| 摘 要： | 发电侧放开竞争的电力系统需要更加有效、准确的决策工具对有限的资源进行调度规划。短期经济调度优化问题是一个混合整数非线性规划问题,很难得到有效最优解,尤其是对于大规模电力系统。为了提高求解效率,本文提出了一个考虑安全约束的经济调度优化模型(Security-Constrained Economics Dispatch,SCED),主要采用线性化思想处理经济调度优化问题的模型以及各种约束,采用基于校正的交替求解方法,使得调度优化结果在运行成本最小化的前提下满足系统的安全稳定约束。同时,将本文方法运用到IEEE 30节点系统进行测试,从而验证本文方法有效性。

| Abstract: | The competitive generation sicle in electricity system need to have more effective and accurate decision making tools for schedaling limited resources. The short-term economic dispatch optimization problem is a mixed integer nonlinear programming problem. It is difficult to get effectively optimal solution, especially for large-scale power systems. In order to improve the efficiency of solution, an economic dispatch optimization model considering security constraints(Security-Constrained Economics Dispatch, SCED)is proposed. Linearization method is used to process the optimization model and a variety of constraints. At the same time, this method is applied to the IEEE 30-bus system for test in order to verify the effectiveness of the proposed method. |
