The invention discloses a distribution network
tail end
low voltage comprehensive treatment method and
system, and relates to the technical field of
power electronics, precise treatment is realized through six steps: firstly, collecting various operating parameters such as three-phase
voltage, load power and the like, and adopting a combined model fusing LSTM and grey prediction to adaptively adjust an output proportion and improve parameter prediction precision through a dynamic weight; a three-dimensional fuzzy evaluation matrix is constructed based on the
voltage deviation, the load fluctuation coefficient and the DG output randomness, and risk grading is realized; then constructing a multi-objective optimization model with a dynamic weight, and synchronously setting multiple constraint conditions; solving an
optimal treatment parameter by adopting an improved
particle swarm algorithm introducing
chaotic disturbance; governance is executed according to the parameters, and the prediction model is corrected through an
exponential smoothing method; and finally, calculating a comprehensive benefit index, and dynamically adjusting and optimizing the weight of the model. The
system comprises nine modules including a
data acquisition module, a combined prediction module, a risk grading module and the like, and closed-
loop optimization is formed. The method and
system can significantly improve the
voltage qualified rate, reduce the network loss and compensation cost, adapt to a complex distribution network scene, and provide double guarantees for the reliability and economy of power supply.
