Smart Power Grids Theme:

Traditional power systems have often been built on the basis of an electrical energy value chain which consists of a relatively few centralized and actively control thermal power generation facilities serving a relatively large number of distributed passive electrical loads. However, the IEEE Control Systems Society outlines five trends which are set to dramatically challenge the basic assumptions upon which the electric power grid was built. These are:

  1. Decarbonization of electric power generation
  2. Continued yearly growth of electricity demand especially in developing economies
  3. Electrification of the transportation sector
  4. Trends towards electric power deregulation
  5. Trends towards empowered consumers responsive to the grid's physical and economic conditions.
Taken together, these drivers virtually require a steadily increasing penetration of variable energy resources (VERs) into the power grid. As a result, the overall dispatchability of the generation fleet is set to decrease while the overall dispatchability of demand is set to increase. Naturally, power system assessment techniques should correspondingly evolve to accommodate that the control as well as the disturbance may originate from either generation or demand.

To address these needs, the LIINES Smart Power Grid Research Theme has made contributions in three areas:

Key Achievements in Smart Grid Thought Leadership:

LIINES has been fortunate to be a part of several smart grid thought leadership activities:
Key Achievements in Electric Power Enterprise Control Systems:

LIINES has also proposed Electric Power Enterprise Control Systems as a simulation approach that integrates a power grid’s multiple layers of operation and control so as to conduct holistic techno-economic assessments in the presence of large scale renewable energy, energy storage, & demand-side energy resources. This has lead to:
Key Achievements in Smart Grid Control Systems:

The LIINES has made several contributions to smart grid operation & control systems which individually may be implemented within the enterprise control approach. These include:
  • Small Signal & Transient Stability of the Physical Power Grid (2012 & 2013): Hussein Abdel-Halim investigated new approaches to tuning turbine governors in the presence of wind generation as well as new approaches to the placement of wind generators. Fang-Yu Liu is extending this work to include demand-side resources in the micro-grid domain.

Additionally, we have written several blog posts specifically on the topic of
Smart Power Grids @ the LIINES.
