Embodiment Construction
[0098] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0099] Taking the IEEE30 system as an example, the IEEE30 node system is used for testing. The system has 30 nodes, 37 transmission lines, 4 transformers, 6 generating units, and 2 load nodes equipped with capacitive reactive power compensation. The voltage of the PV node and the balance node is set to 0.90-1.10, the voltage of the PQ node is set to 0.95-1.05, and the variable ratio range of the adjustable transformer is 0.90-1.10. The wiring diagram of the IEEE30 node system is as follows figure 1 shown. The following is a specific description of the algorithm steps for solving the multi-objective reactive power optimization based on the power coefficient weighting method by using the original dual interior point method:
[0100] The first step is to set the system parameters of the algorithm program. The number of system nodes is 30, the number o...
