摘要: 为满足可再生能源大规模并网的发展趋势,提升系统对可再生能源的接纳能力,亟需规划建设具有高适应性的电网结构。基于联合加权熵理论,文章从适应可再生能源安全并网角度出发,提出一套面向电网规划的适应性指标体系。该指标体系同时考虑不确定运行环境下,电网潮流分布的安全性及稳定性,节点、支路的均衡性及合理性,通过分析电网实际状态及电气结构以评估可再生能源并网不确定环境下电力系统的安全性。然后,基于适应性指标建立输电网多目标规划模型,并采用带层次分析约束锥的数据包络分析法对Pareto非劣解集进行综合决策。最后,以Garver-18节点系统进行算例仿真,验证文章提出的指标体系及规划模型的合理性、有效性。

Abstract:  In order to meet the trend of large-scale integration of renewable energy to power grid, it is urgent to plan a grid structure with high adaptability to improve the systems capability to accept renewable energy. Applying the united weighted entropy theory, a series of adaptive indexes for power grid planning is proposed to analyze the security of power grid after renewable energy integration. In uncertain operation environment, the indexes consider the security and stability of power flow distribution, the balance and rationality of nodes and branches. By analyzing the actual state and electrical structure of the power grid, the security of the grid with renewable energy is evaluated. Then, a multi-objective programming model of transmission network is established on the basis of the adaptability indexes, and the data envelope analysis model with analytic hierarchy process restraint cone is used to make comprehensive decision on Pareto solution set. Finally, an example of Garver 18-node system is simulated to verify the rationality and effectiveness of the indexes and the planning model.

Key words:  united weighted entropy, safety adaptability, transmission grid planning, high penetration renewable energy
