Implementation of dynamic reactive power coordination control strategy based on AVC-SCADA system

Considering the defect of fixed on-off reactor group compensation in AVC system, this paper proposes a coordinated control strategy between virtual air-gap magnetized reactor (MCR SVC reactive power compensator) and AVC system of urban regional power grid. Combined with voltage and reactive power control strategy, a reactive power optimization model with minimum active network loss as objective function is established. It gives full play to the advantages of MCR type SVC reactive power compensator in continuous smooth adjustment of reactive power, and takes IEEE-14 example to carry out co-simulation analysis with PSCAD and MATLAB platform. The results show that dynamic adjustment can effectively reduce the active power loss of the system
