Local controllable load system

The invention relates to a local controllable load system for operating at least one electrical device (10), to be part of a general electrical system comprising a general power supply (200) of electrical current of a first type, the at least one electrical device (10) operating with an electrical current of a second type, the local controllable load system (100, 100') comprising: - a converter (20) to be connected to the general power supply (200) for converting said electrical current of the first type into said electrical current of the second type delivered to the other elements of the local controllable load system through a converter output (22); - a power storing device (30), delivering electrical current of the second type, and connectable to the converter output (22) for storing the power; - a first channel (1) to connect the converter output (22) to the at least one electrical device (10); - a second channel (2) to connect the power storing device (30) to the at least one electrical device (10); - a first charge controller (40) adapted to modify first and second electrical current values supplied to the at least one electrical device (10) through, respectively, the first and the second channels (1, 2), depending on information about the general electrical system. The invention relates also to a method of locally controlling the power of said local controllable load system (100, 100').
