为应对含高比例光储的交直流混合配电网的统一建模和协同计算问题,构建了基于图计算的交直流混合配电网优化调度模型。首先,将交直流混合配电网中的设备抽象为图的顶点,建立了面向对象的交直流混合配电网图模型。其次,基于该图模型构建了含高比例光储的交直流混合配电网的协同调度模型,并推导了以顶点为中心的交直流混合配电网图计算方法,通过模型的分解和顶点并行计算提升模型的计算效率和可解性并保护用户隐私。最后,通过算例分析验证了所提方法的有效性。
In response to the problem of the unified modeling and collaborative computation of AC/DC hybrid distribution network with a high proportion of photovoltaic and energy storage
an optimal dispatch model of the AC/DC hybrid distribution network based on graph computing is constructed. First
an object-oriented graph model of the AC/DC hybrid distribution network is built by abstracting the equipment in the AC/DC hybrid distribution network as the vertex of the graph. Then
this paper constructs a collaborative dispatch model of the AC/DC hybrid distribution network with a high proportion of photovoltaic and energy storage based on the proposed graph model. And the method for the vertex-centered AC/DC hybrid distribution network graph computation is derived. The method improves the computational efficiency and solvability of the model and protects the privacy of the users through the decomposition of the model and the parallel computation of the vertices. Finally
the effectiveness of the proposed method is verified by case analysis.
