Secondary and Tertiary Voltage Regulation Controls Based on Regional Optimal Power Flows

摘要: This paper proposes a combined Secondary and Tertiary Voltage Regulation (SVR+ TVR) methodology based on regional optimal power flows (OPFs) to periodically update the generators' voltage regulator set points. The OPFs' objective is minimize active losses (MAPL) in system. presented technique compared with respect conventional SVR distributed control approach, where pilot-bus points are determined by using centralize TVR approach MAPL. Time domain simulations of New England 10-machine 39-bus test system an equivalent Mexican interconnected used validate proposed SVR+T VR technique, demonstrate its advantages existing approaches.
