A large amount of renewable energy penetration may cause a serious problem in load dispatch in the future power system, where the amount of controllable generators will decrease while disturbances increase. Therefore, a new economic load dispatch (ELD) method is required in order to make the best use of the ramp-rate capability of existing generators to cope with the disturbances caused by loads as...
As more and more variable resources and demand response resources being integrated in the electric grid, the grid operation is experiencing increasing level of uncertainties.
