摘要
随着分布式发电与大电网联接的研究,使运行成本较高的分布式发电的经济利用成为可能.本文通过分析与大电网联接的可控分布式发电与大电网的供电年费用,建立了与大电网联接的可控分布式发电经济性判断模型和最优备用容量模型,在合理利用经济判断的基础上,对分布式发电的备用容量进行了优化.案例计算表明,模型正确可行,具有较强的适用性.本文的研究为可控分布式发电的合理利用提供了技术支持,为分布式发电与大电网联接、分布式发电的合理配置,降低供电成本做出了贡献.
With the research on distributed power generation embedded to power grid(EDG),the economic utilization of low economical DG is feasible.By analyzing the annual power supply cost of EDG and power grid,the economic utilization and cost-benefit analysis model of controllable EDG system reliability are founded in this paper.Based on the economic estimation of EDG and by the unserved energy cost quantifying the reliability,the optimal capacity of EDG is made.The case calcu- lation indicates that the models in this paper are right.The research in this paper provides technology supporting to the rational utilization of controllable EDG.It will be benefit to the distributed power generation embedded to the power grid,and decrease power supply cost.
