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
AGGREGATE BID CURVE
PUTTING IT ALL TOGETHER
