Optimal reactive power control based on bidding strategy in district power grid

The suboptimal control by expert system is the backup protection of online optimal reactive power control in district power grid. Since the logic of expert system software designed according to the traditional production rules is complicated,a decision model of optimal reactive power control is established based on the bidding strategy and an evaluation model of voltage reactive power optimization is built based on the comprehensive bid evaluation method. A framework based on the multi-Agent system is established for the optimal reactive power control of district power grid,which realizes the bidding strategy by the parallel and coordinated control among multiple Agents to ensure its robustness,maintainability and expandability. The practical application verifies its effectiveness.
