Abstract: An algorithm based on power flow principles has been devised to enhance generator voltage settings and compensation parameters, thus maintaining equilibrium in current magnitudes across distinct cable lines (CLs). The proposed operational framework is designed to reduce Joule losses while concurrently enhancing the efficiency of cable lines. Moreover, it adheres to network code stipulations regarding reactive power exchanges with the overarching bulk power system. The operational effectiveness of the framework is showcased through a theoretical exploration of a 199 km, 400 kV-50 Hz cable system, which can aggregate up to 2 GW from multiple offshore wind power plants. The data demonstrates that the proposed approach consistently reaches a transmission efficiency of at least 97% in maximum load situations, with generator power factors tending towards unity. The methodology employs variable shunt compensation to dynamically respond to fluctuations in load and enhance voltage stability throughout the system. Furthermore, the methodology demonstrates a high degree of flexibility, accommodating the dynamic nature of renewable energy integration scenarios while ensuring compliance with contemporary grid standards. However, the analysis reveals a potential obstacle associated with the increase in sending-end voltage during full load conditions, thereby highlighting the imperative for comprehensive voltage management protocols at the network connection point. Further research could examine real-world applications to validate the theoretical conclusions and assess the scalability of the framework within diverse working environments.
