[0037] Step S100, establishing an energy system economic scheduling linear programming mathematical model;

[0038] In some implementations, mathematical models are typically generated using elements to connect nodes to establish relationships between different degrees of freedom, however, sometimes it is necessary to be able to characterize special details (hinge connections of rigid domain structures, symmetric sliding boundaries, periodic conditions, and other special internal node connections, etc.). These are expressed in terms of unit insufficiency. Coupling and constraint equations can be used to establish special connections between nodal degrees of freedom, and these techniques can be used to connect degrees of freedom that ele...
