The invention relates to the technical field of natural gas peak shaving operation, in particular to a comprehensive evaluation method for peak shaving schemes of a gas pipe network and a gas storage. The method comprises the steps of 1, predicting a city gas load: building a city gas load prediction model by adopting an artificial neural network model, and predicting the city gas load subjected to peak shaving by using a differential evolution extreme learning machine algorithm, thereby determining a peak shaving quantity; 2, performing peak shaving optimization on the gas storage: according to previous peak shaving operation experience of the gas storage, fitting out a relational expression of operation parameters of the gas storage and the peak shaving quantity, and obtaining a gas recovery rate of the gas storage under a certain peak shaving quantity; 3, simulating a peak shaving quantity of the pipe network, and obtaining preselected peak shaving schemes; and 4, comprehensively evaluating the peak shavin
