A multi-type photo-thermal power station coordinated dispatching operation method responding to power grid demands relates to the technical field of photo-thermal power station dispatching, and comprises the following steps: step 1, collecting and processing power generation data characteristics of photovoltaic power stations in Qinghai region, and carrying out statistical analysis; 2, analyzing energy storage system optimization configuration of the off-grid independent photovoltaic power station based on a spectrum analysis method; 3, constructing a hybrid energy storage ordered charging and discharging strategy by using ultra-short-term photovoltaic power prediction information, and further constructing an optimal control model by taking the minimum charge offset as a target and the charging and discharging power and capacity as constraints to obtain a dynamic stabilizing method for photovoltaic power fluctuation of prediction control step length; and 4, on the basis of the photovoltaic power fluctuation d
