Title: ELECTRIC REACTIVE POWER OPTIMIZATION SYSTEM AND METHOD BASED ON DOUBLE FISH-SWARM ALGORITHM
Abstract:
Provided in the present invention are an electric reactive power optimization system and method based on a double fish-swarm algorithm. The system comprises: a grid status acquisition module, a grid reactive power regulation module, and a grid reactive power execution module. The grid status acquisition module comprises a grid status acquisition device and a relay transmitter. The grid reactive power regulation module is a control terminal. The grid reactive power execution module comprises generator terminal voltage regulators, transformer tap regulators, and reactive power compensation regulators. The method comprises: acquiring initial data to be optimized of a current network; optimizing the initial data to be optimized of the current network based on a double fish-swarm algorithm to obtain optimized values of control variables in the grid; and the grid reactive power execution module regulating, according to the obtained optimized values of the control variables in the grid, generator terminal voltages, transformer taps, and compensation capacities of reactive power compensators. The method of the present invention can effectively enhance an optimizing ability of a grid in terms of reactive power optimization, and render the reactive power flow distribution of the power distribution network to be optimized more rationally.
