摘要: |
针对目前微电网控制器成本较高、标准各异、集成度低和缺乏具有实际操作性的能量管理策略等问题,设计了一种集计量监控和能量管理一体化的园区微电网中央控制器。采用基于ARM的嵌入式系统硬件平台,模块化设计。考虑到园区企业用能需求,开发了具有园区特色的能量管理策略,给出一种基于三次指数平滑法的需量预测方法并利用储能系统来进行需量管理,在不影响企业办公生产的同时降低用电成本。通过搭建物理实验平台对中央控制器的功能和能量管理策略进行了验证,具有较好的实用性。 |

Abstract: |
Aiming at the problems of higher cost, different standards, low integration, and lack of practical operational energy management strategies for microgrid controllers, a microgrid central controller integrating measurement, monitoring and energy management is designed. The controller utilizes ARM-based embedded system hardware platform and modular design. Considering the energy needs of enterprises in the park, some new energy management strategies according to the unique characteristics of the park are designed. The demand forecast based on the triple exponential smoothing method is proposed and the energy storage system is used for demand management to reduce the electricity cost of the enterprise without affecting the business and production. The function and energy management strategy of the central controller are also proved by establishing a physical experiment platform, showing its better practicality. This work is supported by National Key Research and Development Program of China (Key Technologies and Demonstrative Application for the Integration and Consumption of Clustered Distributed Renewable Energy Generation) (No. 2016YFB0900400). |
