With the UK’s commitment to reaching net-zero emissions and advancing clean energy technology, renewable energy has become a central topic in engineering education. For students pursuing electrical, mechanical, environmental, or sustainable energy degrees, mastering tools like MATLAB is essential.
This article explores how MATLAB is used to model, simulate, and analyse renewable energy systems—especially solar, wind, and hybrid setups—and why UK students should consider learning it for academic and career success.
Why MATLAB for Renewable Energy?
MATLAB provides a comprehensive environment to design, simulate, and optimise energy systems. It offers access to toolboxes like:
Simulink – for dynamic modelling and system simulations
Simscape Electrical – for electrical network modelling
Simscape Multibody – for mechanical system integration
Optimization Toolbox – for improving system performance
MATLAB App Designer – to create interactive simulation interfaces
These tools make MATLAB a preferred platform for renewable energy analysis in both academia and industry.
Applications of MATLAB in Renewable Energy
- Solar Energy System Simulation MATLAB can model the entire solar PV (photovoltaic) system including:
PV panels
Inverters
Maximum Power Point Tracking (MPPT)
Energy storage (batteries)
Grid interface

Edit
I = @(V) Is*(exp((q*V)/(n*k*T))-1); % Ideal PV model
V = linspace(0, 0.6, 100);
plot(V, I(V));

MATLAB also supports real irradiance and temperature datasets from the UK Met Office or other platforms.
- Wind Turbine Modelling Simulink can simulate wind turbine systems using mechanical and electrical components:
Blade rotation and aerodynamics
Generator and gearbox modelling
Wind speed variations
MPPT for wind energy
Grid-tied and standalone systems
Example: Wind Speed to Power Output

V = 5:0.1:25; % Wind speed in m/s
Cp = 0.4; % Power coefficient
A = 50; % Rotor area (m^2)
rho = 1.225; % Air density
P = 0.5 * rho * A * Cp .* V.^3;

3. Hybrid Energy Systems
Hybrid systems combine solar, wind, diesel generators, and batteries. MATLAB can simulate:
Load demand profiles
Energy dispatch strategies
Battery charging/discharging cycles
Cost optimisation (Levelised Cost of Energy - LCOE)
Simscape Electrical helps simulate switching between sources and balancing energy supply.
Real-Time Data and Control
For students working with real hardware, MATLAB interfaces with:
Arduino and Raspberry Pi
IoT sensors
Weather monitoring stations
Energy meters and data loggers
With ThingSpeak, MATLAB can also access and analyse live IoT data, perfect for smart grid and renewable monitoring projects.
UK-Focused Applications
MATLAB supports renewable energy research and simulation using UK-specific data, such as:
National Grid electricity prices and demand curves
Solar irradiance and wind speed datasets from UK Met Office
Simulation of domestic and commercial energy usage patterns
These can be used in coursework or final-year projects related to smart homes, electric vehicles (EVs), or microgrids.
