Enabling Efficient Scheduling of Multi-Type Sources in Power Systems via Uncertainty Monitoring and Nonlinear Constraint Processing.

As PV penetration increases, thermal power operating costs continue to decrease, reflecting the gradual weakening of system dependence on thermal units; meanwhile, hydropower deviation indices show an increasing trend, indicating that hydropower units undertake more regulation tasks; PV curtailment indices also gradually increase with penetration, reflecting more obvious PV output limitations under high penetration conditions. 4.4.
