摘要
本文深入探讨了分布式发电接入对电力系统稳定性的影响，并提出了相应的改善对策。随着可再生能源技术的快速发展，分布式发电作为一种重要的能源补充形式，在电力系统中占据越来越重要的地位。然而，其接入也带来了诸多挑战，包括电网结构复杂性增加、潮流分布变化、电压稳定性问题以及保护与控制难度提升等。这些影响直接关系到电力系统的安全、可靠和高效运行。本文首先分析了分布式发电接入对电力系统稳定性的具体影响，包括电压波动、频率稳定性下降、暂态稳定性受到威胁等方面。随后，本文提出了一系列改善对策，包括合理规划分布式发电的接入位置与容量、优化配电网结构、应用先进的电力电子技术和控制策略、加强分布式发电与电网的协调调度、提高分布式发电系统的故障穿越能力、完善分布式发电接入标准与规范，以及推动分布式发电与储能技术的结合应用等。这些对策旨在从多个维度出发，全面提升分布式发电接入后的电力系统稳定性。通过本文的研究，不仅加深了对分布式发电接入影响机制的理解，也为电力系统在实际运行中应对分布式发电接入提供了有价值的参考和指导。

Abstract
This paper discusses the influence of distributed generation access on the stability of power system, and puts forward the corresponding improvement countermeasures. With the rapid development of renewable energy technology, distributed generation, as an important form of energy supplement, occupies an increasingly important position in the power system. However, its access also brings many challenges, including the increased complexity of the grid structure, power current distribution changes, voltage stability problems, and increased difficulty in protection and control. These effects are directly related to the safety, reliability and efficient operation of the power system. This paper first analyzes the specific influence of distributed generation access on the stability of power system, including voltage fluctuation, frequency stability decline, transient stability is threatened, etc. Subsequently, this paper puts forward a series of improvement countermeasures, including reasonable planning of distributed generation access location and capacity, optimize the distribution network structure, the application of advanced power electronics technology and control strategy, strengthen the coordination of distributed generation and power grid scheduling, improve the distributed generation system, improve the distributed generation access standards and specifications, and promote the combination of distributed generation and energy storage technology, etc. These countermeasures aim to comprehensively improve the stability of the power system after distributed generation access from multiple dimensions. Through the research of this paper, it not only deepens the understanding of the influence mechanism of the distributed generation access, but also provides a valuable reference and guidance for the power system to deal with the distributed generation access in the actual operation.
