Towards a Sustainable Microgrid on Alderney Island Using a Python-based Energy Planning Tool
Shahab Dehghan, Agnes M Nakiganda, James Lancaster +1
In remote or islanded communities, the use of microgrids (MGs) is necessary to ensure electrification and resilience of supply. However, even in small-scale systems, it is computat…
A Stochastic-Robust Approach for Resilient Microgrid Investment Planning Under Static and Transient Islanding Security Constraints
Agnes Marjorie Nakiganda, Shahab Dehghan, Uros Markovic +2
When planning the investment in Microgrids (MGs), usually static security constraints are included to ensure their resilience and ability to operate in islanded mode. However, unsc…
Active Distribution Grids Providing Voltage Support: The Swiss Case
Stavros Karagiannopoulos, Costas Mylonas, Petros Aristidou +1
The increasing installation of controllable Distributed Energy Resources (DERs) in Distribution Networks (DNs) opens up new opportunities for the provision of ancillary services to…
Improving Dynamic Performance of Low-Inertia Systems through Eigensensitivity Optimization
Ashwin Venkatraman, Uros Markovic, Dmitry Shchetinin +3
An increasing penetration of renewable generation has led to reduced levels of rotational inertia and damping in the system. The consequences are higher vulnerability to disturbanc…
Economic Valuation and Pricing of Inertia in Inverter-Dominated Power Systems
Matthieu Paturet, Uros Markovic, Stefanos Delikaraoglou +3
This paper studies the procurement and pricing of inertial response using a frequency-constrained unit commitment formulation, which co-optimizes the provision of energy and inerti…
Active Distribution Grids offering Ancillary Services in Islanded and Grid-connected Mode
Stavros Karagiannopoulos, Jannick Gallmann, Marina Gonzalez Vaya +2
Future active distribution grids (ADGs) will incorporate a plethora of Distributed Generators (DGs) and other Distributed Energy Resources (DERs), allowing them to provide ancillar…
Stochastic Unit Commitment in Low-Inertia Grids
Matthieu Paturet, Uros Markovic, Stefanos Delikaraoglou +3
In this paper, the Unit Commitment (UC) problem in a power network with low levels of rotational inertia is studied. Frequency-related constraints, namely the limitation on Rate-of…
Risk averse stochastic programming: time consistency and optimal stopping
Alois Pichler, Alexander Shapiro
Bellman formulated a vague principle for optimization over time, which characterizes optimal policies by stating that a decision maker should not regret previous decisions retrospe…
A hybrid approach for planning and operating active distribution grids
Stavros Karagiannopoulos, Petros Aristidou, Gabriela Hug
This paper investigates the planning and operational processes of modern distribution networks (DNs) hosting Distributed Energy Resources (DERs). While in the past the two aspects…
