In this paper

an optimal distributed control strategy of active power of wind turbine generators was proposed. Based on this strategy

a development scheme of optimal distributed control system was proposed. In the scheme

the system was set up between the automatic generation control (AGC) system of wind farm and the energy management system (EMS) of wind turbine generators

and the original framework of AGC system and EMS would not been changed. For the purpose to effective employ the facility with high price of electricity and stability

the system can achieve the optimal distributed controlling of active power of wind turbine generators

by considering the factors of group of wind turbine generators

such as price of electricity

stability of facility

power generation capacity and facility life.
