A PEEK AT THE CODE….
PJM LOAD DATA
52+ Gigabyte File
 2 Main Tools:

1. Byte Index
2. SQL Database
THE PROCESSING TOOLS IN ACTION
LOCATIONAL MARGINAL PRICING

Method for calculating energy cost at a particular
node
POWER TRANSFER DISTRIBUTION
FACTORS

Determines increases in flows on branches given
power injections at given nodes
P: Node injections (the variable). D: Branch susceptances.
A:node-arc incidence. B’: Powerflow. Theta: Nodal Phase Angles.
PB is power transfer distribution factor matrix.
ECONOMIC DISPATCH PROBLEM
Finding the optimal way to meet the load of the
system
 Must adhere to cost curves of each generator

LAMBDA ITERATION METHOD

Algorithm to efficiently compute generation
power corresponding to a particular price
