Title: Distribution%20Systems%20With%20Distributed%20Generation:%20Analysis%20And%20Operation


1
Distribution Systems With Distributed
GenerationAnalysis And Operation
  • Presented By Alex Rost
  • Supervised by Dr. Venkatesh, Dr. Diduch

2
Our Objective
  • Develop analysis tools and operational rules to
    improve the economic sustainability of smaller
    generators distributed throughout a distribution
    system.

3
Our Objective
  • Distributed generation scheme used for this
    project

4
Our Objective
  • Some Notes On Wind Energy
  • Costs have dropped by more than 80 in the last
    20yrs 1.
  • Fastest growing energy technology 20 annual
    growth for the last 5yrs 1.

5
Our Objective
  • Some Notes
  • In N.B.
  • Utilities required to allow embedded renewable
    generators to feed into the distribution system
    (gt100 kW up to transmission capabilities) 2
  • Projected that wind energy will supply 65 of
    R.P.S. by 2015 2

6
Our Methodology
7
What We Have Done
  • Voltage Collapse Index

8
What We Have Done
  • Voltage Collapse Index Advantages
  • Simple.
  • Uses only local measurements.
  • Easily implemented.

9
What We Have Done
  • Voltage Collapse Index

10
What We Have Done
  • Wind Generator / Inverter System
  • Can supply and absorb reactive power.
  • Modeled as a PV bus in steady-state.

11
What We Have Done
  • Distribution System With Distributed Generation
    Load Flow

12
What We Have Done
  • Load Flow Advantages
  • Tailored for radial distribution systems with
    high R/X ratios.
  • Fast
  • Flexible
  • Robust

13
What We Have Done
  • Distribution Load Flow Case

14
What We Want To Do Next
  • Distribution System Management
  • Optimal Reconfiguration to Minimize Losses.
  • Reactive Power Study.
