Implementation of a DSPACE- based standalone renewable energy supply feeding an isolated load

This paper deals with standalone small power generation employing three self-excited induction generators under varying speeds feeding an isolated load. The proposed system utilizes three-level cascaded H-bridge inverter for the three generators. The control scheme has the capability of regulating the output voltage for balanced operation of a three-phase isolated load under variable speed. The proposed control can be implemented using DSPACE 1104, and the experimental results are presented to demonstrate the effectiveness of the proposed controller for an isolated generating system.
