This article presents a methodology aimed at improving mid-term power system resilience at transmission substations in areas potentially affected by floods, combining hardening strategies and quantitative.
How to improve power system resilience to floods at transmission substations?
Mid-term power system resilience improvements to floods at transmission substations. Impact assessment considering hydrological model and location of electrical equipment. Accumulated cost and load energy unserved used as metrics separately. Mixed-integer linear programming formulation for optimal hardening of substations.
Conclusion Floods may be catastrophic to power systems in terms of damage to infrastructure and power outage. To assess the impact of floods on the grid and further define appropriate mitigation strategies, this article integrates multidisciplinary perspectives and sources of information within an optimization problem formulation.
Do mitigation alternatives improve power system resilience to floods?
Overall, the results indicate that investing in mitigation alternatives is advantageous not only to improve power system resilience to floods over a range of scenarios, but also to reduce costs and inconveniences associated with loads lost, operation in reserve mode, and damaged equipment.
A performance analysis of STATCOMs for a wind power system (WPS) with other FACTSs was conducted to examine the voltage, active power, and reactive power of the load bus comprising different loads, 36 with the results suggesting the incorporation of FACTSs to achieve a more stable structure of the WPS.
Should substations flooded be prioritized with optimal resilience planning?
In addition, note that the substations flooded in most scenarios are not necessarily prioritized with optimal resilience planning using (1) or (2). Again, the technical specifications and system effects of the substations disabled in each flood scenario play an important role in the resilience metrics and cost indicators.
In this respect, the analysis of the network bandwidth is very important to minimize the amount of ETE delay. The implementation of a communication network architecture based on wireless or hybrid wired/wireless connection can lead to the lowest possible ETE delay in the future wind power systems.
