摘要
风火电打捆是解决能源基地电力外送的有效手段。提出一种计及风速和负荷特性的风火电打捆发电系统优化规划方法。根据送端系统风速和受端系统负荷特性,建立打捆发电系统分段波动输送功率模型。以打捆发电系统在规划期内单位发电成本为优化目标函数,计及风电场拟规划区间约束和打捆发电系统运行约束,构建了风火电打捆发电系统优化规划模型。模型采用模拟退火算法求解,并通过算例分析证明所述方法的有效性。
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.
