Multi-objective optimal scheduling for hydro-thermal-wind power system

This paper focus on the multi-objective optimized scheduling for power system composed of thermal power, hydro power and wind power. According to the characteristics of hydro-thermal-wind power system, a multi-objective model is proposed with the objective to optimize the system operation cost, pollutant emission of thermal power and the net loss of power system, taking the operation constraints of each type power generator and the security requirements of the whole system into consideration. The pareto front of this multi-objective problem can be get by using CPLEX12.4. The validity of the proposed model is proved in IEEE 39-bus system. Also, some practical operation strategies for hydro-thermal-wind power system are proposed based on the pareto front.
