摘要

极端气象灾害的日益频发，给电网安全稳定运行带来了极大的威胁。传统电力系统的经济调度方法为了追求发电成本的经济性而忽略了电网载荷分布状况，在恶劣天气条件下重载或是满载线路的停运都可能引发电力系统连锁故障大停电事故。为此，提出了一种恶劣天气条件下考虑电网载荷均衡度及

安全约束的防灾经济调度方法。该方法在传统经济调度模型的基础上，综合考虑全网和恶劣天气影响区域输电线路载荷的状况，通过降低全网输电线路载荷率的平均绝对偏差以及恶劣天气下区域输电线路载荷率，改善电网的载荷均衡度，并提高系统的运行安全。为保证调度模型在恶劣天气条件下的鲁棒性及求解高效性，基于支路开断分布因子以及校验添加再校验思想，提出了一种新的

安全约束动态校核及添加方法。最后，基于现有的考虑隐性故障的连锁故障仿真模型，提出了在台风灾害下电力系统防灾经济调度策略的可靠性评估方法。IEEE RTS-79系统的仿真结果表明，相比于传统经济调度方法，所提出的防灾经济调度方法能够有效地提高电网载荷均衡度，改善恶劣天气条件下电力系统的停电分布，并可提高系统运行安全性及可靠性。

Abstract

The increasing frequency of extreme meteorological disasters is posing a great threat to the safe and stable operation of power grid. The traditional economic dispatch method of power system aims at pursuing the economics of the generation costs

while ignoring the load distribution condition of power grid. The outage of heavy or full load lines will lead to the cascading failure and the blackout of power system. To solve this problem

a blackout-prevention economic dispatch method considering load rate homogeneity of power grid and

N-

1 security constraints is proposed for extreme whether conditions. Based on the traditional economic dispatch model

and comprehensively considering the load rate distribution of the whole power grid and the transmission lines affected by extreme weather

the load rate distribution balance is improved by reducing the average absolute deviation of the load rate of the entire power grid and the load rate of transmission lines in extreme weather areas

the operation security of power system is consequently enhanced. To ensure the robustness and high solving efficiency of the model in extreme weather

a novel method for dynamically checking and adding

N-

1 security constraints of transmission lines is proposed based on a check-feed-back-check idea and the line outage distribution factor (LODF) of transmission lines. Finally

a reliability evaluation method for dispatch strategies of power system in typhoon disaster is proposed based on the existing cascading failure simulation model considering hidden failures. Simulation results of IEEE RTS-79 test system show that

compared with the traditional economic dispatch method

the proposed dispatch method can effectively increase the load rate homogeneity of power grid

and improve the blackout distribution of the power system under extreme whether condition

thus improving the system operation safety and reliability.
