Modeling and simulation of sector-coupled networks: A gas-power benchmark

Can models for long-term decarbonization policies guarantee security of power supply? A perspective from gas and power sector coupling

The assessment of adequacy and security of the energy system requires the detailed knowledge of physical and operational characteristics. In contrast, studies concerning energy transitions employ stylized models that oftentimes ignore the technical properties but have a lasting influence on long-term energy policies. This paper investigates the gap between energy system planning and operational models by linking these two perspectives: (1) a long-term investment model with low spatial resolution and high level of aggregation, and (2) a spatially resolved system security model that captures the…

Synchronization of nonlinearly coupled networks of Chua oscillators

本文提出了新的充分条件，用于保证由非线性耦合的Chua振荡器网络通过第一个状态坐标连接时的同步，其中非线性耦合强度由一个扇区内的函数控制，即该函数被上下界线性函数所限制，所推导的充分条件在扇区特性和网络连接拓扑之间提供权衡以保证振荡器的同步。

Time Aggregation Techniques Applied to a Capacity Expansion Model for Real-Life Sector Coupled Energy Systems

Simulating energy systems is vital for energy planning to understand the effects of fluctuating renewable energy sources and integration of multiple energy sectors. Capacity expansion is a powerful tool for energy analysts and consists of simulating energy systems with the option of investing in new energy sources. In this paper, we apply clustering based aggregation techniques from the literature to very different real-life sector coupled energy systems. We systematically compare the aggregation techniques with respect to solution quality and simulation time. Furthermore, we propose two new c…
