摘　　要：全球气候变化加剧与能源需求增长推动了新能源微网在整合风能和太阳能等可再生能源方面的研究。然而,风能和太阳能的波动性带来了不确定性,影响了微网的经济效益和运行稳定性。针对这一问题,本文提出了一种考虑风光互补的新能源微网运行控制与仿真优化框架。首先构建了可再生能源优化配置模型,通过合理分配风能与光伏发电比例,提升能源利用效率和系统经济效益。随后,采用粒子群优化算法进一步优化风光互补效果。最后,通过仿真分析对优化框架的有效性进行验证。仿真结果表明,优化框架能在不同稳定性水平下有效降低电力交易成本,并显著减少资源潜力较低区域的平准化电力成本。在能源价格波动情况下,优化后的可再生能源组合仍保持较低的交换成本,展现出良好的适应性和经济效益。因此,电网公司可根据能源生产成本和实际风光互补性,灵活调整风光发电组合,实现经济目标的平衡。Increasing global climate change and growing energy demand have driven research into new energy microgrids for integrating renewable energy sources such as wind and solar.However,the volatility of wind and solar energy brings uncertainty,which affects the economic efficiency and operational stability of microgrids.To address this problem,this paper proposes a new energy microgrid operation control and simulation optimization framework based on the maximization of wind-solar complementarity,which firstly designs a method to optimize the combination of renewable energy sources,then adopts a particle swarm optimization algorithm to enhance the effect of wind-solar complementarity,and finally verifies the effectiveness of the framework through simulation.The simulation results show that the optimization framework can effectively reduce the energy exchange cost under different stability levels and significantly reduce the levelized cost of electricity in regions with low resource potential.Under energy price fluctuations,the optimized renewable energy portfolio still maintains a low exchange cost,demonstrating good adaptability and economic efficiency.Therefore,the grid company can flexibly adjust the wind and solar power generation portfolio according to the energy production cost and the actual wind and solar complementarity to realize the balance of economic objectives.
