Abstract:

Severe geological disasters can lead to major power outages, posing serious threats to the safe and stable operation of power grids. To address the impact of geologic disasters on power grids, a power system security scheduling strategy based on disaster risk mapping is proposed. First, a disaster risk mapping strategy is constructed based on a variety of disaster impact factors, and the hazardous situation of the transmission line is obtained by overlaying this map with the geographic location of the transmission line. Then, a power system operation risk model is established to quantitatively analyze the risk of the system using composite risk indexes. Finally, a particle swarm algorithm is used to construct the regulation strategy of generators and flexibility resources using the New England power system as a case study to validate the effectiveness and feasibility of the strategy. The results show that the proposed power system security scheduling strategy can effectively reduce the comprehensive risk indicators, including the risk of power system overrun/heavy load, enhancing the security and stability of power grid operations.

Key words: geohazards, risk mapping, overrun/heavy load risk, flexibility resources
