Abstract：In hydro-wind-thermal hybrid power system, the peaking of hydro generators is valuable. In this paper, an economic dispatch model for hydro-wind-thermal hybrid system is proposed, which is modeled as a mixed integer linear programming(MILP)problem and therefore can be efficiently solved by using GAMS. The peaking value of generators is quantified by using the proposed economic dispatch model. Based on Shaley value and peaking mileage concepts, two peaking cost compensation methods are proposed. The effectiveness of the proposed methods is shown with the simulation results of a 5-generator 8-bus power system.
