Generation expansion planning considering thermal unit retrofit
The integration of large amounts of renewable energy has posed fundamental challenges to the operation and dispatch of the power system.A generation expansion model is proposed,in which thermal power,renewable energy,energy storage,and thermal unit retrofit are incorporated,with a unit commitment model to evaluate operation flexibility properly.The generation unit clustering technology is applied to improve the computation efficiency.Furthermore,the linearization of nonlinear function in the model intro-duces a mixed-integer linear programming formulation.The validity of the model is verified by provincial power grid in China.
