摘要:

首先概述了在风电和光电方面发展比较领先的国家在电力系统规划评价方面已取得的成果和经验。然后, 分析了高渗透率间歇性电源并网与电力网络规划之间的相互影响, 并在此基础上对含高渗透率间歇性电源的电力网络规划综合评价指标体系做了初步探索。以传统指标体系为基础,引入了风险评估、接纳间歇性电源最大能力、输电能力、间歇性电源可置信容量及污染物减排量等指标, 来评估间歇性可再生能源规模化并网后的网络规划方案的经济性、供电质量、灵活性、环保性等。最后, 针对巴西南部46节点系统的2个备选网络规划方案对所提评价指标体系做了说明。分析结果表明,间歇性电源接入电力系统的适应程度对电力系统接纳间歇性电源的能力和运行风险具有重要影响, 因此在确定电力网络规划方案时需要在经济性与对间歇性电源并网的适应性方面适当折衷。

Abstract:

This paper firstly summarized the achievements and experiences of power system planning evaluation in countries with leading development in wind power and photovoltaic power. Then, the interactions between grid-connected  intermittent generations(IGs) with high penetration and power network planning were analyzed, and on this basis, the comprehensive evaluation index system of power network planning was preliminarily studied, which could characterize large-scale IGs after grid-connected. Based on traditional index system, some indicators such as the risk assessment, the maximum integration capacity of IGs, the transmission capability, the credible capacity of IGs, and the pollutants emission reduction, were used to evaluate the power network planning schemes of IGs after large-scale grid-connected from aspects of economics, power supply quality, flexibility, environmental friendliness, etc. Finally, two alternative power network planning schemes in southern Brazil 46-node system were applied to demonstrate the proposed evaluation index system. The analysis results show that the adaptability degree of IGs integrations into a power system has significant impact on the IGs accommodation capability and operation risk of the power system. Therefore, during determining power network planning scheme, it is necessary to make a compromise between the economics and adaptability of grid-connected IGs.
