基于分布式电源的孤立系统规划初探

Isolated power system planning based on distributed generation

现代自动化信息化技术的广泛应用对重要场所供电保障系统可靠性提出了很高要求,分布式发电技术和孤立电力系统的发展为提供新型可靠性供电提供了新的选择。提出分布式电源应用于孤立系统提高系统供电安全可靠性的思想,介绍了分布式发电技术,阐述了分布式电源提高孤立系统可靠性的基本思路,在充分考虑分布式电源不同形式、冷热电联产系统等因素基础上,建立了分布式电源的经济模型,研究了孤立电网规划模型。算例计算证明了规划模型的正确性和有效性,并表明了分布式电源对孤立系统可靠性提高的显著作用。

Modern equipments are extensively used and they need high reliability power supply urgently. In many cases, distribution systems will turn into isolated power system and their reliability drop sharply. This paper introduces distributed generation into isolated power system planning, a mathematic model is built to describe the influence of distributed generation on reliability, and several economic and reliability factors are considered. An example is used to demonstrate the effect of distributed generation which shows satisfactory results.
