摘　　要：为兼顾微电网的稳定性和运行效益,分析了构网型储能的惯量支撑特性和频率支撑能力。基于此,明确了微电网的优化目标,形成了功率平衡、设备运行、系统惯量、系统备用容量等约束,并结合Optimization Toolbox的非线性优化问题解算器,提出了考虑构网型储能支撑能力的优化调度策略。为测试所提策略的有效性,采用核密度估计法和Copula函数构建了风光出力联合概率分布函数,基于K-means聚类形成新能源典型场景。在典型场景下进行分析,结果表明:所提方法能够发挥构网型储能支撑能力,有效提升新能源消纳水平。In order to coordinate the stability and operation efficiency of the microgrid,the inertial support characteristics and frequency support capability of the grid-forming storage are analyzed.Based on this,the optimization objectives of the microgrid are clarified,and the constraints such as power balance,equipment operation,system inertia,and reserve capacity are formed.Combined with the nonlinear optimization problem solver of the Optimization Toolbox,an optimization scheduling strategy considering the support capability of the grid-forming energy storage proposed.In order to test the effectiveness of the proposed strategy,the joint probability distribution function of wind and solar power generation is constructed by using the kernel density estimation method the Copula function,and the typical scenarios of new energy are formed based on the K-means clustering.The analysis is carried out under the typical scenarios,and results show that the proposed method can give full play to the support capability of the grid-forming energy storage and effectively improve the level of new energy consumption.
