摘要: 针对含大规模新能源发电的电力系统评价角度较为单一且无法体现地区间的差异性的问题,提出一种地区差异化综合效益评价模型。该模型应用基于主、客观赋权法的综合赋权法,对电力系统可靠、经济、环保、高效四个方面加以评价,并引入地区系数概念,对评价指标进行差异化处理从而反映地区特征。选取3个具有代表性地区进行算例分析,评价结果表明,经济发达、人口密度较大的地区应更注重电力系统可靠性与环保性,电力投资敏感的地区可适当放宽电力系统的经济性要求。

关键词: 新能源, 地区差异, 电力系统, 评价模型

Abstract: The access of large-scale new energy will become a new feature of power systems in the future. At present, the evaluation on the power systems with large-scale new energy (PSLNE) are relatively simple, and can not reflect the differences between regions. The paper firstly analyzes the basic problems of power systems in the future, and then proposes a comprehensive evaluation model considering regional differences. A comprehensive weighting method, which is based on the subjective and objective weighting method, is used to evaluate the reliability, economy, environmental protection and efficiency of power systems. The concept of regional coefficient is introduced and the evaluating indices are differentiated to reflect the regional characteristics. Finally, three representative regions are selected for case study. The evaluation results show that the reliability and environmental protection of electrical power systems shall be given more attentions for the economically developed and densely populated areas, while the economy requirements may be relaxed appropriately for the areas where the power investment is sensitive.

Key words: new energy, regional difference, power system, evaluation model
