Optimal Grid Layouts for Hybrid Offshore Assets in the North Sea under Different Market Designs

no code implementations3 Jan 2023 Stephen Hardy, Andreas Themelis, Kaoru Yamamoto, Hakan Ergun, Dirk Van Hertem

To this end a multi-period, stochastic GATE planning formulation is developed for both nodal and zonal market designs.

Unbalanced OPF Modelling for Mixed Monopolar and Bipolar HVDC Grid Configurations

no code implementations11 Nov 2022 Chandra Kant Jat, Jay Dave, Dirk Van Hertem, Hakan Ergun

Bipolar HVDC grids can be operated in an unbalanced way during single pole outages or in form of mixed monopolar and bipolar grids.

Perspectives on distribution network flexible and curtailable resource activation and needs assessment

no code implementations21 Jul 2022 Md Umar Hashmi, Arpan Koirala, Hakan Ergun, Dirk Van Hertem

{A curtailable and flexible resource activation framework for solving distribution network (DN) voltage and thermal congestions is used to quantify three important aspects with respect to modelling low voltage networks.}

Chance constrained day-ahead robust flexibility needs assessment for low voltage distribution network

no code implementations21 Jul 2022 Md Umar Hashmi, Arpan Koirala, Hakan Ergun, Dirk Van Hertem

A framework is required to avoid over or under procurement of flexibility in the presence of uncertainty.

Flexible and curtailable resource activation in three-phase unbalanced distribution networks

no code implementations16 May 2022 Md Umar Hashmi, Arpan Koirala, Hakan Ergun, Dirk Van Hertem

In this work, we propose a network-state driven framework that distribution system operators (DSOs) can utilize for activating flexible and curtailable resources for alleviating network voltage and thermal issues, while accounting for network voltage and current imbalances.

Congestion Mitigation in Unbalanced Residential Networks with OPF-based Demand Management

no code implementations20 Apr 2022 Marta Vanin, Tom Van Acker, Hakan Ergun, Reinhilde D'hulst, Koen Vanthournout, Dirk Van Hertem

From a planning perspective, the results can help the system operator define contractual terms that make a specific congestion mitigation scheme effective and viable.

Evaluation of voltage magnitude based unbalance metric for low voltage distribution networks

no code implementations19 Feb 2022 Md Umar Hashmi, Arpan Koirala, Rickard Lundholm, Hakan Ergun, Dirk Van Hertem

We observe that phase magnitude-based unbalance metrics reasonably approximate the true unbalance for higher R/X ratios with a varying load power factor in a DN.
