An Uncertainty Management Framework for Integrated Gas-Electric Energy Systems
Line A. Roald, Kaarthik Sundar, Anatoly Zlotnik +2
In many parts of the world, electric power systems have seen a significant shift towards generation from renewable energy and natural gas. Because of their ability to flexibly adju…
Chance-Constrained AC Optimal Power Flow: Reformulations and Efficient Algorithms
Line Roald, Göran Andersson
Higher levels of renewable electricity generation increase uncertainty in power system operation. To ensure secure system operation, new tools that account for this uncertainty are…
Battery Degradation Maps for Power System Optimization and as a Benchmark Reference
Philipp Fortenbacher, Göran Andersson
This paper presents a novel method to describe battery degradation. We use the concept of degradation maps to model the incremental charge capacity loss as a function of discrete b…
Impact of Dynamic Line Rating on Dispatch Decisions and Integration of Variable RES Energy
Bolun Xu, Andreas Ulbig, Goran Andersson
Dynamic line rating (DLR) models the transmission capacity of overhead lines as a function of ambient conditions. It takes advantage of the physical thermal property of overhead li…
Fast and Reliable Primary Frequency Reserves From Refrigerators with Decentralized Stochastic Control
Evangelos Vrettos, Charalampos Ziras, Göran Andersson
Due to increasing shares of renewable energy sources, more frequency reserves are required to maintain power system stability. In this paper, we present a decentralized control sch…
Corrective Control to Handle Forecast Uncertainty: A Chance Constrained Optimal Power Flow
Line Roald, Sidhant Misra, Thilo Krause +1
Higher shares of electricity generation from renewable energy sources and market liberalization is increasing uncertainty in power systems operation. At the same time, operation is…
