This invention relates to the field of power engineering management and control and virtual power plant operation collaboration technology, specifically to a big data-based intelligent management and control system and method for power engineering. It collects and evaluates the quality of multi-source heterogeneous data from power engineering sites to obtain reliable data for engineering risk prediction, while simultaneously extracting feature data related to virtual power plant operation. Furthermore, it identifies and aggregates dispatchable load resources at the engineering site to form standardized virtual load packages. Combining the operational demand signals of the virtual power plant with the engineering risk status, it generates dispatch decision schemes through collaborative optimization calculations. Blockchain technology is used to ensure the reliable storage of dispatch instructions, execution, and result data, and based on this, automatically calculates collaborative benefits. This effectively solves the problem in existing technologies where power engineering management and control data are disconnected from virtual power plant operation, preventing a shift from passive risk warning to proactive value mining.
