Bidirectional metering power consumption management system and method

The invention relates to a bidirectional metering power consumption management system and method. The bidirectional metering power consumption management system and method comprise a processor module, a communication module, a double channel bidirectional metering module and a load control module, wherein the processing module, the communication module, the double channel bidirectional metering module and the load control module are respectively connected with the processor module; the communication module receives the electricity price data and a demand response signal of an electrical power system and sends the electricity price data and the demand response signal to the processor module; the double channel bidirectional metering module performs real-time metering of the electric energy data of a user, and sends the electric energy data of the user to the processor module; the processor module processes the electricity price data and the electric energy data of the user to acquire the cost data information, and transmits the cost data information to the electrical power system through the communication module, and also sends a load control signal to the load control module based on the demand response signal; and the load control module receives the load control signal, and controls on/off of a load switch according to the load control signal. The bidirectional metering power consumption management system and method can realize comprehensive power consumption management of distributed power accessing home, and can maximize the benefit of the electricity consumer.
