PowerSync_System

CPS_PowerSync_System

This project proposes an optimized power delivery solution for EV charging stations using leader election and distributed computing algorithms. By applying cyber-physical systems (CPS) concepts, it enhances charging infrastructure efficiency, supporting sustainable and intelligent energy management.

The project has been implemented in MATLAB Simulink, utilizing the SimEvents, Stateflow, and Simulink Test libraries.

Execution Guide

The simulation was developed in MATLAB Simulink R2024a. To run the simulation, the following add-ons must be installed:

• Stateflow
• SimEvents

Then, follow these steps:

1. Clone the repository.
2. Ensure that Python is installed (specify version if necessary).
3. Verify that the files CPS_PowerSync_System.slx, rand.py, and check_variables.m are all within the same directory.
4. Open the file CPS_PowerSync_System.slx.
5. Load the variables into the base workspace via the file Data/base_ws_variables.mat.
6. Start the simulation or proceed step-by-step.

Test Guide

In the Test directory, there is a modified version of CPS_PowerSync_System.slx, set up to execute and verify the model requirements through the relevant assessments.

To run the tests and analyze the verification of specifications:

1. Install the Simulink Test add-on.
2. Open the file Test/TestCase.mldatx.

Previews

Graph showing how the charging points come to a consensus in relation to vehicle power requirements.

The functions depicted with continuous lines represent the average value estimates calculated through the Push-Sum modules. The dotted lines represent the power requests. The colors distinguish the different nodes (charging points) in the network.

Graph showing the value of the SoC of the vehicle connected to CP1.

The function represented by the darker color shows the SoC (State of Charge) of the vehicle, while the lighter color represents the average value estimate calculated via the Push-Sum module at charging point 1.
