TRANSMISSION DISTRIBUTION LINES

ELECTRICAL TRANSMISSION AND DISTRIBUTION SYSTEM
5
TRANSMISSION LINE CHARACTERISTICS

• Connects generation to load to bring power to
  load centers. (See FERC Seven Factor test).
• Transfer power across state lines and across
  control regions.
• 115 kV and above Federally
• regulated.
• Lower voltage can serve
• electric customers and/or
• wholesale power market.

500 kV distribution line
6
DISTRIBUTION LINE CHARACTERISTICS

• Voltages are lt 100kV, typically at or below 34.5
  kV.
• Primarily bring electricity
• to customers.
• Traditionally, power flows
• into the line but not out.
• State regulated system.

DISTRIBUTED GENERATION

• Generation sited at or near load, behind the
  meter.
• Typically connected to the distribution system.
• Differing ownership
• structures possible.
• State definition
• is 10 MW and
• under.

10
DISTRIBUTED RESOURCES

• Includes distributed generation and demand side
  strategies such as conservation, efficiency, and
  load management.

11
DISPERSED GENERATION

• Stand alone generators not at existing retail
  customer sites.
• 100 of output injected into the grid.
• No size limits, current DOC study looking at
  10-40 MW sizes.
• Can be connected to either distribution or
  transmission lines.

WEST CENTRAL CBED STUDY
57 locations with generation Study performed by
CapX 2020 Utilities
1400 MW modeled without adding additional power
lines

WHAT THE C-BED STUDY LOOKED AT

• Analyzed thermal line loading and voltage levels
  for 800 MW and 1400 MW of Dispersed Generation at
  21 locations.
• Generation used to reduce Minnesota natural gas
  power plant output.
• Analyzed transmission system constraints and
  established costs for fixing thermal and voltage
  problems.

15
STUDY RESULTS

• 800 MW of Dispersed Generation
• 49 M in transmission fixes.
• 1400 MW of Dispersed Generation
• 97 Million in transmission fixes.
• No major new power lines were needed.

Distributed Wind Generation Study for
Northeastern Colorado

• Performed by Wind Utility Consulting for the
  Colorado Governors Office of Energy Management
  and Conservation and the Department of Energys
  Wind Powering America program
• Year 2005
• Location Highline Electric Association
  distribution grid NE Colorado
• Results showed that 63 GE 1.5 MW wind turbines or
  94.5 MW of wind could be incorporated into the
  distribution system

Shows Red Willow Substation with 4 turbines at a
maximum distance of 5.5 miles from the
substation.
