The invention discloses a set of pump station control methods considering startup and shutdown loss based on a linear integer-dynamic programming combination algorithm, and belongs to the technical field of optimization scheduling. The method includes the following steps: step 1) establishing a model: establishing a model which takes the minimum total power consumption cost of startup operation as a target function, takes two or three of startup and shutdown variables, a blade setting angle and a water pump rotating speed in each time period as decision variables, and simultaneously needs to meet a total water lifting amount constraint and a motor rated power constraint in a specified time period; (2) solving the model, specifically, wherein the model is optimized and solved through a linear integer-dynamic programming combined algorithm, a theoretical optimal value is obtained, and result information is output and comprises the time-average lift, the startup and shutdown states of different time periods, the
