First, you would need to implement a Python package that contains the power system modeling and simulation algorithms. This package would need to include functions for modeling power system components and simulating various types of analyses, such as power flow, short-circuit, and transient stability.

Next, you would need to create a Python script that imports the power system package and uses it to simulate the chosen analysis. The script should also include a function for creating the user interface using tkinter. The user interface should include input fields for the system data, buttons for running the simulation and displaying the results, and graphical output for visualizing the simulation results.

To ensure proper destructive program exit that cleans up after itself, you can use the "destroy" method to close the tkinter window and release any system resources used by the application. You can also use exception handling to catch and gracefully handle any errors or unexpected events that may occur during the simulation.

Overall, creating a user-friendly power system simulation tool with a tkinter interface in Python would require a significant amount of time and effort, as well as expertise in power system engineering, numerical methods, and software development. It would be best to start with simpler examples and gradually build up to more complex simulations as you gain more experience and confidence in your abilities.
