Electricity supply system with heterogeneous multiple input.

The system has N-unidirectional converters connected to an input of a feed network (R1-RN) and supplying an electrical power (P1-PN) to a distribution bus (16). A controlling unit (20) controls the unidirectional converters. An energy storage device (18) is connected to the distribution bus and comprises a quantity of energy. The controlling unit is adapted to simultaneously control the unidirectional converters for regulating the electrical power provided by each of the unidirectional converters according to the amount of energy.
