The work presented in this article proposes a new centralized control strategy for energy management in grid interactive hybrid micro grids using AC and DC electric springs based on the available generation. The planned control strategy is very simple to implement and requires few mathematical calculations. Unlike many offline algorithms presented in literature, the proposed methodology works based on the voltage level at the load and generation buses on real time basis. The specific aim of this work is to reduce the energy served by the main grid during demand supply gaps in the micro grids. The considered hybrid micro grid consists of both AC and DC loads broadly classified as critical and noncritical loads of which critical loads are considered as uncontrollable loads. In this article, the energy conservation from main grid is achieved by making noncritical loads consume less power during generation uncertainties in the microsources. The simulations models and studies of the proposed online control technique are performed in MATLAB.

利用电弹簧改善AC / DC微电网自主运行的实时控制策略

本文中提出的工作提出了一种新的集中控制策略，用于基于可用发电量的使用AC和DC电动弹簧的网格交互式混合微电网中的能源管理。计划的控制策略实施起来非常简单，几乎不需要数学计算。与文献中提出的许多离线算法不同，所提出的方法基于负载和发电母线上的电压水平实时工作。这项工作的具体目标是在微电网中的需求供应缺口期间减少主电网提供的能量。所考虑的混合微电网包括被广泛分类为临界和非临界负载的交流和直流负载，其中临界负载被视为不可控制的负载。在这篇文章中，通过使非关键负载在微源中产生不确定性期间消耗较少的功率来实现主电网的节能。在MATLAB中进行了在线控制技术的仿真模型和研究。
