In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as voltages, voltage angles, real power and reactive power. It analyzes the power systems in normal steady-state operation.

This invention relates to the field of energy management technology, specifically disclosing a power supply and demand balance optimization system based on source-grid-load coordination. The system includes a data acquisition and prediction module, which acquires data from the distribution network and the external environment, and outputs prediction curves and confidence intervals; a power flow feasible region construction module, which generates a power flow feasible region based on the prediction curves and confidence intervals, and outputs a time-based constraint set; and a multi-time-scale rolling optimization module, which, within the power flow feasible region, simultaneously solves the time-based constraint set and uses a feasible region projection time-series scheduling algorithm for online rolling optimization; when the voltage proximity index is detected to exceed a preset threshold, a short-window re-optimization is initiated to optimize the power supply and demand balance. This invention satisfies network security and power supply and demand balance in distribution network scenarios with high penetration of distributed energy and coexisting uncertainties.
