The invention discloses an electrical integrated energy system scheduling method based on an information gap decision theory. The method comprises the following steps: establishing an information gapdecision theory model; building an optimal economic benefit operation model is formed after a wind power-pumped storage unit is combined; considering wind power output uncertainty, and establishing awind storage combined unit scheduling model based on an information gap decision theory; establishing a determined electrical integrated energy system scheduling model; considering the uncertainty ofthe load, and establishing an electrical integrated energy system scheduling model based on an information gap decision theory; solving the model in combination with a bacterial population drug tendency algorithm; and sending the solving result to an energy scheduling center, and scheduling the energy system by the energy scheduling center according to the solving result. The scheduling strategy provided by the invention can effectively reduce the intermittency and volatility of wind power, improve the wind power consumption, increase the economic benefits of an electrical integrated energy system, and provide different scheduling strategies for decision makers with different risk preferences.
