The invention provides a distributed scheduling method for a thermoelectric coupling system. The method comprises the steps that S1, electrical loads of a distribution network is calculated accordingto electrical load consumption of a heat pump of a heat network; according to the electrical loads of the distribution network, optimal power flow of the distribution network is calculated, a runningstate of the distribution network is acquired and nodal price of the distribution network is updated; according to the nodal price of the distribution network, optimal power flow of the heat network is calculated, a running state of the heat network is acquired, and electrical load consumption of a heat pump of the heat network is updated; S2, step S1 is repeated, until a convergence error of therunning states of the distribution network and heat network is less than a preset error threshold and / or the running time of step S1 is greater than a preset time threshold, and the running states of the distribution network and heat network are applied to schedule the thermoelectric coupling system. According to the provided method, iteration is conducted on the basis of information exchange between the distribution network and the heat network, the internal optimization of the distribution network and heat network is achieved, the problem is solved that a centralized dispatching center does not exist in a reality system, and the scheduling calculation of the thermoelectric coupling system is simplified.
