An MILP Approach Based Optimization Techniques for Offshore Wind Farms Electrical Collector Systems

The sizing and placement of the lines between the offshore substation (OS) and the wind turbines (WTs) are optimized using the mixed integer linear programming-based approach to large-scale offshore wind farm collector system planning (OWF-CSP) that we offer in this work. In order to guarantee the radiality of the topology of the offshore wind farm's collector system and expedite the solution process, we discover that the problem is comparable to distribution system planning, where topological constraints from Distribution Network Extension Planning (DNEP) are implemented. The effectiveness of the proposed method is demonstrated by a case study based on an OWF with 42 fixed-location WTs. The OWF-CSP approach suggested in this paper reduces the computational time with the aid of radiality constraints and lowers the investment cost and power loss on the cables in comparison to the conventional design.
