摘要:

分布式电源(distributed generation,DG)并网对配电网的经济性、服务质量、安全性、环保效益等产生影响,基于此提出了一种对含有DG的配电网进行综合评估的有效方法。根据风力、光伏发电的特点,建立了风速、光照强度的正态分布模型,确定其出力情况从而计算配电网可靠性。从经济性、服务质量、安全性和环保效益4个方面考虑建立了综合评估指标体系。以IEEE RBTS-Bus6 系统的F4馈线作为测试系统,对DG不同接入方案下配电网各项评价指标进行仿真计算,并运用模糊层次分析法得到各方案综合得分。算例结果表明,多种类DG并网能有效改善电网的各项评价指标。

Abstract:

As many factors must be considered when distributed generation (DG) integrating the distribution,an efficient method for evaluating distribution network is proposed in this paper. According to the feature of wind power and solar power, normal distribution of wind speed and light intensity is established to calculate their output power and the reliability of network. Taking the economy, quality of service, safety and environment efficiency into consideration, this paper established the evaluation system and summarize the calculating methods. The indices under different situations are calculated based on the IEEE RBTS-Bus6 system. Fuzzy analytic hierarchy process (FAHP) was adopted to obtain the quantitated comprehensive evaluation results. The evaluation results show that multiple DG integrating into grid could promote the indices efficiently.
