A price fluctuation module in market oriented grid based on contract management

Price leverage plays a significant role in regulating the balance between supply and demand in traditional commodity market, so does it in Grid Market. Based our previous work, a price fluctuation module and relevant price strategies proposed in this paper are employed into the Market Oriented Grid Model (MOGM). The changes of supply-demand cause price fluctuation and the fluctuated price reflects supply-demand changes in return. Reasonable prices will help keeping the market in healthy operations. So, the price fluctuation management discussed in this paper can regulate and control the supply-demand balance. Simultaneously, the dynamic floating price can promote the successful rate of transactions. The results of simulation experiments reveal that the new module with price fluctuation strategies is effective.
