A Residential Interactive End-Use Electric System With Electrical Engineering Materials Based on RTP and Load Forecasting

As smart grid has been under rapid construction in China, this paper proposes an interactive information system according to the interaction feature of smart grid. End users are able to exchange electricity usage information with power utilities by using this system. Structures and functions of this system are demonstrated first. Smart meter plays a key role in the whole system and it is connected with other parts of the system by GPRS and serial communicating paths. Subsystems both of grid side and users side are designed in details. Information of real-time pricing(RTP) and load forecasting is applied to motivate users to participate the operation of the grid actively so that energy resources could be optimized and finally goals of economical and high-efficient using of energy can be achieved.
