Embodiment Construction
[0051]A two-stage continuous discrete reactive power heuristic optimization method with embedded Benders decomposition. For the optimization of traditional secondary voltage control, Benders decomposition and two-stage heuristic algorithm are used to coordinate continuous and discrete reactive power sources in the region. The specific steps are as follows :
[0052] Step 1: Partition voltage control is based on the locality of reactive power and voltage, select several buses and reactive power equipment to build control partitions, calculate the sensitivity of reactive voltage control in the control partition, and establish a mathematical optimization model for secondary voltage control, specifically expressed as follows :
[0053]
[0054] The meaning of the above mathematical model is as follows:
[0055] 3) The control variable is the reactive power output of the power plant generator ΔQ g , Substation low-voltage side capacitors, reactor reactive output ΔQ c , C pg ...
