The invention discloses a load dynamic sensing-based real-time load control decision-making platform and a load dynamic sensing-based real-time load control decision-making method. The real-time load control decision-making platform includes a real-time load dynamic sensing module, a load control decision-making module, a load decision-making response module and a control result feedback module which carry out information interaction with one another through a message bus. The decision-making method includes the following steps that: the real-time load dynamic sensing module carries out user automatic grouping and calculates real-time load and switchable load; the load control decision-making module analyzes issued decision-making instructions and outputs switchable users and the switchable load of the switchable users as load control instructions, wherein the switchable users are decided in advance; the load decision-making response module executes the load control instructions and calculates the switched-out quantity of the load; and the control result feedback module feeds back control execution results and the switched-out quantity of the load. With the load dynamic sensing-based real-time load control decision-making platform and method of the invention adopted, emergency processing speed be increased to a millisecond level, the interruptible load of users can be accurately controlled; and negative influences can be decreased to the largest extent.
