Method for determining day declaration plan of virtual power plant and related device

The invention discloses a method for determining a virtual power plant day declaration plan and a related device. The method comprises the following steps: constructing a process name of a virtual power plant; performing an initialization process on internal control parameters of the intra-day rolling optimization algorithm; executing a cyclic calculation process of optimal scheduling; obtaining intra-day prediction data and a day-ahead scheduling plan; constructing a user model based on the intra-day prediction data and the day-ahead scheduling plan; constructing an optimization target and a constraint function based on the user model; calling the optimization solver to solve the constraint function to obtain a result before output; checking the result before output to obtain a final result; judging whether the intraday execution deviation value is out of limit or not; if the intra-day execution deviation value is out of limit, outputting an intra-day rolling plan value; and if the intra-day execution deviat
