| 摘要: |
| 随着新能源占比的增大，电网调峰能力和频率稳定问题已成为新能源消纳的主要制约因素，提出一种考虑调峰、频率稳定以及机组调节性能等稳态、动态平衡条件约束下的新能源消纳能力综合评估方法。考虑联络线调峰，计算电网的新能源渗透率。通过应力和寿命之间的关系计算出机组频繁调节下的寿命损耗，分析对新能源接纳能力的影响。并把频率稳定作为重要约束条件，分析不同类型扰动例如一般扰动和严重故障限制下的新能源消纳水平。分析结果揭示了不同因素下的交互制约关系，提高了评估新能源消纳能力的系统性和适应性，并给出了相关建议。 |

| Abstract: |
| With the increase of the proportion of new energy sources, the peak load capacity and frequency stability of power grid have become the main constraint factors for the new energy consumption. This paper presents a comprehensive assessment method of new energy dissipation capacity under the constraints of steady and dynamic equilibrium conditions such as peak adjustment, frequency stability and unit regulation performance. The new energy permeability of the power grid considering the connection line peak adjustment is calculated, and the life loss under the frequent regulation of the unit is calculated by the relationship between the stress and the life to analyze the influence of the new energy acceptance capacity; the frequency stability is regarded as an important constraint condition, then the new energy consumption level under different types of disturbance such as general disturbance and serious fault is analyzed. The analysis reveals the interaction constraints under different factors and improves the systematicness and adaptability of the assessment of new energy consumption capacity. And relevant suggestions are given. This work is supported by National Key Research and Development Program of China (No. 2018YFB0904200). |
