Hafiz, Student Member, IEEE, Yutaka Sasaki, Member, IEEE, and Yoshifumi Zoka, Member, IEEE Abstract—A large amount of renewable energy penetration horizon using future load forecast to determine the economic may cause a serious problem in load dispatch in the future power allocation of generation to the load [1]. It also takes into ac- system, where the amount of controllable generators will decrease count the dynamic constraints of generators such as dynamic while disturbances increase. Therefore, a new economic load dispatch (ELD) method is required in order to make the best use ramp-rate in the optimization process [2]. The heuristic tech- of the ramp-rate capability of existing generators to cope with nique developed in [3] is useful because of its simplicity even the disturbances caused by loads as well as by renewable energy though not necessarily optimal. References [4] and [5] use the generations. This paper proposes a new dynamic ELD method to simulated annealing in the DELD problem. Hybrid algorithm meet the general requirements for real-time use in a future power was proposed in [6] consisting the Hopfield neural network and system, where load following capability is critically limited. The method is also satisfactory from an economical point of view, and quadratic programming (QP). A price-based ramp-rate model is suitable for high-speed online application due to fast and steady has been proposed in [7] for application
