Integrating Distributed or Renewable Resources Minitrack

The capabilities and characteristics of innovative supply-side and demand-side technologies in the electric power industry, as well as power system operations, planning and markets are evolving rapidly. Efficient integration of distributed, variable and uncertain system resources with portfolios of existing resources requires evolution in planning, operational and control strategies. Policies and market structures must also continue to advance. This mini-track invites papers that address modeling, simulation and hardware developments, as well as economic analyses (such as market or rate design), system analyses and case studies, relating to planning, operations and control of distributed and renewable resources in electric power systems.

Session 1: Renewables and Distributed Energy Resources
Session Organizer and Chair: Charlie Smith, Charlie@variablegen.org

Electricity market restructuring, advances in energy generation technology and agreements on the reduction of global greenhouse gas emissions have paved the way for a large increase in the use of renewable generation connected at both the transmission and distribution level. With wind generation currently having the largest share of the new capacity, and solar generation having the highest rate of growth, this trend is expected to continue to produce an increasing amount of variability and uncertainty in system generation portfolios. A broad array of issues associated with the incorporation of large shares of variable generation (VG) into power system planning, design, and operation, including market operation, needs to be considered.

This session invites technical papers addressing new approaches, models and methods for the planning, design and operation of power systems with large or increasing shares of VG. A focus on the key issues of managing increased levels of variability and uncertainty on both the transmission and distribution system with new approaches to increasing system flexibility and incorporating VG plant output forecasting on all time scales, is encouraged. Integration of renewable resources will also require continuing innovation in technology capability to enable the participation of variable generation in AGC systems, ancillary service markets and distribution system management. New approaches to the evolution of the wind and photovoltaic plant design to enable this participation are necessary. This session will address some of the challenges and approaches to achieve these goals.


Session 2: Demand Response, Microgrids, and Storage
Session Organizer and Chair: Ward Jewell, ward.jewell@wichita.edu

Distributed energy resources (DERs) include customer-side generation, energy storage, flexible loads, and distribution-side sensing devices, and may or may not have coordinated operation as microgrids. There is an emerging consensus that DERs will play a critical role in providing services to the power system. Flexible loads can be scheduled to balance variable generation, microgrids and strategic storage can provide reliability and security and distributed sensing can offer unprecedented system visibility. Integration of DERs requires continuing innovation in control, optimization, and modeling, and technology to enable the participation in regulation and balancing services, ancillary service markets and distribution system management.

This session invites technical papers presenting new approaches, models and methods for planning, architecting, and operating interconnected power systems with significant DER penetration. We are especially interested in papers that focus on the role of DERs in responding to variability and uncertainty on both the transmission and distribution systems, as well as papers that study the economic aspects of integrating DERs.
