解互联电网经济调度的层级协调方法。首先,基于层级调度协调运作的思想,建立区域协调中心和分区调度的层级协调运作机制,进而通过层级之间的信息交互实现解耦优化;然后基于序列无约束化方法(SUMT)的二次罚函数法,构建区域协调中心和分区的层级协调优化模型,分别采用拟牛顿算法和原对偶内点算法求解。IEEE30测试系统表明,层级协调是一种新颖而有效的方法,可以用于求解互联电网经济调度,能够方便实现区域协调中心的一对多全局控制目标。
In order to adapt to the current multi-level dispatching management system and to promote the implementation of economic dispatching, this paper proposes the hierarchy coordination method for economic dispatching of interconnected power systems. First, the two-level coordination mechanism between area coordination center and sub-areas is established based on the idea of hierarchy dispatching coordination operation. In this way, there would be decomposition optimization through information interaction between the two levels. Second, two-level coordination models are established based on quadratic penalty function method of SUMT. The quasi-Newton method and primal-dual interior point method are adopted respectively to solve these two models. The IEEE30 system demonstrates that this new approach can be used to optimize the economic dispatching of interconnected power systems. Furthermore, this approach proves effectiveness for the area coordination center to achieve one-to-many control and to gain an overall control of the whole area.
