基于系统动力学的智能配电网可持续发展能力评估

Evaluation on Sustainable Development Capability of Smart Distribution Network Based on System Dynamics

分布式电源、储能、柔性负荷等广义分布式资源接入配电网对提高可再生能源利用率、实现节能减排运行意义重大,是实现智能配电网可持续发展的重要手段。在计及广义分布式资源接入智能配电网的情况下,本文提出了一种智能配电网可持续发展能力评价指标体系,基于系统动力学理论建立了体现智能配电网可持续发展能力的评估模型,利用基于模糊理论、熵权法、层次分析法的综合评价方法对智能配电网可持续发展能力进行评分。最后,通过对含广义分布式资源的IEEE 33节点智能配电网算例进行测试,验证了所述评价体系的有效性。

The connection of generalized distributed resources （e.g., distributed generation, energy storage system, and flexible loads） to distribution network is an important measure to realize the sustainable development of smart distri- bution network, which has a great significance in increasing the renewable energy efficiency and achieving energy-sav- ing and emission-reduction. With the consideration of generalized distributed resources participating in smart distribu- tion network, an evaluation index system is proposed for the sustainable development capability of smart distribution network, and the corresponding evaluation model is established based on the theory of system dynamics. The sustain- able development capability of smart distribution network is scored by using a comprehensive evaluation method based on fuzzy theory, entropy weight method and analytic hierarchy process. Finally, the effectiveness of the proposed evalu- ation system is verified through tests on an IEEE 33-node smart distribution network containing generalized distributed resources.
