考虑电网多元风险的输电断面动态增容调度分配方案

Distribution Scheme for Dynamic Capacity-Increase of the Transmission Section with Considering the Multi-risk of Power Grid

针对目前电网输电断面增容容量分配决策的相关问题,提出一种考虑电网多元风险的输电断面动态增容调度分配方案优化模型。该模型考虑了电网面临的多元风险约束,包括设备健康风险、气象风险和系统异常风险。其中,断面内通道的容量裕量限额是通过三大定容设备——变压器、断路器以及输电线路的动态增容计算模型得到的。所提出的考虑电网多元风险的输电断面动态增容调度分配方案,可以较好地平衡大电网电能输送中的经济性和安全性问题,为解决输电断面内动态增容分配提出了一个新的解决思路和技术方案。

In view of the decision-making issues related to the distribution of dynamic capacity-increase of transmission section, a distribution scheme optimization model is proposed in this paper for transmission section dynamic capacity-increase with consideration of the multi-risk of power grid. The model developed in this paper takes multi-risk constraints into consideration, which include health risk of power equipment, weather risk and system anomaly risk. The capacity limits of the transformer, breaker and transmission line are determined by capacity-increase calculation model. The proposed distribution scheme can balance the economy and security in power transmission of large power grids and provide a possible solution and technical scheme for dynamic capacity-increase distribution of transmission section.
