Sustainable low emission offshore oil and gas platforms (OOGPs) are expected to comprise a lower number of gas turbine generators (GTGs) and offshore wind turbines integrated with battery energy storage systems (BESS). This combination faces challenges with the traditional platform loads, i.e. heavy induction motors (IMs), that are started directly on-line. They draw high inrush currents resulting in voltage sags affecting other loads connected to the common bus. These sags could activate a Low-voltage ride-through control scheme on wind turbines (WTs) and dissipate the generated wind power into a dynamic brake resistor (DBR) while regulating the grid voltage. Improper control coordination of the GTGs, WTs, and BESS could either fail or delay the motor start-up, with a detrimental impact on the industrial process. Considering the above, this paper proposes a Cooperative Control (CoC) strategy of BESS, WTs, and GTGs for the efficient starting of heavy motors with reduced loss of generated wind power. The proposed control strategy is simulated utilizing MATLAB for a real industrial scenario, and the results are discussed.
