The development of bundled wind-thermal generation systems(BWTGSs)is an effective way to transmit the power generated by energy bases.A method for the optimal planning of BWTGSs is proposed.By taking the wind speed of wind farm and the load characteristics of the receiving power system into account,a sectionalized and range-fluctuated power transmission model is formulated.By using the unit generation cost of BWTGS in the planning time frame as the objective function,planned capacity range of wind power and operation restrictions of the bundled system as the constraints,an optimal planning model is developed.The simulated annealing algorithm is employed to solve the model and numerical test verifies the effectiveness of the proposed method.
