This invention discloses a method and system for optimizing wind farm layout to balance noise and power generation. The method includes: establishing a multi-objective optimization model for wind farm layout; setting reference points and weight vectors based on decision preference information; and generating... N P A wind farm layout is used to form a parent population; the parent population is divided into several subpopulations and searched to generate mutation vectors; local difference operations are performed on the mutation vectors to obtain candidate layout solutions; based on the candidate layout solutions, a double substitution operation is performed on each target vector to generate a offspring population; the offspring population is merged with the parent population, and the optimal layout is selected. N P This invention involves repeatedly performing an optimization process on individual wind farms, outputting optimization results, and determining whether the decision-maker's preference information needs adjustment based on the optimization results. If not, it outputs the wind farm layout. This invention increases power generation while reducing wind farm noise, and can obtain a wind farm layout scheme that matches the decision-maker's preferences.
