Abstract

The interconnection of large amounts of nontraditional generation causes problems in a network designed for 'conventional' operation. A microgrid consists of a combination of generation sources, loads and energy storage interfaced through fast acting power electronics. The aim of operating microgrid sub-systems is to move away from considering DG as badly behaved system components, of which a limited amount can be tolerated in an area, to 'good citizens'. The paper is focused on the development of a novel energy management system (EMS) based on the application of neural networks (NN). The EMS is able to autonomously make decisions and determine hour by hour the correct dispatch of generators with the final goal of minimising the global energy costs. The application of the EMS to a small test case has showed significant saves in the global energy bill by using typical Italian energy and fuel price data

基于智能EMS的微电网对能源市场的最佳参与
大量非传统发电的互连会给为“传统”运行而设计的电网带来问题。微电网由发电源、负载和通过快速作用电力电子接口的能量存储组合而成。操作微电网子系统的目的是将DG从视为行为不良的系统组件(一个地区可以容忍有限数量的DG)转变为“好公民”。本文研究了一种基于神经网络的新型能源管理系统的开发。EMS能够自主决策,并确定每小时发电机的正确调度,最终目标是将全球能源成本降至最低。EMS在一个小型测试案例中的应用表明,通过使用典型的意大利能源和燃料价格数据,可以显著节省全球能源费用
