  1. Grid Modeling & Database Management for Energy Systems Analysis Ashish Gupta

  2. Developing The Infrastructure… • Extracting Power Plant Data • Converting Databases • Developing Software Tools to Analyze Data • Researching and Implementing Optimization Algorithms

  3. PJM Data Schematic Planning PSSE Model Bus ID, Bus Name EMS PSSE Model fk_ta_id Creating This Link via Machine Learning Techniques Pnodes 5-Minute Load Data Pnodes ID Bid Data Pnode Names

  4. A Peek at the Code….

  5. PJM Load Data • 52+ Gigabyte File • 2 Main Tools: 1. Byte Index 2. SQL Database

  6. The Processing Tools in Action

  7. Locational Marginal Pricing • Method for calculating energy cost at a particular node

  8. 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.

  9. Economic Dispatch Problem • Finding the optimal way to meet the load of the system • Must adhere to cost curves of each generator

  10. Lambda Iteration Method • Algorithm to efficiently compute generation power corresponding to a particular price

  11. Aggregate Bid Curve

  12. Putting it All Together
