The Data Declaration and Information Issuance System in Power Bidding for Power System

The implementation of power bidding is an important measure and an inevitable trend in the commercialization of power. This paper introduced the function of the system and systematically discussed the work principle of the Client, Supervision and Server. Based on the characteristics of electricity bidding and the demands of encryption techniques, the public secret-key arithmetic RSA was adopted in the system, which formed the integrated techniques of encoding, decoding, ID-checking and evidence-saving from damage. This paper expounds the RSA encryption arithmetic and the encryption of the bid document of the public key. The bid arithmetic of the price precedence of the power bidding was put forward based on relevant policies of Hunan province. The principle of the bid was introduced. The bid arithmetic can ensure the fair competition among power corporations, reduce the cost of electric generation and lower the electricity price in the end consumer. It has been applied in Hunan's power companies, and provided a powerful technical support for a fair and open power bidding market.
