Discussion on Voltage Optimization Control in Heyuan Power System

Aiming at voltage overshoot of Heyuan power system in high water period,minimum network loss,minimum voltage deviation as well as their combination are targeted,primal-dual interior point algorithm and load-flow optimization are adopted.By adjusting tapping of main transformers,shunt reactive compensation devices and output power,optimization control of grid voltage and loss are achieved in consideration of indexes of load margin.The application of this optimization method in Heyuan power system greatly improves voltage quality and reduces grid loss in the region,which proves its practicability and feasibility.
