交直流混合配电网是主动配电网的重要分支,其灵活性运行域研究对实现输-配电网主动交互及高效经济调度具有重要意义。计及光伏、储能及可控负荷的灵活运行特性,文中构建了基于DistFlow潮流模型的交直流混合配电网功率灵活性运行域模型。首先,为降低光伏出力随机性的影响,采用多个典型场景下运行域的交集作为交直流混合配电网的灵活性运行域,并采用椭圆对多个连续时段的交流侧根节点有功功率-无功功率、电压源型换流器(VSC)交互有功功率的运行域进行近似。其次,通过添加外近似多边形顶点约束将模型转化为单层优化模型求解,在最大化椭圆面积的同时保证其分解可行性。最后,采用33节点和93节点交直流混合配电网为算例进行分析,研究了储能、可控负荷、VSC控制方式以及不同光伏渗透率对功率灵活性运行域的影响,采用蒙特卡洛方法验证了椭圆灵活性运行域的分解可行性,并在求解速度和精度上与传统方法进行了对比。
The AC/DC hybrid distribution network is an important branch of the active distribution network
and the research on its flexibility operation region is of great significance to realize the active interaction of transmission and distribution networks and efficient and economic dispatch. Considering the flexibility operation characteristics of photovoltaic
energy storage and controllable load
a power flexibility operation region model of AC/DC hybrid distribution network based on DistFlow power flow model is constructed. Firstly
in order to reduce the influence of the randomness of photovoltaic output
the intersection of the operation regions in multiple typical scenarios is used as the flexibility operation region of the AC/DC hybrid distribution network
and the ellipses are used to approximate operation regions of active-reactive power of root nodes at the AC side and the interactive active power of the voltage source converter (VSC) for multiple consecutive periods. Secondly
the model is transformed into a single-layer optimization model by adding outer approximate polygon vertex constraints to maximize the area of the ellipse while ensuring the feasibility of its decomposition. Finally
the 33-node and 93-node AC/DC hybrid distribution networks are used as examples for analysis
and the influence of energy storage
controllable load
VSC control mode and different photovoltaic penetration rates on the power flexibility operation region is studied. The Monte Carlo method is used to verify the decomposition feasibility of the ellipse flexibility operation region
and the solution speed and accuracy are compared with the traditional method.
