Bio-inspired Design to Improve Power Grid Resiliency
Abstract: The electric power delivery
system must have few outages to meet the electrical energy needs of our everyday
life. Therefore, future investment focus should be on the power system
reliability. Modern power system has been undergoing considerable changes in
technology and planning. Technological advancements on smart grid includes
improved sensing, communication, automation and advance metering. Thus, the
modern electric power system becomes a complex cyber-physical system with many
components spread around the network. It is understandable that despite all
efforts there is potential for occasional large-scale outages especially due to
natural disasters. Major outages will have huge negative impact on human lives
and the economy. Therefore, there is an urgent need to increase power system
resiliency, decrease outages and at the same time reduce impacts on the society.
It is also important to lower the power network restoring time.
Strategies to enhance electric power resilience must accommodate both a diverse set of technical arrangements and a wide variety of hazards. There are many publications focusing on the different aspects of the power system with the intention of improving system resiliency. Among them, some recent publications discuss about the bio-inspired design to enhance sustainability and performance of systems such as power network. Bio-inspired design draw analogies between human and natural systems to identify biological principles that are useful for solving engineering problems.
Biological food webs have evolved over millions of years to manage and survive extreme events. These networks have already inspired the redesign of several organizational analogous human networks. Results indicate reduced environmental impacts and cost when design mimic food web characteristic structure. Power grid, in many ways, resembles food webs; both are made of components that exchange, use, and transform energy to meet the needs of the participants.
In this presentation, I will review work done in this area which demonstrate improved robustness of the electric power network through the understanding and application of the knowledge gained from biological food webs. Results points to increased system flexibility and redundancy, which lead to more resilient power grid.
