Short summary

Multi-rotor wind turbines are an innovative solution to achieving cost-effective large-scale wind turbines. They utilize a large number of small rotors connected to one support structure instead of one large rotor. Benefits include reduction in cost, transport and installation simplicity, modular design, and standardization. This work compares different electrical systems in terms of cost, mass and efficiency and finds a star-type system (each rotor has its own cable) to be the most suitable.
