Title
Advanced Modeling and Optimization of Modern Power Systems: From Operations to Long-Term Planning
Abstract
Modern power systems increasingly require coordinated decision-making across power generation, transmission, and flexible demand resources to ensure reliable grid operations under uncertainty. This presentation discusses optimization and modeling frameworks that enable the joint consideration of planning and operational decisions in power and multi-energy systems, with particular emphasis on transmission expansion, energy storage, and demand-side flexibility. At the operational level, the presentation highlights coordinated optimization approaches that capture interactions between power networks and other infrastructures, such as water systems, enabling flexible resources to be scheduled alongside conventional grid assets. At the planning level, transmission and resource expansion models are used to illustrate trade-offs between network reinforcement and operational reliability under stressed system conditions. The presentation also introduces quantitative reliability and resilience metrics that link system performance, disruption, and recovery within a consistent analytical framework. Together, these elements demonstrate how integrated modeling approaches can support robust and computationally tractable decision-making for power system planning and operations in increasingly complex and interdependent energy systems.
