Zero-energy-consumption building energy reserve optimization method and device and electronic equipment

The invention provides a zero-energy-consumption building energy reserve optimization method and device and electronic equipment, and the method comprises the steps: obtaining historical data of a zero-energy-consumption building energy system in a target time period, the historical data comprising a plurality of external environment parameters and target parameters of a zero-energy-consumption building, the target parameters at least comprise energy reserve parameters of multiple energy assemblies, establishing a multivariate nonlinear regression model between each target parameter and at least one external environment parameter, establishing a target function group of multi-target optimization based on the multivariate nonlinear regression model, and setting constraint conditions of the target function group; and solving the target function group by using an optimization algorithm to obtain an optimal parameter value of each target parameter, so that a non-linear relationship between the external environmen
