摘　　要：为探讨分布式能源接入对配电网稳定性的影响,分析3种典型的接入模式:直接接入模式、逆变器接入模式以及混合接入模式,从电压稳定性、频率稳定性、暂态稳定性以及小信号稳定性4个方面进行了深入研究。研究表明,不同接入方式对配电网的稳定性影响各异,逆变器接入模式在提高电压稳定性方面表现优越,但频率稳定性较弱;直接接入模式提供了较好的频率稳定性,但对暂态过程冲击较大;混合接入模式综合了两者的优势,是一种较为平衡的接入方案。未来的研究应关注高渗透率下的优化策略,以进一步提升配电网的整体稳定性。To explore the impact of distributed energy access on the stability of distribution networks,this article analyzes three typical access modes:direct access mode,inverter access mode,and hybrid access mode,and conducts in-depth research from four aspects:voltage stability,frequency stability,transient stability,and small signal stability.Research has shown that different access methods have varying impacts on the stability of distribution networks.The inverter access mode performs better in improving voltage stability,but has weaker frequency stability;The direct access mode provides good frequency stability,but has a significant impact on transient processes;The hybrid access mode combines the advantages of both and is a relatively balanced access solution.Future research should focus on optimization strategies under high penetration rates to further enhance the overall stability of the distribution network.
