Ensuring access to reliable and sustainable power supply is becoming more and more challenging due to a combination of factors such as more frequent power grid outages caused by extreme weather events, the large-scale introduction of renewable energy resources that increases the complexity of the power system, but also aging infrastructure, supply and demand imbalance and power theft in some areas. Combined, all these factors can cause outages and together they can make electricity supply unreliable. The implications of this are many, ranging from minor inconveniences to major failures of critical infrastructures. A potential solution to ensure power supply during outages is to use local generation in the form of renewable resources to supply energy. This paper proposes a community-based mechanism that demonstrates that when community members can determine for themselves how excess energy generation is distributed, the power supply of specific members can be ensured. Self-determination is achieved by prioritizing and differentiating between community members as well as automatically and continuously redistributing energy, thereby adapting to sudden changes in supply and demand. Simulation results show that the proposed mechanism can be used to empower local communities to decide for themselves how local resources are distributed during events such as outages, ensuring prolonged power supply for differentiated members of affected communities. Harnessing the potential of renewable resources and smart technologies for intelligent coordination through empowerment of consumers to become pro-active participants is a promising solution for the future power systems.

自行确定本地能源分布,以确保停电时的电力供应

由于多种因素的综合考虑,确保可靠和可持续的电源供应变得越来越具有挑战性,例如极端天气事件造成的频繁电网中断,大规模引入可再生能源增加了电力系统的复杂性,而且某些地区的基础设施老化,供需失衡和电力盗窃。所有这些因素加在一起可能导致断电,并且一起使电力供应不可靠。这样做的含义很多,从轻微的不便到关键基础架构的重大故障,不一而足。确保停电期间供电的潜在解决方案是使用可再生资源形式的本地发电来提供能源。本文提出了一种基于社区的机制,该机制表明,当社区成员可以自己确定多余的能量如何分配时,就可以确保特定成员的电源。通过在社区成员之间确定优先顺序并进行区分,以及自动连续地重新分配能量,从而适应供求的突然变化,实现自决。仿真结果表明,所提出的机制可用于授权本地社区自行决定在断电等事件期间如何分配本地资源,从而确保为受影响社区的不同成员提供较长的电源。
