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
