Abstract

The future of power system will be highly influenced by Microgrid and Smart Grid with renewable energy resources. A standalone Microgrid suffer by intermittent generation and lack of supply due to harsh environment condition. Demand Side Management (DSM) manipulates demand instead of generation to increase energy efficiency. The existing DSM is developed by utilities including financial incentive plan, load efficiency and etc. to improve load factor. These plans are required adjustment and improvement to meet vulnerable stand-alone system with limited source. Interactive demand responses with SMS and direct access to individual load are introduced for DSM. This work intentionally shows a vulnerable Microgrid system with limited source to highlight the DSM function. DSM controller modeled and simulated in Simulink. The proposed DSM module, isolate the loads based on predefined load priority. Different scenarios for generation units are simulated to test DSM action in different situation. It will reduce unnecessary investment to generation unit expansion and will improve load factor.

脆弱混合微电网的创新需求侧管理

可再生能源微电网和智能电网将对电力系统的未来产生重大影响。一个独立的微电网由于恶劣的环境条件而遭受间歇性发电和供应不足的困扰。需求侧管理(DSM)通过控制需求而不是发电量来提高能源效率。现有的电力需求侧管理是由公用事业公司开发的，包括财政激励计划、负荷效率等，以提高负荷系数。这些方案需要调整和改进，以满足脆弱的单机系统和有限的资源。在需求侧管理中引入了具有SMS和直接访问单个负载的交互式需求响应。本工作有意展示了一个脆弱的有限源微电网系统，以突出需求侧管理功能。在Simulink中对DSM控制器进行了建模和仿真。提出的DSM模块基于预定义的负载优先级对负载进行隔离。通过对发电机组不同工况的模拟，测试不同工况下电力需求侧管理的作用。它将减少对发电机组扩建的不必要投资，并将提高负荷系数。
