Summary: Future power systems must be able to provide a more secure, reliable, clean and high quality supply of electricity according to the consumer demands. There is an increasing demand on environmental friendly energy resources such as wind, solar and tidal. Because of the intermittent nature of most renewable energy resources, combinations of these resources into a unique system along with an energy storage system and alternative energy generators will improve system performances. This project proposes a hybrid multi-port converter (HMPC) topology for integrating several converters in a unique system which will reduce count of devices, cost and size of overall renewable energy system compared with several stage converters. Using a high frequency multi-winding transformer in this system provides galvanic isolation between all inputs and outputs and prevent of leakage current in some sources such as PV panels. The designed system will provide more reliable and faster management and control on input and output energy sources compared with multi-converter systems. The system can be designed to provide several features like bidirectional power flow, active and reactive power control, load management system, local and global power management system. This topology can provide five bidirectional and unidirectional ports and integrates the DC-DC and DC-AC conversion in a unique system, and would enable the system to supply both AC and DC loads, and/or to provide several single or three phase AC voltages of different frequencies and waveforms and DC voltages at the same time.
