分布式电源接入对电网的影响综述
An Overview of Influence on the Grid by Distributed Generation Access

随着社会经济的飞速发展，由于供电模式单一导致的连锁故障在大电网中的屡次发生，无法社会发展的需求；另一方面，能源短缺、环境污染问题愈发严重，已经成为电力建设不可回避的问题。以可再生能源为主的分布式电源具有灵活、安全、清洁等特点，为节省投资、降低能耗与污染、提高电力系统可靠性与灵活性提供了新的思路。本文从多个角度分析了分布式电源接入对电网的影响，以及现状分布式电源接入电网存在的问题，并对未来分布式电源的发展方向提出了展望。

Abstract: As the development of social economy, cascading failures caused by grid’s single power supply mode have happened some times, and that can’t meet the demand of social economy development. On the other hand, energy shortage and environmental pollution problem is inevitable for grid construction. Distributed generation represented by renewable energy generation is flexible, safe and clean, and it provides a new idea to relieve the shortage of energy, solve the environmental pollution problem, and improve the reliability and flexibility of the grid. This paper analyzes the influences on grid by distributed generation access and the problems of distributed generation access. The development direction of distributed generation is proposed.
