The invention relates to the technical field of power supply and demand prediction, and discloses a power supply and demand prediction method suitable for a complex market environment. The method comprises the following steps: collecting multi-dimensional real-
time data of a
power market, wherein the multi-dimensional real-
time data covers a user-side load fluctuation sequence and a market
electricity price fluctuation signal; constructing a power supply and demand
dynamic prediction model based on the data, and outputting a theoretical supply and demand prediction value; comparing the theoretical predicted value with the actual measurement
electric power data, carrying out multi-dimensional
difference analysis containing load sequence deviation
response delay, and generating a market-level difference
coefficient matrix; inputting the matrix into a regional energy
network analysis model, generating a supply and demand abnormal propagation path probability
distribution diagram and positioning a
potential market imbalance region in combination with
power grid node transmission capability and economic main body distribution information; and a prediction adjustment strategy is adaptively configured according to the probability
distribution diagram, high-
frequency data monitoring is started for a high-probability imbalance area, policy disturbance testing is applied to an associated market subject, and stable operation of the
power market is supported.
