摘要
随着电力市场和新能源发电的不断发展,研究分布式发电的能量管理技术对分布式发电系统的稳定、经济运行具有非常重要的作用。本文介绍了分布式发电系统的网络拓扑,阐述了分布式发电系统能量管理的基本策略和光伏阵列发电预测的工作原理,提出了一种新颖的分布式发电系统能量管理控制算法。该算法根据发电单元的输出电能预测和储能单元的实时状态确定运行模式,采用模糊控制实时调控系统能量流动的方向和幅值,实现了系统运行成本最优化。
As the development of energy market and the interest for new energy recourses such as wind energy and solar energy, energy management system of distributed generation （DG） becomes significant for the stability and economic operation of the DG system. This paper introduces a basic structure of DG system and illustrates the principle of power forecasting using neutral network. Finally a novel energy management system of DG is proposed to realize the economic operation. The proposed system determines the operation mode according to the forecasted output power and the state of the battery. The fuzzy control is adopted to control the power flow for the sake of the optimization of operation costs.
