Using the theory of system engineering and theory of control engineering, and considering the actual conditions of Hunan power nets and the situation ofthe Chinese electric power, as well as the theory of the two-part electrovalence, extra-base-point bidding and price-difference contracts & spot market, the "Combining dispatched by efficiency priority and price-difference contracts" is proposed. In this paper the real-load pricing of electricity bidding theory are also introduced.
As the developing of computer technology, communication technology andautomation in electric power industry, the 1024-bit RSA encryption system can not be breached in electricity bidding, and it can collect the system information intime, operate reliably, calculate truly and connect seamlessly with other systems,so it can provide a powerfully technical support for a fair, just, open and orderlyelectricity bidding market.
Based on the characteristics of electricity bidding and the demands of encryption techniques,the electronic comm ercial information technology is introduced into electricity bidding system.
