Hello all, I am a student of Master of Electrical engineering studying in an Australian university. My Graduation project is about providing frequency control services to the grid using battery storage and it is going to be simulated in MATLAB. But the thing is that I am not very familiar with MATLAB's Simulink environment and was confused about how I can give frequency fluctuations and show that frequency can be stabilized using battery storage in a particular time frame? Any suggestion of mechanism to simulate such a system in Simulink. If not possible in Simulink than any suggestion of software that I can use to simulate such a system. Any suggestion would be a great help. Thank you.
