【摘要】：针对废旧地下矿井极易造成地表塌陷、水土流失的问题,提出将井下相应区域改造成抽水蓄能电站,进而与风-光互补系统结合,建立风-光-抽水蓄能联合互补发电系统。以跟踪负荷曲线和系统出力波动性最小为优化目标,分别对风力发电、光伏发电和抽水蓄能电站建立出力数学模型,并在考虑风-光互补特性、电网传输功率等约束条件下,利用改进粒子群算法对模型进行求解。算例仿真结果验证了所建模型可以很好地跟踪优化目标,有效解决了新能源并网时的功率波动和消纳问题。
[Abstract]:In view of the problem of surface collapse and soil erosion caused by waste underground mines, it is proposed that the corresponding underground areas be transformed into pumped storage power stations, and then combined with the air-optic complementary system to establish a combined air-optical-pumped storage power generation system.In order to track the load curve and minimize the system output fluctuation, the mathematical models of wind power generation, photovoltaic power generation and pumped storage power station are established respectively, and the constraints of wind and optical complementarity and transmission power are taken into account.The improved particle swarm optimization algorithm is used to solve the model.The simulation results show that the proposed model can track the optimization target well and solve the problem of power fluctuation and absorption effectively when new energy is connected to the grid.
