摘要:
It is described an electronic device (1) to control the electrical energy delivered to an electric plant (40). The device comprises at least one sensor (2) configured to measure an electrical voltage and an electric current of the electric plant and to generate at least one measurement signal (S_ms) indicating said measurement of the electrical voltage and of the electric current. The device further comprises a control unit (3) electrically connected to the at least one sensor, the control unit being configured to receive the at least one measurement signal and to generate a switching signal (S_sw) indicating a connected or disconnected condition of a plurality of electrical loads (30, 31), wherein each of the electrical loads is switchable between the connected condition wherein the electrical load is electrically connected to the electric plant and a disconnected condition wherein the electrical load is electrically disconnected from the electric plant. The control unit is further configured to generate (110, 150) the switching signal having a value indicating the transition from the connected condition to the disconnected condition of at least one electrical load (31) out of the plurality of electrical loads, by means of an appropriate algorithm that takes into account the values of a first (P1_ct) and second (P2_ct) contractual electrical power threshold.
