随着"双碳"目标的推进和分布式新能源的快速发展,电网面临着巨大的挑战.为了平衡电动汽车的波动性和新能源出力的随机性,缓解弃风弃光和大规模电动汽车入网对电网造成的冲击,采用蒙特卡洛法模拟电动汽车入网数据,同时结合电动汽车负荷转移策略对微电网进行优化配置,建立以年等值收益为优化目标的微电网优化配置模型,并评估配置结果.通过采用场景缩减法和改进粒子群算法求解模型.算例结果证明了优化配置模型的合理性和经济性.
Optimized Configuration of Microgrid Capacity Considering Electric Vehicle Load
With the promotion of the goals of"Carbon Peaking and Carbon Neutrality"and the rapid development of distributed new energy,the power grid is facing enormous challenges.In order to balance the volatility of electric vehicles and the randomness of new energy output,alleviate the impact of wind and solar power abandonment and large-scale electric vehicle integration on the power grid,Monte Carlo method was used to simulate the data of electric vehicle integration.At the same time,combined with the electric vehicle load transfer strategy,the microgrid was optimized and configured,and a microgrid optimization configuration model with annual equivalent income as the optimization goal was established,and the configuration results were evaluated.The model was solved by using scene reduction method and improved particle swarm optimization algorithm.The example results demonstrate the rationality and economy of the optimized configuration model.
