Problems solved by technology

[0004] 1) Low readability, poor scalability, not conducive to operation

At present, power companies in various countries have already promoted or are promoting the common information model (Common Information Model, CIM) standard based on IEC 61970 for scheduling and operation. The CIM is defined by RDF / XML, and the existing two-dimensional table model is difficult to adapt to it.

[0005] 2) The program internally uses global or static variables to store system state information, and there is thread competition in a multi-threaded environment. To solve this problem, cumbersome locks or synchronization operations are required, and the amount of data exchange is large in a distributed computing resource environment. Intermediate state is difficult to save

The above shortcomings make it difficult for existing power system simulation models and algorithms to adapt to multi-core and distributed computing platforms
