Grid Tariffs Based on Capacity Subscription: Multi Year Analysis on Metered Consumer Data
Sigurd Bjarghov, Hossein Farahmand, Gerard Doorman
While volume-based grid tariffs have been the norm for residential consumers, capacity-based tariffs will become more relevant with the increasing electrification of society. A fur…
Characterization of flexible electricity in power and energy markets
Güray Kara, Asgeir Tomasgard, Hossein Farahmand
The authors provide a comprehensive overview of flexibility characterization along the dimensions of time, spatiality, resource, and risk in power systems. These dimensions are dis…
Long-term Value of Flexibility from Flexible Assets in Building Operation
Kasper Emil Thorvaldsen, Magnus Korpås, Hossein Farahmand
In this work, we investigate how flexible assets within a residential building influence the long-term impact of operation. We use a measured-peak grid tariff (MPGT) that puts a co…
BATTPOWER Application: Large-Scale Integration of EVs in an Active Distribution Grid -- A Norwegian Case Study
Salman Zaferanlouei, Venkatachalam Lakshmanan, Sigurd Bjarghov +2
In this paper, we introduce an application of a high-performance MultiPeriod AC Optimal Power Flow (MPOPF) solver, called "BATTPOWER", to simulate active distribution grids for a n…
BATTPOWER Toolbox: Memory-Efficient and High-Performance Multi-Period AC Optimal Power Flow Solver
Salman Zaferanlouei, Hossein Farahmand, Vijay Venu Vadlamudi +1
With the introduction of massive renewable energy sources and storage devices, the traditional process of grid operation must be improved in order to be safe, reliable, fast respon…
Representing Long-term Impact of Residential Building Energy Management using Stochastic Dynamic Programming
Kasper Emil Thorvaldsen, Sigurd Bjarghov, Hossein Farahmand
Scheduling a residential building short-term to optimize the electricity bill can be difficult with the inclusion of capacity-based grid tariffs. Scheduling the building based on a…
Hydrothermal Scheduling in the Continuous-Time Framework
Christian Øyn Naversen, Arild Helseth, Bosong Li +3
Continuous-time optimization models have successfully been used to capture the impact of ramping limitations in power systems. In this paper, the continuous-time framework is adapt…
A Three-Stage Stochastic Peer-to-Peer Market Clearing Model with Real-Time Reserve Activation
Sigurd Bjarghov, Christian Ø. Naversen, Kasper Thorvaldsen +1
With an increasing share of volatile renewables, more flexibility is needed to balance the electricity system. In order to enable local flexibility, we suggest a three-stage stocha…
Procurement of Spinning Reserve Capacity in aHydropower Dominated System Through MixedStochastic-Robust Optimization
Christian Øyn Naversen, Hossein Farahmand, Arild Helseth
As the penetration of variable renewable powergeneration increases in power systems around the world, systemsecurity is challenged. Ensuring that enough reserve capacity isavailabl…
