摘要 为解决目前配电网中日益增加的新能源出力造成的功率波动问题,本文提出一种考虑时间和空间特性的平抑交直流混合配电网系统功率波动的最优储能配置方法。首先确立发电消纳及潮流、风机和光机等约束的数学模型,利用交替迭代法计算交直流混合配电网潮流,然后通过快速非支配排序遗传算法(NSGA-II)对模型进行求解,最后输出结果为最优解与其他可行解的优化指标对比图。通过储能系统优化配置,配电网偏差值与网络损耗都明显减小,验证了所提出的利用最优化储能系统配置平抑新能源发电并网产生波动方法的可行性。

Abstract:In order to solve the problem of power fluctuations caused by the increasing output of volatile new energy sources in the current distribution network, an optimal energy storage configuration method that considers the time and space characteristics of AC/DC hybrid distribution network system power fluctuations is proposed to stabilize the energy storage system. First, a mathematical model for power generation and consumption is established, as well as constraints such as power flow, wind turbines and optical machines, and the alternating iteration method is used to calculate the power flow of the AC/DC hybrid distribution network. Then the model is solved by the fast non-dominated sorting genetic algorithm, and the final output is the comparison chart of the optimization index of the optimal solution and other feasible solutions. Through the optimized configuration of the energy storage system, the deviation value of the distribution network and the network loss are significantly reduced, which verifies the feasibility of the method proposed in the article.
