由于现有算法的限制和约束,面向电力系统的电能质量评估方法不适用于含多种分布式能源的能源互联网。为了得到能源互联网综合质量情况,需要提出面向多种分布式能源的综合评估方法。基于国家电能质量、室内空气质量和污染物排放标准,提出了将动态权重函数、二维惩罚函数、突变决策理论和自组织特征映射网络用于能源互联网供能质量综合评估的应用思路。最后,采用2个算例验证了所提方法的有效性,并得到了能源互联网供能质量的综合指标数值和等级评估结果。
Due to the constraints and limitations of existing algorithms,the power quality evaluation methods of power system are not suitable for the energy internet with multiple distributed energy resources. A comprehensive evaluation method orienting to multiple distributed energy resources is proposed to assess the comprehensive quality of energy internet. An application concept based on the state standards of power quality,indoor air quality and pollutant discharge is proposed to apply the dynamic weight function,two-dimensional penalty function,catastrophe theory and self-organizing feature map network to the comprehensive evaluation of energy quality for the energy internet. The validity of the proposed method is analytically verified by two cases,and the energy quality indexes and levels of energy internet are comprehensively evaluated.
