Second, the intermittence and volatility of distributed generation will bring serious power quality problems to the distribution network
However, in the existing research, the optimal configuration method of the filter device is mainly concentrated on the traditional power distribution network, and there is less research on the optimal configuration of the active distribution network filter device; for the optimal configuration of the filter device, the active filter The filter is still the main filtering equipment, and the application of the hybrid active filter in the optimal configuration of the distribution network is still lacking.

Description
technical field [0001] The invention relates to a filter configuration method, in particular to a hybrid active filter position and capacity optimal configuration method in an active distribution network. Background technique [0002] With the increasingly prominent energy and environmental issues, distributed power generation technology has attracted more and more attention and applications due to its advantages of convenient installation, environmental protection, and flexible control. With the vigorous development of distributed generation, the traditional distribution network is gradually transitioning to the active distribution network. The application of active distribution network also creates conditions for the integration of distributed power generation into the grid, which is the future development trend of smart distribution network. The power quality and harmonic problems of the grid-connected power generation system have become the bottleneck restricting its de...
