Plan of power utilization of time-of-use power price through smart grid user interface

The implement of peak and valley time sharing electricity price is the important measure to regulate power load fluctuation and promote load rate. We build a domestic communication network of WIA in customer´s home, in order to make air conditioners and the other appliances connect with each other. In order to get reasonable solution of power utilization, we establish a nonlinear mathematical model, which takes the different consumptions of various appliances into parameters. Since there are the optimizations of min (max) and multi-objects in the model, for solving it, first transform the objects into the restriction condition, which will construct the new multi-objects nonlinear model, then the most satisfactory method in the fuzzy matches is adopted to solve the multi-objects model. With the optimal solution, we get the reasonable plan for customers. The result shows that establishing appropriate time-of-use (TOU) power price can shift peak load and optimize resources in society.
