The invention relates to a multi-source coupled integrated energy system planning method. The method comprises steps that 1), an integrated energy system coupling model is established, and the coupling relationship among cold/heat/electrical/gas energy forms is described through listing mathematics coupling matrixes; 2), regional present situation analysis is carried out; 3), regional energy demand prediction is carried out; 4), energy supply equipment output analysis is carried out; and 5), energy station site selection and capacity setting are carried out, energy station site selection is reasonably determined, an energy station optimization planning target function and a constraint condition establishment solving model are determined, and the optimal energy station configuration capacity is acquired through solving the model. The method is advantaged in that on the condition that cold/heat load demands can be satisfied, site selection and capacity setting of a wind turbine generatorsystem, a photovoltaic electrical station, a gas turbine set and a ground source heat pump set are optimized, and bases are provided for planning and operation of an integrated energy system.
