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 problems that waste mine can easily cause surface subsidence and soil erosion, the paper proposed to transform corresponding underground area into pumped-storage power station, and then combined with wind-light complementary system to establish wind-light-pumped-storage combined complementary power generation system. Tracking load curve and minimizing system output volatility are taken as the optimization target to establish output mathematical models of wind power generation, photovoltaic power generation and pumped-storage power stations. Improved particle swarm optimization algorithm is used to solve the models under the constraint condition of considering wind-light complementary characteristics and power transmission power. The simulation results show that the models can be used to track the optimization target, and effectively solve the problem of power fluctuation and consumption when the new energy is connected.
