To further save the energy and reduce the system power generation cost

a real-time generation scheduling model is proposed. In this model

different models and different distribution strategies for the positive and negative power deviations generated by unit power output regulation can be adopted. The piecewise regulation cost of unit power regulation is introduced

then the different control and distribution strategies can be realized by setting different regulation costs. An actual provincial power system in China is tested. The results show that the model can adjust the unit power in a rational way according to the planned principle

and well track the day-ahead schedule. The model also satisfies the limit values of network constraints.
