Expert Needed - Power World Grid Network Simulation
Budget: $3,000 – $5,000 USD
Must Have Expertise in Power World Software
Scope of Work
HEMP and GMD Impact Modeling
1. Using the available data, the network shall be modeled in the simulation tool in a way that allows each circuit to be assessed individually as well as holistically in a complete network. A circuit should be logically determined from the data and at a minimum should reflect a connection between nodes that include a grounding point or connections between other circuits (or both).
2. The simulation tool should use geophysical data and various GMD/E3 assumptions to determine ground potentials at each grounded node location for a given assumption set.
3. The simulation should be able to provide GIC currents flowing into and out of the node location (and to ground). These currents should reflect the currents flowing through transformers connected to ground (or as appropriate to other circuits).
4. The Simulations should include:
a. 400kV Network only - Standalone Analysis
b. 132kV + 400kV Combined Network Analysis
c. Analysis and Comparison of the results from the previous simulation (400kV only) and the new Analysis (both 400kV only and 400kV + 132kV combined)
d. Analysis and highlight the differences in the largest predicted GIC flow due to the addition of 132kV lines imposed upon the 400kV lines
e. Analysis and highlight the differences in the largest predicted reactive power results due to the addition of 132kV lines imposed upon the 400kV lines
f. Analysis of the largest predicted GIC flow upon the 132kV lines from the 400kV
+132kV integrated grid
g. Analysis of the largest predicted reactive power results upon the 132kV lines from the 400kV +132kV integrated grid
5. The simulation should be able to provide GIC winding currents through each transformer in a circuit so that damage likelihood estimates may be made for each transformer.
6. Outputs of the simulation should include tabular and graphical depictions (using node points of varying size (representing currents) and colors (representing current inflow or outflow).
7. Any network elements that are identified that do not connect to other nodes or network elements should be identified and listed as soon as possible so that they can be provided to the client.
8. All information on the simulation should be provided in readable (spreadsheet or other form) and in native form to the simulation tool.
9. A narrative of the results should be provided for each node and transformer that lists magnitude and direction of currents flowing into/out of the node. This should include a list of the top transformers of concern based on current magnitudes flowing through windings and any other technical concerns based on simulation results.
10. Suggest mitigation options and perform the same analyses as performed in Task #4 to show the impact of the proposed mitigation options on the grid.
