要約(日本語): High penetration of renewable energy in the future power system will pose a big problem to the load dispatch operation. The large disturbance and high forecast error must be considered when scheduling a limited number of controllable generators to follow rapid change in load. This paper proposes dynamic economic load dispatch (DELD) problem approach based on the concept of feasible operation region (FOR). FOR is defined as the region that committed generators may operate to match the load profile without violating the ramp-rate constraints. The DELD problem is solved in two stages. In the first stage, FOR of each generator is computed using recent real-time forecasted load as well as renewable energy generation. In the second stage, a generation schedule is determined by solving the DELD problem interval by interval while considering ramp-rate constraints and FOR constraints. The method can gives feasible solution for feasible load and specify the amount of compensation required for feasible solution for infeasible load.
