储能电站对电网相称性混合的影响研究

Research on the Effect of Energy Storage Station on Assortative Mixing in the Power Grid

以电网发电-负载混合模式为研究对象,通过建立混合模式矩阵及计算相称系数等手段进行具体分析,研究表明电网具有介于随机网络与规则网络之间的中间特征,呈现非相称网络特征。通过建立基于随机模式和规则模式的储能电站接入模型,研究储能电站对电网相称性的影响。随着储能节点接入数目的增多,电网的相称性增强;规则接入方式更易影响相称性。

For the mixing pattern of generators and loads in the power grid, the parameterized mixing matrix and the assortativity coefficient are used in this paper. The results indicate that the grid is in between the random mixing case and the regular case and has disassortatively mixed characteristics. Based on the stochastic mode and the rules mode, the access model of the energy storage power station has been proposed. Moreover, the impacts of the energy storage power station for the assortativity of the grid have been studied. With the increase in the number of the energy storage power station, the assortativity of the grid increases. Furthermore, the rules mode access way is more likely to affect the assortativity of the grid.
