Research on Sensitivity of Power Loss Based on Injection Power

电力网损是电力系统经济运行所关注的重要问题之一,是评估供电单位电力生产经营的一项重要技术经济指标。文中以各节点注入功率的网损灵敏度作为网损影响程度评估的量化指标,提出了一种基于注入功率的各节点网损灵敏度评估方法。研究了电力网络各节点注入功率对网损的影响,计算出各节点注入功率的网损灵敏度,定量分析了节点的注入功率对不同节点网损的影响特性。以IEEE节点系统作为算例,基于Matlab软件对其进行仿真分析,结果表明论文所提出的算法为降低网损提供了理论依据。

Power network loss is one of the most important issues in the economic operation of power system. It is also an important technical and economic index for evaluating the production and operation of power supply units. Using the sensitivity of injected power of each node as a quantitative index for evaluating the impact of network loss, this paper presentes a method for evaluating the sensitivity of each node based on injected power. This paper studies the influence of injected power on network loss of each node in power network, calculates the sensitivity of injected power of each node, and quantitatively analyses the influence characteristics of injected power of each node on network loss of different nodes. Taking IEEE nodes system as examples, simulation analysis is carried out based on MATLAB software. The results show that the proposed algorithm provides a theoretical basis for reducing network loss.
