The invention discloses a distributed top pressure power generation system and a regulation and control method on the basis of a multi-objective optimization algorithm. According to the characteristics of input end working medium parameters (such as flow, temperature, pressure difference) and changeable output end load demand and difficult prediction of the distributed top pressure power generation system, the high system output stability, the high running efficiency and the long equipment service life are the objectives, a multi-objective optimization model of the distributed top pressure power generation system is established, the opening degrees of all valves in the system are solved in real time through a non-domination ranking genetic algorithm, and thus the system running efficiencyis improved. Through the multi-objective optimization algorithm, the opening degrees of all electric adjusting valves in the system can be optimized in real time according to change of parameters of the energy supply side and the energy using side, thus the purposes of improving the stability of the distributed top pressure power generation system, prolonging the equipment service life, improvingthe running efficiency and the improving the economic benefits are achieved, and the wide commercialized application prospects are achieved.
