Case Study of Integrating an Offshore Wind Farm with Offshore Oil and Gas Platforms and with an Onshore Electrical Grid

Table 1

Three study cases.

Cases description	Objectives
Case 1 —20 MW wind farm: Four 5 MW wind turbines generate electrical power in parallel with three gas turbines (each has capacity of 23 MW)	(i) Estimate the long-term operation benefits of wind power integration in terms of fuel savings and CO2/NO𝑥 emissions reduction.; (ii) Determine the electrical grid stability due to the integration of four 5 MW wind power generator units.; (iii) Identify the maximum amount of wind power possible to integrate to the stand-alone electrical grid on the offshore platform.
Case 2 —100 MW wind farm: 20 units of 5 MW wind turbine are connected to five nearby platforms	(i) Assess the maximum amount of wind power that can be integrated to each platform.; (ii) Electrical grid stability in terms of the control strategy and interconnecting grid topology.
Case 3 —1000 MW wind farm: 200 units of 5 MW wind turbine are both connected to platforms and to the onshore electrical grid	(i) Design the electrical grid layout.; (ii) Calculate the transmission losses.; (iii) Evaluate the electrical grid stability.
