Distributed Power Generation Planning Considering Power Quality Requirements

Reasonable selection of the location and capacity of the distributed power generation can provide more power supply forms for the distribution network and reduce the investment in power grid. Therefore, a configuration planning method for distributed power generation is proposed considering the power quality requirements of the users. The user satisfaction index is introduced to measure the power quality requirements of sensitive users, and the effect of distributed power generation access on the voltage sag is fully exerted. On this basis, a configuration planning model is constructed by considering distributed power generation economy and user satisfaction. In order to improve accuracy and speed of the algorithm, the improved cuckoo algorithm is used to solve the model. Finally, the example is used to verify the effectiveness of the planning model. The research results can be used to guide the configuration planning of distributed power generation.
