The invention belongs to the technical field of multi-energy utilization and particularly relates to a control method for "source-grid-load" coordinated optimization based on new energy accommodation,and the method is the control method for the source-grid-load coordinated optimization of the new energy accommodation. The method includes the following steps: taking an indicator of a power supplyside as an example, and performing normalization treatment on the index of the power supply side in a form of a matrix; screening energy storage devices that accommodates new energy to make energy storage units reach nearby equilibrium; calculating a work state matrix coefficient of source-grid-load: ensuring maximization of economic benefits as a principle, and establishing an objective functionF (X, Y, Z) based on economic indicators of the power supply side, a user side, and a power grid side; and according to a relationship of each of influence parameters, establishing an inner product space of relevant parameters,
