Embodiment Construction
[0048] The reactive power optimization method of the power system proposed by the present invention, which takes into account both the correction of voltage over-limit and the reduction of system active power loss
[0049] Combined embodiment is described in detail as follows:
[0050] The reactive power optimization method of the power system proposed by the present invention, which takes into account both correction of voltage over-limit and reduction of system active power loss, includes the following steps:
[0051] 1) Collect the current real-time measurement data of the power grid, and obtain the base state value of the current power grid operation state through state estimation and power flow calculation: set the base state voltage amplitude of the i-th node as V i , its upper voltage limit is The lower voltage limit is and (from the quarterly voltage operation curve formulated by the operator); for the generators participating in the reactive power optimization of...
